Details: - Added support for an experimental gemm macro-kernel incrementally packs one micro-panel of B at a time. This is useful for certain special cases of gemm where m is small. - Minor changes to default values of clarksville configuration. - Defined BLIS_PACKED_BLOCKS as part of pack_t type, even though we do not yet have any use (or implementation support) for block storage. - Comment update to bli_packm_init.c.
