Details: - Added a new configure option, --[en|dis]able-packbuf-pools, which will enable or disable the use of internal memory pools for managing buffers used for packing. When disabled, the function specified by the cpp macro BLIS_MALLOC_POOL is called whenever a packing buffer is needed (and BLIS_FREE_POOL is called when the buffer is ready to be released, usually at the end of a loop). When enabled, which was the status quo prior to this commit, a memory pool data structure is created and managed to provide threads with packing buffers. The memory pool minimizes calls to bli_malloc_pool() (i.e., the wrapper that calls BLIS_MALLOC_POOL), but does so through a somewhat more complex mechanism that may incur additional overhead in some (but not all) situations. The new option defaults to --enable-packbuf-pools. - Removed the reinitialization of the memory pools from the level-3 front-ends and replaced it with automatic reinitialization within the pool API's implementation. This required an extra argument to bli_pool_checkout_block() in the form of a requested size, but hides the complexity entirely from BLIS. And since bli_pool_checkout_block() is only ever called within a critical section, this change fixes a potential race condition in which threads using contexts with different cache blocksizes--most likely a heterogeneous environment--can check out pool blocks that are too small for the submatrices it wishes to pack. Thanks to Nisanth Padinharepatt for reporting this potential issue. - Removed several functions in light of the relocation of pool reinit, including bli_membrk_reinit_pools(), bli_memsys_reinit(), bli_pool_reinit_if(), and bli_check_requested_block_size_for_pool(). - Updated the testsuite to print whether the memory pools are enabled or disabled.
