9adcccde0c mpegaudiodec, mpc and qdm2 all use the same mpa_synth window, so make 
them use the same variable/global storage.
Saves 4 kB in .bss.

686884da9d Use cbrtf and exp2f instead of pow to calculate tables for MPEG audio decoding. 
This hopefully is fast enough so that it is reasonable to use the same formula
directly instead of the table for CONFIG_SMALL.

822d0a6e0c Drop code that attempts to decode frames that are prefixed by junk. 
Too often it ends up decoding random data into noise without detecting
it (for example after seeking of some MP3 data with oddly often occurring
startcode emulation).
Fixes issue1154.

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.
