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.

It should not be a value larger than the number of streams we have,
or it will cause invalid reads and/or SIGSEGV.

This seems to be non-optional, and if the muxer is run without it,
strlen() is run on NULL, causing a segfault.
