e3c5395402 VP8: don't overread edges on fourtap MC.
Fix C VP8 H+V MC functions which do two-dimensional 4/6-tap filters to
not overread beyond their edges if the second filter is 4-tap, since
the outer pixels aren't there anymore since
44002d8323.

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

4b21c38180 Make ff_cmap_read_palette static to libavcodec/iff.c. Delete iff.h.
The iff.h header only declared one function that is now static, the
libavformat/iff.c source file wasn't using it before. Drop the file
entirely.

e732af87fc ac3: Remove ff_ac3_critical_band_size_tab.
It is only used to generate band_start_tab, which about the same size, at

11c7f64a9c Don't declare a pcm_dvd encoder.
The PCM_DVD encoder would be left unused, as allcodecs.c properly declared
it as being decoder-only, but it would still be built into the object file.

Since there is no block of code to properly encode this PCM format, it's
not a full codec.

990f213e57 Remove "libmpeg2" bitstream reader
Using the libmpeg2 reader causes errors in a multitude of places,
including MPEG and H264 codecs.  As the advantage of this reader
is questionable, removing it seems the sensible course of action,
especially considering the simplifications this allows elsewhere
with the bit cache size increasing from 17 to 25 bits as minimum.

This is also confirmed with Onkyo TX-SR607 receiver which recognizes

f14bdd8e75 H.264: Partially inline CABAC residual decoding
Improves CABAC performance about ~1.2%.

Trick originates from x264 and has also been used in ffvp8.  It's useful because
coded block flags are usually zero, so it helps to have the early termination
inlined into the main function.

The hunk is not fully understood but it just makes a check tighter so its
safer for us to apply until it is fully understood.

Might fix issue 2550 (and Chrome issue 68115 and unknown CERT issues).
Our bugtracker issue though should stay open until this has been fully
