This was completely broken: it compared the first item of the filter
list only. Apparently I forgot that this is a list. This probably broke
aspects of runtime filter changing probably since commit b16cea750f52.
Fix this, and remove some redundant code from obj_settings_equals().
Which is not the same as m_obj_settings_equal(), so rename it to make
confusing them harder. (obj_setting_match() has these very weird label
semantics that should probably just be killed. Or not.)

The exact type name (m_obj_list_t) was removed in 2013. I don't think
this stub comment helps much with understanding this complicated thing
anyway (this code is for the --vf/--af options, and makes up almost half
of m_option.c).

Looks like this will be needed for fine-grained option change
notifications. There are some other parts in the player which implement
parts of this.

Until now, using a filter not in mpv's builtin filter list would assume
it's a libavfilter filter. If it wasn't, the option value was still
accepted, but creating the filter simply failed. But since this happens
after option parsing, so the result is confusing.
Improve this slightly by checking filter names. This will reject truly
unknown filters at option parsing time. Unfortunately, this still does
not check filter arguments. This would be much more complex, because
you'd have to create a dummy filter graph and allocate the filter. Maybe
another time.

This is preparation to get rid of the option-to-property bridge
(mp_on_set_option). This is a pretty insane thing that redirects
accesses to options to properties. It was needed in the ever ongoing
transition from something to... something else.
A good example for the need of this bridge is applying profiles at
runtime. This obviously goes through the config parser, but should also
make all changes effective, for which traditionally the property layer
is used.
There isn't much left that needs this bridge. This commit changes a
bunch of options (which also have a property implementation) to use
option change notifications instead. Many of the properties are still
left, but perform unrelated functions like OSD formatting.
This should be mostly compatible. There may be some subtle behavior
changes. For example, "hwdec" and "record-file" do not check for changes
anymore before applying them, so writing the current value to them
suddenly does something, while it was ignored before.
DVB changes untested, but should work.

Options marked with this flag were changed to strictly read-only after
initialization (mpv_initialize() in the client API, after option parsing
and config file loading with the CLI player).
This used to be necessary, because there was a single option struct that
could be accessed by multiple threads. For example, --config-dir sets
MPOpts.force_configdir, which was read whenever anything accessed the
mpv config dir (which could be on different threads, e.g. font
initialization tries to lookup fonts.conf from an arbitrary thread).
This isn't needed anymore, because threads now access these in a thread
safe way. In the case of --config-dir, the path is actually just copied
on init.
This M_OPT_FIXED mechanism is thus not strictly needed anymore. It still
prevents writing to some options that cannot take effect at runtime, but
even that can be dropped. In general, all mpv options can be changed any
time at runtime, even if they never take effect, and there's no need to
make an exception for a very low number of options. So just get rid of
it.

Internally, vo_gpu uses NaN for some options to indicate a default value
that is different depending on the context (e.g. different scalers).
There are 2 problems with this:
1. you couldn't reset the options to their defaults
2. NaN is a damn mess and shouldn't be part of the API
The option parser already rejected NaN explicitly, which is why 1.
didn't work. Regarding 2., JSON might be a good example, and actually
caused a bug report.
Fix this by mapping NaN to the special value "default". I think I'd
prefer other mechanisms (maybe just having every scaler expose separate
options?), but for now this will do. See you in a future commit, which
painfully deprecates this and replaces it with something else.
I refrained from using "no" (my favorite magic value for "unset" etc.)
because then I'd have e.g. make --no-scale-param1 work, which in
addition to a lot of effort looks dumb and nobody will use it.
Here's also an apology for the shitty added test script.

Removes a good hunk of weird code.
This loses qscale "emulation", some logging, and the fact that duplicate
keys for values starting with +/- were added with AV_DICT_APPEND. I
don't assign those any importance, even if they are user-visible
changes.
The new M_OPT_ flag is just so that nothing weird happens for other
key-value options, which do not interpret a "help" key specially.

