4c5e7b27d5 flacdec: fix buffer size checking in get_metadata_size() 
Adds an additional check before reading the next block header and avoids a
potential integer overflow when checking the metadata size against the
remaining buffer size.

ec6402b7c5 lavc: use designated initialisers for all codecs. 
It's more readable and less prone to breakage.

d36beb3f69 Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. 
None of these symbols should be accessed directly, so declare them as
hidden.

4c1645a458 Set sample format in flac_decode_init() rather than in 
ff_flac_parse_streaminfo() since the latter is shared with the raw FLAC

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.
