Use static mutexes instead of requiring a lock manager. The behavior
should be roughly the same before and after this change for API users
which did not set the lock manager at all (except that a minor memory
leak disappears).
Purpose: libavutil/thread.h: Fixed g++ build error when ASSERT_LEVEL
is greater than 1. This is only relevant when thread.h is included by
C++ files. In this case, the relevant code is only defined if
HAVE_PTHREADS is defined as 1. Use configure --assert-level=2 to do
so.
Note: Issue discovered as a result of Coverity build failure. Cause
of build failure pinpointed by Hendrik Leppkes.
Comments:
-- libavutil/thread.h: Altered ASSERT_PTHREAD_NORET definition such
that it uses av_make_error_string instead of av_err2str().
av_err2str() uses a "parenthesized type followed by an initializer
list", which is apparently not valid C++. This issue started
occurring because thread.h is now included by the DeckLink C++
files. The alteration does the equivalent of what av_err2str()
does, but instead declares the character buffer as a local
variable.

USE_ATOMICS is only set if there is no thread implementation enabled, in
which case you can't expect any lock mechanism from FFmpeg.
This is also conflicting with the incoming use of stdatomic.
Also add no-op fallbacks when threading is disabled.
This helps keeping the code clean if Libav is compiled for targets
without threading. Since we assume that no threads of any kind are used
in such configurations, doing nothing is ok by definition.
Based on a patch by wm4 <nfxjfg@googlemail.com>.
This allows writing most code as if they always are is available.
These are ok to use from other libraries even though it's not a
public header, since they only provide an inline declaration, and
doesn't add an actual dependency on lavu internals. (This can be
considered more a build system compatibility fallback than a
libavutil feature.)

This reduces the number of false dependencies on header files and
speeds up compilation.

Otherwise doxygen complains about ambiguous filenames when files exist
under the same name in different subdirectories.

Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.' to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".

while playing with some new hardware, I found it's running a forked mplayer
-- and it looks like they're following the GPL.
The maintainer's page is here: http://atty.jp/?Zaurus/mplayer
Unfortunately it's mostly in Japanese, so it's hard to figure out any
details.
Their code looks quite interesting (at least to those of us w/ ARM CPUs).
The patches I've attached are the patches from atty.jp with a couple of
modifications by myself:
- ported to current CVS
- reverted their change of removing SNOW support from ffmpeg
- cleaned up their bswap mess
- removed DOS-style linebreaks from various files
