Change various code to use the latest Libav API. The libavcodec
error_recognition setting has been removed and replaced with different
semantics. I removed the "--lavdopts=er=<value>" option accordingly,
as I don't think it's widely enough used to be worth attempting to
emulate the old option semantics using the new API. A new option with
the new semantics can be added later if needed.
Libav dropped APIs that were necessary with all Libav versions
until quite recently (like setting avctx->age), and it would thus not
be possible to keep compatibility with previous Libav versions without
adding workarounds. The new APIs also had some bugs/limitations in the
recent Libav release 0.8, and it would not work fully (at least some
avcodec options would not be set correctly). Because of those issues,
this commit makes no attempt to maintain compatibility with anything
but the latest Libav git head. Hopefully the required fixes and
improvements will be included in a following Libav point release.

Require versions of the Libav libraries corresponding to Libav release
0.7. These are:
libavutil 51.7.0
libavcodec 53.5.0
libavformat 53.2.0
libswscale 2.0.0
libpostproc 52.0.0
Also disable the fallback to simple header check if these libraries
could not be found with pkg-config; now compiling without pkg-config
support for these always requires explicitly setting --enable-libav
and any needed compiler/linker flags. The simple check would have let
compilation proceed even if a version mismatch was detected.

Previously the core sent VFCTRL_REDRAW_OSD to change OSD contents over
the current frame. Change this to VFCTRL_REDRAW_FRAME followed by
normal EOSD and OSD drawing calls, then vo_flip_page(). The new
version supports changing EOSD contents for libass-rendered subtitles
and simplifies the redraw support code needed per VO. vo_xv doesn't
support EOSD changes because it relies on vf_ass to render EOSD
contents earlier in the filter chain.
vo_xv logic is additionally simplified because the previous commit
removed the need to track the status of current and next images
separately (now each frame is guaranteed to become "visible" soon
after we receive it as "next", with no VO code running in the interval
between).

Libass has its own BiDi handling now, and preprocessing the subtitles
with FriBiDi before passing them to libass breaks things. Disable our
own FriBiDi code when libass rendering is used. This affects external
subtitle files of other formats parsed with subreader.c and converted
to ASS tracks.

Set the "Style" attribute for subtitle events created in sd_ass to
match the "default_style" attribute of the track. This is required to
make --ass-styles work with recent libass versions (otherwise the
event would use style 0, which is a fallback style added by libass
now).
Commit 378ada847c8eb3a641392691b1a2317f8fc214e0 ("sub/ass: use default
style, not first style unconditionally") fixed the same issue for
external subtitles converted with mp_ass_read_subdata(); this commit
fixes it for muxed ones.

Previously the code converting text subtitles to ASS format converted
newline characters, and only those, to ASS "new line" markup. If the
subtitles contained "\r\n", the "\r" was thus left in the text. In
previous libass versions the "\r" was not visible, but in the current
one it produces an empty box. Improve the conversion to remove the
"\r" in that case. Also treat a lone "\r" as a newline.

Remove unnecessary demuxer.h include from aviheader.h. Through
stheader.h aviheader.h is included in a lot of files. Add missing
mp_msg.h includes to av_sub.c and sd_ass.c (previously hidden by
indirect inclusion through demuxer.h and stream.h).

The OSD text buffers (mp_osd_msg_t.text and osd_state.text) used to be
static arrays, with the buffer sizes spread all over the code as magic
constants. Make the buffers dynamically allocated and remove the
arbitrary length limits.

Libass rendering uses two renderer objects to support both VSFilter
aspect ratio (mis)behavior emulation and correct rendering. When
option values were changed during playback the changes were applied to
the renderer used for the currently active track only, and old values
could be used if the user then switched to a track using the other
renderer object. Fix to update both renderers.

When libass-related options were changed at runtime, the
reinitilization code executed ass_set_margins() with arguments that
were correct for the vf_ass case but wrong for EOSD. This could cause
the subtitles to be displayed incorrectly for one frame (vf_vo would
run ass_set_margins() again with the correct parameters for the next
frame). The call is actually redundant for the vf_ass case too as
it's currently not possible to modify the margins during playback, so
fix the problem by disabling the call.

Rename the BSTR() function to bstr(). The former caused a conflict
with some Windows OS name, and it's no longer a macro so uppercase
naming is less appropriate.

The --ass-force-style option was only applied when the main libass
library handle was created. Thus any per-file option changes later had
no effect. Do the ass_set_style_overrides() call in per-file
initialization instead so that possible changes will be applied. Also
move the option variable to the option struct.
Current libass will crash (usually) if you set style overrides to a
nonempty value, then an empty one. It'll be easier to trigger this bug
after this commit, but the problem is not on mplayer2 side. The fix is
trivial so hopefully there will be a fixed libass soon.

