Details: - Completely re-wrote the contiguous memory allocator (bl2_mem.c). The new allocator instantiates and initializes three separate memory pool objects, each one associated with a separate array of contiguous memory blocks, each block of fixed and uniform size. (The three pools are for allocating mc-by-kc blocks of A, kc-by-nc panels of B, and mc-by-nc panels of C.) The pool objects use a stack structure internally to track which blocks in the region have been "checked out" to a thread and which are still available. Critical regions are now clearly marked and adaptable to parallel environments (e.g. OpenMP). Memory pools are set up when bl2_init() is called. - Added a new field to the packm control tree node, which indicates what kind of packed buffer is being allocated. The enumerated type for this argument is defined as packbuf_t in bl2_type_defs.h. - Updated level-3 _cntl.c files to pass in the appropriate value for a new packbuf_t argument to bl2_packm_cntl_obj_create(). - Moved some macros called by packm_init_pack() from bl2_obj_macro_defs.h to bl2_mem_macro_defs.h. - Added BLIS_MAX_NUM_THREADS to bl2_config.h, which we use as the default number of blocks of A reserved for the memory allocator. - Deprecated bl2_align_dim(). Replaced usage with that of bl2_align_dim_to_mult(). Turns out that typically we don't need to align a dimension to the system alignment, since that value has to do with starting addresses, whereas the values we are dealing with are unitless dimensions.
