547c2f002a Make decoding alpha optional for some codecs. 
For codecs where decoding of a whole plane can simply
be skipped, we should offer applications to not decode
alpha for better performance (ca. 30% less CPU usage
and 40% reduced memory bandwidth).
It also means applications do not need to implement support
(even if it is rather simple) for YUVA formats in order to be
able to play these files.

2aa8e33d7d Fix nonsense MPEG-4 hwaccel code. 
Issues with the code:
1) The skip_bits_long breaks packed B-frames since we skip
of the packed frame, even for VDPAU.
2) Calling ff_h263_find_resync_marker_reverse is nonsense for MPEG-4,
and for H.263 the only code using this (vaapi_mpeg4) explicitly reverts
this change!
3) mb_x/mb_y are always 0 when vaapi_mpeg4_decode_slice, so doing
computations with them is just obfuscation
4) due to not updating mb_y the code would always go into the error
resilience case, causing nonsense error messages and maybe further
issues.

While tested to fix the data provided to the decoder in case of
VDPAU so it is the same as for the non-hwaccel code, the VA-API code
was not tested to still work, and adding regression testing even
as a quick hack is much more complicated for it.

a different than stated number of element can be present.

e07ac727c1 avcodec/g2meet: Fix framebuf size 
Currently the code can in some cases draw tiles that hang outside the
allocated buffer. This patch increases the buffer size to avoid out
of array accesses. An alternative would be to fail if such tiles are
encountered.
I do not know if any valid files use such hanging tiles.
