a4a750d3b2 Rename alloc_picture to ff_alloc_picture and move its definition 
in mpegvideo.h to avoid including mpegvideo_common.h in mpeg12.c,
because it contains motion code.

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.

a4c7a5ea27 Call ff_fetch_timestamp() for mpeg1/2 when a picture start code is found instead 
of calling it at the end of a frame with a large negative offset.
This significantly reduces the maximal distance in container packets between
the point where the first byte of the "access unit" was stored and where
we call ff_fetch_timestamp() thus reducing the constraints on our parser.
Also change the parser from next_frame_offset to cur, this is needed
because now the reference is from container packet start instead of
frame start. (i previously misinterpreted this as bug)

987903826b Globally rename the header inclusion guard names. 
Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.'  to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".

4bdd3b76fe mpegvideo.h has two function declarations with the 'inline' specifier 
but no definition for those functions. The C standard requires a
definition to appear in the same translation unit for any function
declared with 'inline'. Most of the files including mpegvideo.h do not
define those functions. Fix this by removing the 'inline' specifiers
from the header.