Aliases that set old options are not needed anymore. Also extend the

Most options starting with --no-<name> are automatically translated to
--<name>=no. Make the code slightly nicer by using a flag instead of
explicitly comparing option types. Also fix an issue that made the
option parser print nonsense error messages for if --no-... was used for
options which don't support it.

--vf=help will now list libavfilter filters, and e.g. --vf=yadif=help
will list libavfilter filter options.
The latter is rather bare, because the AVOption API is really awful
(holy shit how is it so bad), and would require us to handle _every_
option type manually.
Alternatively we could call av_opt_show2(), which ffmpeg uses for help
output in its CLI tools and which is much more detailed. But it's rather
foreign and forces output through av_log(), so I don't really want to
use it.

Get rid of the old vf.c code. Replace it with a generic filtering
framework, which can potentially handle more than just --vf. At least
reimplementing --af with this code is planned.
This changes some --vf semantics (including runtime behavior and the
"vf" command). The most important ones are listed in interface-changes.
vf_convert.c is renamed to f_swscale.c. It is now an internal filter
that can not be inserted by the user manually.
f_lavfi.c is a refactor of player/lavfi.c. The latter will be removed
once --lavfi-complex is reimplemented on top of f_lavfi.c. (which is
conceptually easy, but a big mess due to the data flow changes).
The existing filters are all changed heavily. The data flow of the new
filter framework is different. Especially EOF handling changes - EOF is
now a "frame" rather than a state, and must be passed through exactly
once.
Another major thing is that all filters must support dynamic format
changes. The filter reconfig() function goes away. (This sounds complex,
but since all filters need to handle EOF draining anyway, they can use
the same code, and it removes the mess with reconfig() having to predict
the output format, which completely breaks with libavfilter anyway.)
In addition, there is no automatic format negotiation or conversion.
libavfilter's primitive and insufficient API simply doesn't allow us to
do this in a reasonable way. Instead, filters can use f_autoconvert as
sub-filter, and tell it which formats they support. This filter will in
turn add actual conversion filters, such as f_swscale, to perform
necessary format changes.
vf_vapoursynth.c uses the same basic principle of operation as before,
but with worryingly different details in data flow. Still appears to
work.
The hardware deint filters (vf_vavpp.c, vf_d3d11vpp.c, vf_vdpaupp.c) are
heavily changed. Fortunately, they all used refqueue.c, which is for
sharing the data flow logic (especially for managing future/past
surfaces and such). It turns out it can be used to factor out most of
the data flow. Some of these filters accepted software input. Instead of
having ad-hoc upload code in each filter, surface upload is now
delegated to f_autoconvert, which can use f_hwupload to perform this.
Exporting VO capabilities is still a big mess (mp_stream_info stuff).
The D3D11 code drops the redundant image formats, and all code uses the
hw_subfmt (sw_format in FFmpeg) instead. Although that too seems to be a
big mess for now.
f_async_queue is unused.

And use it for 2 demuxer options. It could be used for more options
later. (Though the --cache options can not use this, because they use KB
as base unit.)

This is part of trying to get rid of --af-defaults, and the af
resample filter.
It requires a complicated mechanism to set the defaults on the resample
filter for backwards compatibility.

This allows us to automatically trigger a VOCTRL_RESIZE (also contained).

Some old crap which nobody needs and which probably nobody uses.
This relies on a GCC extension: using "## __VA_ARGS__" to remove the
comma from the argument list if the va args are empty. It's supported
by clang, and there's some chance newer standards will introduce a
proper way to do this. (Even if it breaks somewhere, it will be a
problem only for 1 release, since I want to drop the deprecated
properties immediately.)

The internal stereo3d filter was removed due to being GPL only, and due
to being a mess that somehow used libavfilter's filter. Without this
filter, it's hard to remove our internal stereo3d image attribute, so
even using libavfilter's stereo3d filter would not work too well (unless
someone fixes it and makes it able to use AVFrame metadata, which we
then could mirror in mp_image).
This was never well thought-through anyway, so just drop it. I think
some "downsampling" support would still make sense, maybe that can be
readded later.

