WMA: use type punning and unroll loops in decode_exp_vlc()
...
GCC does stupid things if these assignments are done using floats
directly, so fill the runs using integer operations instead. Also
unroll the loops since the length is always a multiple of 4.

The src3 and step arguments to vector_fmul_add_add() are always zero
and one, respectively. This removes these arguments from the function,
simplifies the code accordingly, and renames the function to better
match the new operation.

Scaling (i)MDCT output has no runtime overhead and can be used to improve

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.

No measureable change in speed. This gave random crashes on Win32
