f267d3ac75 Implement alpha channel decoding for BGR HuffYUV.
Since BGR24 is decoded as BGR32, fill its alpha channel with 255
using the appropriate predictors.

2ba8301769 Mark all pix_fmts and supported_framerates compound literals as const.
Makes no difference for gcc but at least icc can put them in .rodata then.

fdb699de62 Fix passing of unaligned addresses to dsputil diff_bytes() by
changeing calls to sub_left_prediction such that
the source frame data pointers are no longer offset to skip the initial
elements. This keeps them properly aligned for the subsequent call to diff_bytes.
Changes encoding offset to compensate.

aa5cfdfb4f Add offset argument to encode_422_bitstream() to control where
in the source data array to start encoding.
Change all calls to pass zero for this new argument for equivalent behavior.

This is a restructure to support a forthcoming bug fix.

7a00bbad21 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.

dd1c8f3e6e Bump Major version, this commit is almost just renaming bits_per_sample to
bits_per_coded_sample but that cannot be done seperately.
Patch by Luca Abeni
Also reset the minor version and fix the forgotton change to libfaad.
Note: The API/ABI should not be considered stable yet, there still may
be a change done here or there if some developer has some cleanup ideas and
patches!