This removes all GPL only code from it, and that's the whole purpose.
Also happens to be much simpler.
The "deinterlace" option still sort of exists, but only as runtime
changeable option. The main change in behavior is that the property will
not report back the actual deint state. Or in other words, if inserting
or initializing the filter fails, the deinterlace property will still
return "yes". This is in line with most recent behavior changes to
properties and options.

So far, we had a thread-safe way to read options, but no option update
notification mechanism. Everything was funneled though the main thread's
central mp_option_change_callback() function. For example, if the
panscan options were changed, the function called vo_control() with
VOCTRL_SET_PANSCAN to manually notify the VO thread of updates. This
worked, but's pretty inconvenient. Most of these problems come from the
fact that MPlayer was written as a single-threaded program.
This commit works towards a more flexible mechanism. It adds an update
callback to m_config_cache (the thing that is already used for
thread-safe access of global options).
This alone would still be rather inconvenient, at least in context of
VOs. Add another mechanism on top of it that uses mp_dispatch_queue, and
takes care of some annoying synchronization issues. We extend
mp_dispatch_queue itself to make this easier and slightly more
efficient.
As a first application, use this to reimplement certain VO scaling and
renderer options. The update_opts() function translates these to the
"old" VOCTRLs, though.
An annoyingly subtle issue is that m_config_cache's destructor now
releases pending notifications, and must be released before the
associated dispatch queue. Otherwise, it could happen that option
updates during e.g. VO destruction queue or run stale entries, which is
not expected.
Rather untested. The singly-linked list code in dispatch.c is probably
buggy, and I bet some aspects about synchronization are not entirely
sane.

Tends to be somewhat glitchy if subtitles are enabled, and you enable

On error, this will disable --lavfi-complex, which will result in
whatever behavior.

The changes to path list options is basically getting rid of the need to
pass multiple paths to a single option. Instead, you can use the option
multiple times. The old behavior can be used by using the -set suffix
with the option.
Change some options to path lists. For example --script is now append by
default, and if you use --script-set, you need to use ":"/";" as
separator instead of ",".
--sub-paths/--audio-file-paths is a deprecated alias now, and will break
if the user tries to pass multiple paths to it. I'm assuming that if
these are used, most users will pass only 1 path anyway.
--opengl-shaders has more compatibility handling, since it's probably
rather common that users pass multiple options to it.
Also document all that in the manpage.
I'll probably regret this later, as it somewhat increases the complexity
of the option parser, rather than increasing it.

This affects options like --vf or --display-tags. These used a "*"
suffix to match all options starting with a specific name, and handled
the rest in the option parser. Change this to remove the "*" special
case, and require every option parser to declare a list of allowed
suffixes via m_option_type.actions.
The new way is conceptually simpler, because we don't have to account
for the "*" in a bunch of places anymore, and instead everything is
centrally handled in the CLI part of the option parser, where it's
actually needed.
It automatically enables suffixes like -add for a bunch of other
stringlist options.

This was an annoying option type. And still is. But at least it's on the
same level as m_option_type_print_fn now, and can probably cleaned up
further like it. Both types are for options that are only on the command
line, always have special handling (i.e. do something with them in
parse_commandline.c before passing them to the generic
m_config.c/m_option.c layers), and are m_options only for --list-options
and (oddly) the split_opt_silent() function.

Before this, options with co->data==NULL (i.e. no storage) were not
added to the bridge (except alias options). There are a few options
which might make sense to allow via the bridge ("profile" and
"include"). So allow them.
In command_init(), we merely remove the co->data check, the rest of the
diff is due to switching the if/else branches for convenience.
We also must explicitly error on M_PROPERTY_GET if co->data==NULL. All
other cases check it in some way.
Explicitly exclude options from the property bridge, which would be
added due this, and the result would be pointless.

