Drop ALT_ prefix from BITSTREAM_READER_LE name.

The prefix is a historic remnant that probably meant "alternative".
Now that the A32 bitstream reader has been dropped it makes no sense anymore.

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.

"Google Summer of Code participation" on the mailinglist.
