Notably, BGR0, which is the only additional format listed as supported
by the texture mapper, results in broken colors. This is most likely not
a mpv issue, so the whitelist fulfils its purpose.

A user can barely do anything useful with it, and there are no users
which access these anyway, so private is better.

I think the previous code didn't consider the situation if the input
format was not any of the upload formats. It then could have possibly
tried to upload the wrong format (and not sure what the underlying APIs
do with it).
Take care of this, also improve logging, and change it such that
mp_hwupload_find_upload_format() does not unnecessarily change the state
(although it doesn't really matter).

(Oh yes, we could have skipped all the complexity, and hardcoded the
cases that work in the first place. This wouldn't be an issue if FFmpeg
or libva exported correct information. Also possible that FFmpeg's
filter chain does not allow to do this correctly in the first place,
since filters expose next to no meta information about what hw formats
etc. they need.)
Note that uploading yuv420p to a nv12 vaapi surface actually works, but
the blacklist excludes it. So this might get a bit slower. I'm not
bothering with this case because it's rarely needed, and the blacklist
specification would become a bit more complex if you had to specify
sw/upload format pairs.
Fixes: #7350

Basically, instead of trusting the upload format, and picking the first
sw format that has a desired upload format, trust the sw format. So now
we pick the sw format first, and then select from the set of upload
formats supported by it.
This is probably more straightforward, and works around a crash with
vaapi:
mpv 8bit.mkv --vf=format=vaapi --gpu-hwdec-interop=all
(Forces vaapi upload if hw decoding is not enabled.)
Unfortunately, this still does not work, because vaapi, FFmpeg, the VO
interop code, or all of them are doing something stupid. In particular,
this picks the yuv420p sw format, which doesn't really exist despiter
advertised (???????????????????????????????????????), and simply breaks.

This just wraps the mp_image_hw_download() function as a filter and adds
some minor caching/error logging. (Shame that it needs to much
boilerplate, I guess.)
Will be used by the following commit. Wrapping it as filter seemed more
convenient than other choices.

This also switches the order, because that makes more sense.

Jesus Christ, how did I get this wrong, or never verified proper
function. This fixes --vf=vdpaupp not working with yuv420p input.

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.
