d7eabd5042 mpc: pad mpc_CC/SCF[] tables to allow for negative indices.
MPC8 allows indices of mpc_CC up to -1, and mpc_SCF up to -6, thus pad
the tables by that much on the left end.

c4f5c2d6f4 Move some mpegaudio functions to new mpegaudiodsp subsystem
This separation allows these functions to be used in a cleaner
fashion from other codecs (e.g. qdm2) and simplifies creating
optimised versions of them.

737eb5976f Merge libavcore into libavutil
It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

7d3829a87a Musepack SV8 supports "mono" files (though it still codes them as stereo),
so extend decoder to output only one channel for it.

This fixes issue 2368.

f3d77632d7 16l trocadero: Musepack SV7 decoder may skip more than 16 bits at the
beginning of the frame, so make it use skip_bits_long() instead of
skip_bits() for that.

76c4a644ee Fix an issue uncovered by commit 20623:
The init functions of mpc7 and mpc8 check whether the vlc has been
initialized already and return early if this is the case (eg by calling
init a second time).
But avctx->sample_fmt and channel_layout is set after the vlc initialization,
causing it not to be set on the second call of init.

Move all manipulations of avctx before the initialization of the vlc,
so that it is always set.

7a00bbad21 Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an
AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows
passing of packet-specific flags from demuxer to decoder, such as the keyframe
flag, which appears necessary to playback corePNG P-frames.

Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread
"Google Summer of Code participation" on the mailinglist.
