The prior ompi_proc_t structure had a uint8_t flag field in it, where only one bit was used to flag that a proc was "local". In that context, "local" was constrained to mean "local to this node". This commit provides a greater degree of granularity on the term "local", to include tests to see if the proc is on the same socket, PC board, node, switch, CU (computing unit), and cluster. Add #define's to designate which bits stand for which local condition. This was added to the OPAL layer to avoid conflicting with the proposed movement of the BTLs. To make it easier to use, a set of macros have been defined - e.g., OPAL_PROC_ON_LOCAL_SOCKET - that test the specific bit. These can be used in the code base to clearly indicate which sense of locality is being considered. All locations in the code base that looked at the current proc_t field have been changed to use the new macros. Also modify the orte_ess modules so that each returns a uint8_t (to match the ompi_proc_t field) that contains a complete description of the locality of this proc. Obviously, not all environments will be capable of providing such detailed info. Thus, getting a "false" from a test for "on_local_socket" may simply indicate a lack of knowledge.
