wm4 801fa486b0 ad_lavc, vd_lavc: move mpv->lavc decoder parameter setup to common code
This can be useful in other contexts.

Note that we end up setting AVCodecContext.width/height instead of
coded_width/coded_height now. AVCodecParameters can't set coded_width,
but this is probably more correct anyway.

wm4 c06fd19d8f av_common: drop unused function
Unused since the AVCodecParameters change.

wm4 3eceac2eab Remove compatibility things
Possible with bumped FFmpeg/Libav.

These are just the simple cases.

wm4 139f6b5de7 ad_lavc, vd_lavc: fix a recent libavcodec deprecation warning
Both AVFrame.pts and AVFrame.pkt_pts have existed for a long time. Until
now, decoders always returned the pts via the pkt_pts field, while the
pts field was used for encoding and libavfilter only. Recently, pkt_pts
was deprecated, and pts was switched to always carry the pts.

This means we have to be careful not to accidentally use the wrong
field, depending on the libavcodec version. We have to explicitly check
the version numbers. Of course the version numbers are completely
idiotic, because idiotically the pkg-config and library names are the
same for FFmpeg and Libav, so we have to deal with this explicitly as
well.

wm4 05e4df3f0c video/audio: always provide "proper" timestamps to libavcodec
Instead of passing through double float timestamps opaquely, pass real
timestamps. Do so by always setting a valid timebase on the
AVCodecContext for audio and video decoding.

Specifically try not to round timestamps to a too coarse timebase, which
could round off small adjustments to timestamps (such as for start time
rebasing or demux_timeline). If the timebase is considered too coarse,
make it finer.

This gets rid of the need to do this specifically for some hardware
decoding wrapper. The old method of passing through double timestamps
was also a bit questionable. While libavcodec is not supposed to
interpret timestamps at all if no timebase is provided, it was
needlessly tricky. Also, it actually does compare them with
AV_NOPTS_VALUE. This change will probably also reduce confusion in the
future.

wm4 c971220cdd demux_lavf, ad_lavc, ad_spdif, vd_lavc: handle FFmpeg codecpar API change
AVFormatContext.codec is deprecated now, and you're supposed to use
AVFormatContext.codecpar instead.

Handle this for all of the normal playback code.

Encoding mode isn't touched.

wm4 33774e18ed command: add encoder-list property
Also change decoder-list (for the sake of sharing the underlying code
for both properties).

wm4 8a9b64329c Relicense some non-MPlayer source files to LGPL 2.1 or later
This covers source files which were added in mplayer2 and mpv times
only, and where all code is covered by LGPL relicensing agreements.

There are probably more files to which this applies, but I'm being
conservative here.

A file named ao_sdl.c exists in MPlayer too, but the mpv one is a
complete rewrite, and was added some time after the original ao_sdl.c
was removed. The same applies to vo_sdl.c, for which the SDL2 API is
radically different in addition (MPlayer supports SDL 1.2 only).

common.c contains only code written by me. But common.h is a strange
case: although it originally was named mp_common.h and exists in MPlayer
too, by now it contains only definitions written by uau and me. The
exceptions are the CONTROL_ defines - thus not changing the license of
common.h yet.

codec_tags.c contained once large tables generated from MPlayer's
codecs.conf, but all of these tables were removed.

From demux_playlist.c I'm removing a code fragment from someone who was
not asked; this probably could be done later (see commit 15dccc37).

misc.c is a bit complicated to reason about (it was split off mplayer.c
and thus contains random functions out of this file), but actually all
functions have been added post-MPlayer. Except get_relative_time(),
which was written by uau, but looks similar to 3 different versions of
something similar in each of the Unix/win32/OSX timer source files. I'm
not sure what that means in regards to copyright, so I've just moved it
into another still-GPL source file for now.

screenshot.c once had some minor parts of MPlayer's vf_screenshot.c, but
they're all gone.

wm4 0f4bf347c5 player: print used number of threads in verbose mode
Also, don't use av_log() for mpv output.

wm4 d68a759fa4 Improve setting AVOptions
Use OPT_KEYVALUELIST() for all places where AVOptions are directly set
from mpv command line options. This allows escaping values, better
diagnostics (also no more "pal"), and somehow reduces code size.

Remove the old crappy option parser (av_opts.c).

wm4 26d973ce82 stream_lavf: allow setting AVOptions with --stream-lavf-o
This commit also creates a private option struct for stream_lavf.c, but
since I'm lazy, I'm not moving any existing options to it.
