Details: - Added the blas2blis compatibility layer, located in frame/compat. This includes virtually all of the BLAS, including banded and packed level-2 operations. - Defined bl2_init_safe(), bl2_finalize_safe(). The former allows a conditional initialization, which stores the "exit status" in an err_t, which is then read by the latter function to determine whether finalization should actually take place. - Added calls to bl2_init_safe(), bl2_finalize_safe() to all level-2 and level-3 BLAS-like wrappers. - Added configuration option to instruct BLIS to remain initialized whenever it automatically initializes itself (via bl2_init_safe()), until/unless the application code explicitly calls bl2_finalize(). - Added INSERT_GENTFUNC* and INSERT_GENTPROT* macros to facilitate type templatization of blas2blis wrappers. - Defined level-0 scalar macro bl2_??swaps(). - Defined level-1v operation bl2_swapv(). - Defined some "Fortran" types to bl2_type_defs.h for use with BLAS wrappers.
