Jeff Squyres 54ca3310ea ompi: cleanup various string operations

Several fixes to string handling:

1. strncpy() -> opal_string_copy() (because opal_string_copy()
   guarantees to NULL-terminate, and strncpy() does not)
2. Simplify a few places, such as:
   * Since opal_string_copy() guarantees to NULL terminate, eliminate
     some memsets(), etc.
   * Use opal_asprintf() to eliminate multi-step string creation

There's more work that could be done; e.g., this commit doesn't
attempt to clean up any strcpy() usage.

This extension provides a single new function, OMPI_Affinity_str(),
that takes a format value and then provides 3 prettyprint strings as
output:

fmt_type: is an enum that tells OMPI_Affinity_str() whether to use a
resource description string or layout string format for ompi_bound and
currently_bound output strings.

ompi_bound: describes what sockets/cores Open MPI bound this process
to (or indicates that Open MPI did not bind this process).

currently_bound: describes what sockets/cores this process is
currently bound to (or indicates that it is unbound).

exists: describes what processors are available in the current host.

See OMPI_Affinity_str(3) for more details.
