Use of the old ompi_free_list_t and ompi_free_list_item_t is deprecated. These classes will be removed in a future commit. This commit updates the entire code base to use opal_free_list_t and opal_free_list_item_t. Notes: OMPI_FREE_LIST_*_MT -> opal_free_list_* (uses opal_using_threads ()) Signed-off-by: Nathan Hjelm <hjelmn@lanl.gov>
