Uoti Urpala a43a4aafd0 configure, build: support compiling without libpostproc
libpostproc has been removed from Libav and the library now exists as
a separate project. Because it's not essential, separate it from the
Libav library check and allow compiling without it.

Uoti Urpala db8cdc73e3 Update Libav API uses
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.

Uoti Urpala 2e1cdcb9e6 configure, build: remove --disable-libav support
Remove support for building the player without libavcodec and
libavformat. These libraries are now always required.

Uoti Urpala 54d0763b92 av_log: don't crash if called with NULL AVClass
At least libavformat mpegts demuxer may give bad parameters with NULL
AVClass to the av_log callback. Check for this and print a warning
instead of crashing.

Uoti Urpala a4f4130819 cleanup: do libav* initialization on startup
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.

Uoti Urpala 1763fb5a56 av_log: map libav* debug messages to MSGL_DBG2
Map libav* messages with verbosity value higher than AV_LOG_VERBOSE
(likely to be AV_LOG_DEBUG) to MSGL_DBG2 instead of MSGL_V. Before
MSGL_V was used for everything above AV_LOG_INFO.

Uoti Urpala c33fafd6f1 Update libav API uses
Update various code to use newer alternatives instead of deprecated
functions/fields that are being dropped at libav API bump. An
exception is avcodec_thread_init() which is being dropped even though
it's still _necessary_ with fairly recent libav versions, so there's
no good alternative which would work with both those recent versions
and latest libavcodec. I think there are grounds to consider the drop
premature and revert it for now; if that doesn't happen I'll add a
version-test #if check around it later.

Uoti Urpala c5e462b33d build: enable/disable all FFmpeg libraries together
Enable all of libavcodec, libavformat, libswscale, and libpostproc
together (libavutil is always required).

Uoti Urpala 8bbb79c03a av_log callback handling overhaul
Move av_log callback handling from vd_ffmpeg.c to a new file
av_log.c and install the callback immediately when starting the
program. Main functionality improvements of the new code:

 - The old version only installed the callback when opening an FFmpeg
   video decoder. If nothing had triggered that then av_log() messages
   from other sources (libavformat, audio decoding, swscale usage)
   bypassed MPlayer's output system completely. Now the callback is
   always installed.

 - Current av_log message severity levels are handled correctly. The
   old code used MSGL_ERR for some messages that should be MSGL_V.

 - Message type is now set for libavformat contexts
   (MSGT_DEMUXER / MSGT_MUXER).

 - The old code did "mp_msg_test(type, mp_level)" before actually
   determining the type, so that it always used MSGT_FIXME. This led
   to some messages being incorrectly dropped in case the user
   had specified module-specific verbosity levels. The old check in
   question was originally motivated by performance problems when
   there were a lot of callbacks; however it's not clear whether the
   part about it skipping the type determination was intentional (most
   of the performance problems must have come from the way the
   original code used snprintf) and in my tests current FFmpeg
   libraries have not generated unreasonable amounts of callbacks
   anyway.
