eb285cfe8e Fix avcodec_align_dimensions to return values suitably aligned for FLV decoding
with SSE and add a avcodec_align_dimensions2 taht returns the stride alignment
requirements independently from doing the width/height padding.

c4f267ab75 Free encoder extradata in avcodec_close(). Should fix several small memory
leaks when encoding (at least for asv, wma and aac).

Fix also issue 1577.

9df9b810c5 Handle more ADPCM codecs in av_get_bits_per_sample().
This removes some special-case code from riff.c.
CODEC_ID_ADPCM_G726 is still handled in riff.c as before because it is
not guaranteed to be fixed 4 bits per sample.

8d23a86f33 Add an execute2 function that is more flexible and allows to use parallel
processing with jobs > threads without wasting too much memory.
It also avoids needing a separate int array when the only additional data
the jobs needs is a single int running from 0 to count-1.

681c180dc4 Make avcodec_open set codec_id and codec_type if they haven't been set.
This fixes the API breakage introduced by the check that avctx codec id and type
match the opened codec and should make (almost?) all applications work again.

CorePNG delta frames.
CorePNG can not be correctly decoded via this old API either way.

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.

"Google Summer of Code participation" on the mailinglist.
