7651c0e49b Avoid overflows when reading pgm files with maxval != 255 and != 65535. 
libjpeg v6b apparently does not initialize the most significant bits
to zero when writing 12bit pgm's with maxval 4095.

54ba52077c arm: Comment out unused labels in simple_idct_arm 
When building for iOS in thumb mode, gas-preprocessor.pl doesn't
mark unused labels as thumb functions (as it does for other
local labels, where it can figure out that they are functions
due to being referenced in branch instructions). This leads to
linker warnings for some of those local labels, such as:

ld: warning: ARM function not 4-byte aligned: __a_evaluation from
libavcodec/libavcodec.a(simple_idct_arm.o)

Therefore, comment them out since they don't have any function.
They do still have a value in documenting key points in the
assembly source though.

4719040cd1 libx264: Define X264_API_IMPORTS on MSVC/ICL 
libx264 has a few data exports which require X264_API_IMPORTS
to be defined if we link to libx264 dynamically on Windows.

In a similar fashion to how we handle our compat snprintf
implementation, if we define it all the time, the compiler
will first try and link to __imp_x264_symbol_name, and failing
that, as in the case of a static libx264, will attempt to link
to the non-prefixed symbol, which has already been pulled in by
other x264 functions' object files.

8f24c12be7 ac3dec: Don't consume more data than the actual input packet size 
This was handled properly in the normal return case at the end
of the function, but not in this special case.

Returning a value larger than the input packet size can cause
problems for certain library users.

Returning the actual input buffer size unconditionally, since
it is not guaranteed that frame_size is set to a sensible
value at this point.

  indeo: Bound-check before applying motion compensation

The added checks and one previously added check are replaced by asserts,
the conditions can only be
true when vectors are invalid or there are worse inconsistencies.
We are checking the vectors validity and there should be no
inconsistencies, thus the checks should not be needed.
Also no files are known to cause any anomalies in ffmpeg

410066986f aic: use chroma scan tables while decoding luma component in progressive mode 
For some unclear reason Apple decided to use the same scan tables for luma and
chroma in the progressive mode while using different ones for luma in the
interlaced mode.

5efbeae38c configure: rename have_incompatible_fork_abi -> have_incompatible_libav_abi 
"Fork" is an ambiguous term, since there may be more than one fork, also
"fork" could be confused with the corresponding function. Also it seems
important to point the name of the referenced fork in the symbol.

Note: the old --enable-incompatible-fork-abi command is retained for
compatibility, although it should be considered deprecated.

The added condition is impossible to occur and thus is added to the assert.
The assert is not removed from the default case, as the default case cannot
occur. Thus either it should stay as is or the case as a whole be removed.
For extra safety, to ensure this doesnt change the assert is changed to
av_assert0()

3f54547709 utvideo: Add ULH0 and ULH2 decoding to the native decoder. 
Also prevents an error since the native decoder (if enabled) is
always used to probe Ut Video-encoded files, even if the user
forces libutvideo to be the decoder. Without this patch, the probe
would fail, and the video wouldn't get properly handed over,
resulting in failure to set codec parameters. When the native
decoder is disabled, libutvideo can probe and initialize decoding
without issues.
