7a00bbad21 Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an

flag, which appears necessary to playback corePNG P-frames.

e7a6d5f313 Bug fix for crashes when SSE is used on unaligned arrays.
No measureable change in speed. This gave random crashes on Win32
and BeOS. The cause for this bug is that gcc doesn't align the
stackframe. Linux and glibc always ensure this to be true thus
this never affected Linux.
