417db39d0d codecparsers: mpeg4: actually return full number of bits of resync marker
Switch the increment of markersize from when it is used to when it is
returned from compute_resync_marker_size.

This also makes the CHECK_REMAINING in gst_mpeg4_parse_video_packet_header
check for the actually required number of bits now and not one too few.

b14fb383ed Revert "codecparsers: remove ignored increment of return"
This reverts commit 916b954315.

Clearly something else was intended, and it also makes
more sense to add the extra bit. The resync marker is
N zero bits plus a 1 bit, and the pattern/mask needs to
be run on N+1 bits too.

(Even after the rever the code doesn't do that of course, so
it still needs to be fixed differently.)

916b954315 codecparsers: remove ignored increment of return
'return val++;' returns the value before it is incremented because the post
increment happens after the statement. Removing the unused increment.

2f28fcb862 parser: mpeg4: fix vlc table used for sprite trajectory
The vlc table members cbits, cword and values were assigned in the wrong
order, causing the mpeg4 parser to fail when handling sprite
trajectories.

5196f24138 codecparsers: add C++ guards for MPEG-4 and VP8 parsers.
Fix MPEG-4 and VP8 APIs to export their external symbols as pure C
symbols, i.e. un-mangled for C++.

20669d461a Fix 'ignoring return value of function declared with const attribute'
This always happens with GstByteReader/Writer and friends when
not taking into account returned boolean of the _read/_write functions
(which is actually wrong).

Make use of the *_unchecked variant as much as possible, or take the
returned value into account.

12c678c7cf codecparsers: minor fixes
Const-ify one more VLC table. Fix spelling of 'hybrid'.
No need to explicitly call ensure_debug_category() everywhere,
that will be done automatically from GST_LOG() and friends
via GST_CAT_DEFAULT.
