Support for getting (i)MDCT output multiplied by a constant scaling factor.
...
Scaling (i)MDCT output has no runtime overhead and can be used to improve
performance of audio codecs. All the changes are only needed in
'ff_mdct_init' function and slow down initialization a bit.

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.

Bug fix for crashes when SSE is used on unaligned arrays.

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

stackframe. Linux and glibc always ensure this to be true thus
this never affected Linux.
