libavutil/thread.h: Fixed g++ build error when ASSERT_LEVEL is greater than 1
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.
