Added Fortran APIs for some thread functions.

Browse Source 
Details:
- Defined Fortran-77 compatible APIs for bli_thread_set_num_threads()
  and bli_thread_set_ways(). These wrappers are defined in
  frame/compat/blis/thread/b77_thread.c. Thanks to Kay Dewhurst for
  suggesting these new interfaces.
- Added missing prototype for bli_thread_set_ways() in bli_thread.h and
  removed prototypes for non-existent functions bli_thread_set_*_nt().
- CREDITS file update.
