3048fae63c build: Avoid detecting bogus components named 'x' 
The function find_things() in configure is confused by component
registration calls as part of multiline macros defining combined
component registration.  Coalesce those macros into one line to
work around the issue.

9ac44ad9d0 h264: check SPS entries directly to detect pixel format changes 
Comparing AVCodecContext.pix_fmt against the get_pixel_format() return
value has the side effect of calling the get_format() callback on each
slice. Users of the callback will probably handle hardware accelerator
initialization in the callback.

It does not use any of the mpegvideo infrastructure, just a few fields
from the context.

Fixes a segfault with the emu edge flag, since emu edge buffer is now
allocated as a part of the frame buffer allocation and cavs calls
ff_get_buffer() directly, it does not use mpegvideo buffer management.

Fixes a memleak of the last frame.

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.

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.

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.

6f40e9f070 x86inc: support stack mem allocation and re-alignment in PROLOGUE 
Use this in VP8/H264-8bit loopfilter functions so they can be used if
there is no aligned stack (e.g. MSVC 32bit or ICC 10.x).

02823f6d71 Make LOCAL_ALIGNED syntactically similar on all systems 
This changes the LOCAL_ALIGNED definition on systems where
DECLARE_ALIGNED is used so it matches the manual alignment
case, ensuring invalid use will not compile on x86 only to
fail on everything else.

2ddf7c88d1 ZeroCodec: Flip output 
The initial testing of the VFW binary codec was flawed,
likely due to an AviSynth bug.

Re-testing using VirtualDub and various professional editing
applications has revealed it should have been flipped.

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.

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.
