Ronald S. Bultje 3e13005cac mp3on4: require a minimum framesize. 
If bufsize < headersize, init_get_bits() will be called with a negative
number, causing it to fail and any subsequent call to get_bits() will
crash because it reads from a NULL pointer.

Ronald S. Bultje b4027d9749 wmapro: change max. block size to 13 bits. 
WMApro actually support 13-bits block sizes (potentially even up to 14),
and thus we should support that also. If we get block sizes beyond what
the decoder can handle (14 is possible depending on s->decode_flags),
error out instead of crashing.

Michael Niedermayer 204cb29b3c shorten: Use separate pointers for the allocated memory for decoded samples. 
Fixes invalid free() if any of the buffers are not allocated due to either

Justin Ruggles f320fb894c bethsoftvid: pass palette in side data instead of in a separate packet. 
Update FATE reference to account for now non-existent palette packet.
This also fixes the FATE test if frame data is not initialized in
get_buffer(), so update comment in avconv accordingly.

Christophe GISQUET f3e084909b mpegaudio: replace memcpy by SIMD code 
By replacing memcpy with an unrolled loop using the alignment knowledge
it has, some speedup can be obtained.

Before (gcc 4.6.1): ~400 cycles
After: ~370 cycles

Overall, around 2% speed increase when decoding a 2400s mp3 to f32le.
