ff_h264_decode_mb_cabac() and ff_h264_decode_mb_cavlc() are very long
functions. Declaring decode_chroma as const makes it clear the variable
doesn't change after initialization.

hevc_await_progress() uses the variable |y| only inside the "if" block.
So |y| only needs to be declared and initialized in that block.

This file already has #include "idctdsp.h", which is resolved to the
idctdsp.h header in the directory where this file resides by compilers.
Two other files in this directory, libavcodec/x86/idctdsp_init.c and
libavcodec/x86/xvididct_init.c, also rely on #include "idctdsp.h"
working this way.

For the blue and violet noise, I took the pink and brown noise
respectively and subtracted the offsets instead of adding them. When I
eyeball the frequency spectrum of the resulting outputs it looks correct
to me, i.e. the blue graph appears to be a mirror image of the pink, and
the same can be said of the violet and the brown. I did not do anything
else to confirm the correctness.
Also remove pthread_cond_broadcast(progress_cond) on uninit.
Broadcasting it is not required because workers are always
parked when they are not in thread_execute. So it is imposible
that a worker is waiting on progress_cond when uninitialized.

Rework it to improve performance. Now mutex is not shared by workers,
instead each worker has its own mutex and condition variable. This
reduces lock contention between workers. Also use atomic variable for
counter.
The interface also allows execute to run special function on main
thread, requested by Ronald.

Muxers may want to directly access filename in stored in
AVFormatContext. For example in case of RTSP, the filename (url)
is used by the muxer to extract parameters of the connection.
These muxers will fail when used with fifo pseudo-muxer.
This commit fixes this issue by passing filename from AVFormatContext
of fifo pseudo-muxer to all AVFormatContext(s) of underlying muxers
during initialization.

This makes probing for regular DTS more strict because more header
fields are checked and values not supported by decoder are now rejected.
Also fixes an issue original code had with 14-bit streams: 96 bits of
header were expected, however only 84 bits were converted, which was not
enough to parse LFE flag.

There are 3 different places where DCA core frame header is parsed:
decoder, parser and demuxer. Each one uses ad-hoc code. Add common core
frame header parsing function that will be used in all places.
