5b8009f4c8 apedec: do not keep incrementing the input data pointer past the end of the
buffer during entropy decoding.

The pointer address could overflow, which would likely segfault. Instead set
the context error flag to indicate that the decoder tried to read past the
end of the packet data.

fd244ae3a0 apedec: use unsigned int for offset

b7e5145759 apedec: do not set s->samples until after validation.
This prevents errors and/or invalid writes in the next decode call due to
s->samples still being negative.

21a19b7912 doxygen: Prefer member groups over grouping into modules
Before this, almost all module groups have been used for grouping functions
and fields in structures semantically. This causes them to not appear
properly in the file documentation and needlessly clutters up the "Modules"
index.

Additionally, this commit streamlines some spelling and appearances.

737eb5976f Merge libavcore into libavutil
It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

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.

6a287b739f Detect and prevent reading over the end of counts_*. We pass the error
through a context variable as this is simpler and i think also faster, but
the return value of functions could be used instead of course.
The code also ensures as a side effect that the AC decoder state does not
become invalid.
This fixes all known crashes. And outputs nothing in case of an error instead
of random noise.
