3ee8ca9b08 add avcodec_get_subtitle_defaults() to initialize AVSubtitle struct 
Call this new function before decode() to replace the custom and
inconsistant initialization in various decoders.
This function is equivalent to avcodec_get_frame_defaults() for AVFrame.

20708223db Do not fail DVB sub decoding because of a few padding bytes 
Instead of returning an error when bytes are left over, just return
the number of actually used bytes as other decoders do.
Instead add a special case so an error will be returned when none
of the data looks valid to avoid making debugging a pain.

52b2e95cd9 dvdsubdec.c: prevent input buffer overflow 
In some places, dvbsubdec passes improper input buffer size to
bitstream reading functions, not accounting for reading pointer
updates.

Fixed by using buffer_end - buffer pointer instead of fixed buffer length.

None of these symbols should be accessed directly, so declare them as

b834becdae Pass the composition and ancillary ID for DVB subtitles via extradata instead 
of sub_id, this allows detecting when that information is not available and
just decode everything.
In addition extradata is required for many codecs and thus in contrast to
sub_id generally already passed on by any programs using libav*.
Also ask for a sample if we encounter a stream with multiple/changing IDs.

29d7eef7dc Always allocate a buffer of AVPALETTE_SIZE for palette in the subtitle 
decoders instead of as small as possible.
This avoids completely unnecessary issues with e.g. libswscale.

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.
