<nielkie@gmail.com>, done for GCI 2010. Same output as the original

The code is based on the remove-logo filter in MPlayer/libmpcodecs, by
Robert Edele, relicensed to LGPL with consent of the author.
Address trac issue #249.
Since the mandatory memcpy in vsrc_buffer has been eliminated, there
shouldn't be any significant reason to build without lavfi anymore.
This will make upcoming support for complex filtergraphs easier to do.

The previous implementation assumed that a new picture would always
supersede the previous picture. Similarly, presentation segments
were assumed to pertain to the most-recently-read picture.
However, each presentation segment may refer to 0 or more pictures
by their ID. Picture IDs may repeat, and a repeated picture ID
indicates that the old picture for that ID is no longer needed
and may be discarded.
The new implementation allocates a buffer with one slot for each
possible picture ID (the picture ID is a 16-bit field) and
properly decodes presentation segments so that all relevant
pictures are output upon encountering a display segment.
Given that most PGS streams are unlikely to use more than a small
fraction of the available picture IDs, it would probably be better
to use a more memory-efficient data structure. I'm lazy though, so
I leave this to a more motivated individual.
I've tested the code with MKV files in VLC (a recent revision from
their git repo) and with HandBrake (a version that I hacked up to
use ffmpeg's PGS subtitle decoder).

The WAVE demuxer returns packets with many blocks per frame, which needs to be
parsed into single blocks. This has a side-effect of fixing the timestamps.
Add -show_frames option to ffprobe.
Partially based on the work of Thomas Kuehnel <kuehnelth@googlemail.com>
for SOCIS 2011.
The wicked idea of creating a special "packets_and_frames" container for
structured formats (JSON and XML) comes from Clément.

Possibly the decoder could accept the header as extradata to simplify

FFmpeg never had distinct alfa/beta 0.7 releases, so having a single
0.8 section with all the changes should be less confusing for the
users, and it is also consistent with what we did with 0.5 and 0.6
releases.
Also add a dedicated 0.7 section, explaining how it differs from 0.8.
