b5fc571e4f latmdec: Check AudioSpecificConfig length before decoding extradata. 
This is different than a normal get_bits() over read because
decode_audio_specific_config() creates its own GetBitContext.

Fixes Bug 170.

e7d02b04dc fft: init functions with INIT_XMM/YMM. 
This is required to handle clobbering of XMM registers on Win64
correctly. Fixes FFT and all tests depending on FFT on Win64.

56f22b7e16 pcmenc: set frame_size to 0. 
This indicates that the actual frame size is based on the buf_size passed to
avcodec_encode_audio().

82390f57d1 avcodec: add GSM parser 
The WAVE demuxer returns packets with many blocks per frame, which needs to be
parsed into single blocks. This has a side-effect of fixing the timestamps.

3ab7700018 mpegvideo: claim ownership of referenced pictures 
Under certain conditions pictures could be released before they were
returned with frame-threading. Broken mv computation in the upcoming
rv34 frame-threading patch was caused by this.

To prevent contexts from running out of available pictures the loop
releasing "unused" pictures has to be run for B frames too.

17ce52912f aacsbr: prevent out of bounds memcpy(). 
Fixes Libav Bug 195.

This doesn't make the code handle sample rate or upsample/downsample
change properly but this is still a good sanity check.

Based on change by Michael Niedermayer.

1ef8ff4534 cabac: remove put_cabac_u/ueg from cabac-test. 
The functions are not used in any part of Libav, therefore testing them in the
cabac-test is unnecessary. Since this makes them unused, remove the functions.
