This implementation has the following issues:
1) pthreads implementation only -- we still need a windows version.
2) must investigate thread cancelation issues
3) Error reporting is very poor. I followed the error reporting on
the existing thread safe code, but this should be re-visited and
improved.
Code is currently setup to use the new recursive R/W lock instead of
the global mutex to control entry to the library in threadsafe builds.
To revert to the global mutex, set H5TS__USE_REC_RW_LOCK_FOR_GLOBAL_MUTEX
in H5TSprivate.h to FALSE.
Added a reasonably robust regression test for the reursive R/W lock
in test/ttsafe_rec_rw_lock.c
Note that the change to hl/src/H5LTanalyse.c is an artifact of clang-format.
Tested serial threadsafe debug and production on jelly, and also regular
serial / debug.
On Windows builds, the new recursive R/W lock should not be built and
we should use the existing global mutex -- however this is not tested
at this time.