Do the global initialization of libavcodec and libavformat
(avcodec_register_all(), av_register_all()) immediately on program
startup and remove the initialization calls from various individual
modules that use libavcodec/libavformat functionality.

Turns out it's a bad idea to just always unconditionally use the first
style. Make mplayer2 use and set the style according to the track's
default_style property. Fixes the -ass-styles option broken with
recent libass versions (ticket #40).

Fix artefacts at right border of scaled bitmap subtitles by clearing
the destination to 0 first if the width is not a multiple of 8.
This is necessary because some of the optimized sub drawing functions
always draw pixels in multiples of 8, so we cannot rely on any "dirt"
in the "unused" borders being ignored.
Note that due to the way rendering works, both alpha and the image need
to be cleared.

Commit a2d28010cc ("cleanup: find_subfiles.c: simplify (mainly using
bstr)") was missing a bstrdup() in subtitle search code, and thus the
code erroneously modified the original filename string passed in. As a
result anything which printed or otherwise used the filename after
that would use a lowercase-converted version instead of the actual
file name. Fix by adding the bstrdup() to operate on a local copy of
the name instead.

Also clarify compare_sub_priority() and remove a typedef for the subfn
structure in the process.

Also simplify subtitle selection a bit.

A file with the ambiguous extension .sub could be either VOBsub or
MicroDVD. If there's a corresponding .idx file it's certainly VOBsub,
so don't add it to the list of potential text subtitles. This will
avoid the annoying warning "SUB: Could not determine file format".

Analogously to the previous commit, move path handling logic for
loading external vobsub files from mplayer.c to find_subfiles.c.
Based on a commit from Clément Bœsch but fixed and simplified.

Move path handling for loading external subtitle files from mplayer.c
to find_subfiles.c. Now the remaining code in mplayer.c only gets a
list of potential filenames and tries opening those.

Move sub_filenames() and related code from subreader.c to new file
find_subfiles.c. This function is used to find subtitle files that
should be loaded for the current video; this functionality is not
specific to the particular kind of text subtitle handling implemented
in subreader.c.
Also reindent and prettify the moved code a bit.

There is no reason to use manual language list splitting when an
automatic split function is already available.
Some types change from "unsigned char" to "char", but this shouldn't
cause issues since [as]lang settings are unlikely to have characters
above 127.

Add new stream_read_complete() function which reads the complete
contents of file. Use that in ass_mp.c which had custom code to do the
same.

Do not pointlessly cast the return value of memalign().
memalign() returns void*, which is compatible with any pointer in C.

The various ass_* functions were created when libass was part of the
MPlayer tree and the distinction between MPlayer-specific and other
functions was less clear. Now that libass is a clearly separate
library, using the same ass_* namespace for player functions is ugly.
Rename the functions to use mp_ass_ prefix instead.

Rendering of ASS subtitles tries to be bug compatible with VSFilter
and stretches fonts when the video is anamorphic (some scripts try to
compensate for this VSFilter behavior, so trying to render them
"correctly" would give the wrong result). However this behavior is not
appropriate for subtitles we converted to ASS format ourselves for
libass rendering, as they certainly don't have VSFilter bug
workarounds. Change the code to use different behavior for "native"
ASS tracks and converted ones. It's questionable whether the
VSFilter-compatible behavior is appropriate for external .ass files
either, as there could be anamorphic and non-anamorphic versions of
the same video and the bug-compatible behavior can only be correct for
one alternative at most. However it's probably better to keep it as a
default at least, so that extracting a muxed subtitle track and using
that does not give behavior different from the original muxed one.
The aspect ratio setting is per ASS_Renderer, and changing it resets
libass caches. For that reason this commit adds separate renderer
instances to use for the "correct" and "VSFilter bug compatible"
cases.

Originally, when rendering plaintext subs with libass, the subtitles
were first converted to the "struct subtitle" form with sub_add_text()
and then from that to libass events. Change sd_ass to convert the
subtitles directly to libass events without using the old sub
machinery. The new conversion at least fixes some timing issues. Also
use the markup support added in the previous commit, so that
HTML-style markup is also supported in "plaintext" subs rendered with
libass.

SubRip subtitles have no "official" spec for any styling support, but
various tags are in common use; previous code filtered out text
between <> to remove HTML-style tags. Add support for those tags and
for MicroDVD subtitle styling. The style display is implemented by
converting the subtitles to the ASS subtitle format and displaying
them with libass, so libass needs to be enabled.
Original patch by Clément Bœsch <ubitux@gmail.com>.

Add a framework for subtitle decoder modules that work more like
audio/video decoders do, and change libass rendering of demuxed
subtitles to use the new framework.
The old subtitle code is messy, with details specific to handling
particular subtitle types spread over high-level code. This should
make it easier to clean things up and fix some bugs/limitations.