All authors of the current code have agreed (as far as this commit
requires).
options.c/options.h will take more effort, because it contains all the
option declarations, and thus is touched extremely often.
m_option.c is technically still GPL, because of commit 2c82d5a1d85378dd0
(michael has agreed to LGPL, but only once the core of mpv is LGPL).
The geometry parsing code in m_option.c was originally by someone who
could not be reached. However, it was heavily rewritten anyway, and only
the syntax remains (i.e. not copyright-relevant).
parse_commandline.c contains a change by "adland" (commit 1d0ac71ae8ba),
who could not be reached - this this specific part is GPL only.
Fortunately, it matters only for DVD (and even then is more like a hack,
but whatever).
There are some other relevant changes, but they have all been reverted,
moved somewhere else, deleted, or replaced.

af_volume is deprecated, and so are its replaygain sub-options. To make
it possible to use replaygain without deprecated options (and of course
to make it available at all after af_volume is dropped), reintroduce
them as top-level options.
This also means that they are easily changeable at runtime by using them
as properties. Change the "volume" property to use the new update
mechanism as well.
We don't actually bother sharing the implementation between new and
deprecated mechanisms, as the deprecated one will simply be deleted.
For the from_dB() functions, we mention anders' copyright, although I'm
not sure if a mere formula is copyrightable. This will have to be
determined later.
This whole change is mostly untested. Our distributed human CI will take
care of it.

Also "announce" the plans to undeprecate it with changed semantics
later. The deprecation period is needed to warn script authors and
client API users (etc.) of the change.
This is done because everyone seems to expect --loop to loop the current
file, not the playlist. Even in cases when only 1 file is on the
playlist, the --loop-file semantics seem to be preferred.

Basically, see the example in input.rst.
This is better than the "old" vf-toggle method, because it doesn't
require the user to duplicate the filter string in mpv.conf and
input.conf.
Some aspects of this changes are untested, so enjoy your alpha testing.

Remove more stuff that was needed only for legacy suboptions.
One user-visible change is that parent-options like --tv are now not
visible anymore. They lead to a special error message when used before,
but now they're simply not part of the option list anymore.

Long planned. Leads to some sanity.
There still are some rather gross things. Especially g_groups is ugly,

I'm not sure if this option affects anything or if it's a placebo,
especially since the VO thread is now registered with MMCSS. Still, I
think --priority=high may have helped back when I used mplayer2 on a
netbook. It's also possible that encoding-mode users would want to set
--priority=idle.
Anyway, it was one of the last M_OPT_FIXED options, so fix that.

If one of the audio output format options is set, brually reinit the
audio chain.
Since the audio-channels property is still mapped to the deprecated
read-only property, "options/audio-channels" currently has to be used,
e.g. "cycle-values options/audio-channels 2 7.1".

With the merging of options and properties, the mpv_set_option()
function is close to being useless, and mpv_set_property() can be used
for everything instead. There are certain conflicts remaining, which are
explained in depth in the docs. For now, none of this should affect
existing code using the client API.
Make mpv_set_property() redirect to mpv_set_option() before
initialization.
Remove some options marked as M_OPT_FIXED. The "pause" and "speed"
options cannot be written anymore without the playloop being notified by
it, so the M_OPT_FIXED does nothing. For "vo-mmcss-profile", the problem
was lack of synchronization, which has been added. I'm not sure what the
problem was with "frames" - I think it was only marked as M_OPT_FIXED
because changing it during playback will have no effect. Except for
pause/speed, these changes are needed to make them writable as
properties after mpv_initialize().
Also replace all remaining uses of CONF_GLOBAL with M_OPT_FIXED.

Use the new mechanism, instead of wrapped properties. As usual, extend
the update handling to some options that were forgotten/neglected
before. Rename video_reset_aspect() to video_reset_params() to make it
more "general" (and we can amazingly include write access to
video-aspect as well in this).
