Details: - Defined two new functions in bli_init.c: bli_init_once() and bli_finalize_once(). Each is implemented with pthread_once(), which guarantees that, among the threads that pass in the same pthread_once_t data structure, exactly one thread will execute a user-defined function. (Thus, there is now a runtime dependency against libpthread even when multithreading is not enabled at configure-time.) - Added calls to bli_init_once() to top-level user APIs for all computational operations as well as many other functions in BLIS to all but guarantee that BLIS will self-initialize through the normal use of its functions. - Rewrote and simplified bli_init() and bli_finalize() and related functions. - Added -lpthread to LDFLAGS in common.mk. - Modified the bli_init_auto()/_finalize_auto() functions used by the BLAS compatibility layer to take and return no arguments. (The previous API that tracked whether BLIS was initialized, and then only finalized if it was initialized in the same function, was too cute by half and borderline useless because by default BLIS stays initialized when auto-initialized via the compatibility layer.) - Removed static variables that track initialization of the sub-APIs in bli_const.c, bli_error.c, bli_init.c, bli_memsys.c, bli_thread, and bli_ind.c. We don't need to track initialization at the sub-API level, especially now that BLIS can self-initialize. - Added a critical section around the changing of the error checking level in bli_error.c. - Deprecated bli_ind_oper_has_avail() as well as all functions bli_<opname>_ind_get_avail(), where <opname> is a level-3 operation name. These functions had no use cases within BLIS and likely none outside of BLIS. - Commented out calls to bli_init() and bli_finalize() in testsuite's main() function, and likewise for standalone test drivers in 'test' directory, so that self-initialization is exercised by default.
