0940580adb lavc: Correct the description of pkt_dts 
The description as updated in 6e5c44b0f made it sound like it is
handled exactly like the pts, which it is not. Clarify that it
is the packet that triggered returning the frame instead of just
the last avpacket (in case of frame threading, it won't be the
dts of the last packet).

3e15775333 x86/ac3dsp_init: try to workaround ICC failure. 
The asm code is not valid for older compilers as it uses too many
operands, ICC on x86_32 seems affected by this.
This patch disables the affected code for ICC on x86_32 and should
make it compileable again.
A better fix would be to use fewer operands or to change this code
to yasm, later is being worked on AFAIK so this is a temporary
solution.

5778299c7e ttadec: fix last frame handling when seeking 
Using a frame count, as is done currently, does not work at all with
seeking. Instead, when the number of samples in the final frame has
been decoded, we check if only the 32-bit CRC is remaining. If so, we
assume that it is the final frame.

There is no longer a need to keep total_frames in TTAContext.

Beginning with version 1.5.1 openjpeg defaults to install its headers to
/usr/include/openjpeg-${major}.${minor} instead of /usr/include without

Sometimes the extradata has duplicate atoms, but that shouldn't prevent
decoding. Just ensure that it is at least 36 bytes as a sanity check.

45635885e4 mpegvideo: increase edge_emu_buffer size for VC1 
The VC1 decoder uses edge_emu_buffer simultaneously for luma and chroma
and needs more space. That was not a problem before f1d8763a02
since the size for edge_emu_buffer was always calculated with 2 byte per
pixel since the linesize was not known.

Fixes occasionally fate errors in vc1_sa10143.

f1d8763a02 mpegvideo: allocate scratch buffers after linesize is known 
Since we can't know which stride a custom get_buffer() implementation is
going to use we have to allocate this scratch buffers after the linesize
is known. It was pretty safe for 8 bit per pixel pixel formats since we
always allocated memory for up to 16 bits per pixel. It broke hoever
with cmdutis.c's alloc_buffer() and high pixel bit depth since it
allocated larger edges than mpegvideo expected.

Fixes fuzzed sample nasa-8s2.ts_s244342.

9a2e79116d golomb: use unsigned arithmetics in svq3_get_ue_golomb() 
This prevents undefined behaviour of signed left shift if the coded
value is larger than 2^31. Large values are most likely invalid and
caused errors or by feeding random.

Validate every use of svq3_get_ue_golomb() and changed the place there
the return value was compared with negative numbers. dirac.c was clean,
fixed rv30 and svq3.

92dad6687f arm: fix use of uninitialised value in ff_fft_fixed_init_arm() 
When initialising an FFTContext for a plain FFT, mdct_bits is not set
and can contain a garbage value.  Since nbits is always valid and for
MDCT operation is mdct_bits - 2 checking this instead avoids using an
uninitialised value while having the same effect.

0393cf15db Revert "Acquire lock when initializing parsers." 
This reverts commit 7feef7dbca.

This commit causes assertion failures due to use of parser_init from multiple
threads, for example indirectly by ffmpeg.c and more directly from the
packet read functions.

I dont know how to fix this quickly, and fixing ffmpeg.c leaves
the possibility of other applications being affected.
Crashing the applications until this is resolved is clearly no good
thus this revert, so we have time to think about the problem.

Crashes can be reproduced by using multiple input files in ffmpeg.
