Eugene Loh 3d44f97572 Fix hwloc get-cpubind routine for Solaris. FIRST, check

processor_bind to see if we're bound to a single core.
If not, THEN check lgroup affinity.  Already CMR'ed to
v1.6 (trac 3507) and fixed upstream in hwloc (r5295).

base

Fix rank_file operations. We changed the syntax to use semi-colons between multiple slot assignments so that we could use the comma to separate specific cores, but somehow the flex definitions didn't get updated to accept that character. We also incorrectly zero'd the bitmap between slot assignment sections, and so multiple slot assignments only wound up making the last one in the list.

hwloc.h

Get the trunk to build again when --without-hwloc is specified. Move a couple of key type definitions and utilities out from under the HAVE_HWLOC test so they are always available as they don't really depend on hwloc's presence. Tell two compnents not to build if hwloc is disabled:

Makefile.am

Per the RFC from Jeff, move hwloc from opal/mca/common to its own static framework ala libevent. Have ORTE daemons collect the topology info at startup and, if --enable-hwloc-xml is set, send that info back to the HNP for later use. The HNP only retains unique topology "templates" to reduce memory footprint. Have the daemon include the local topology info in the nidmap buffer sent to each app so the apps don't all hammer the local system to discover it for themselves.

Notes for hwloc component maintainers:

1. There can only be *1* hwloc version component at a time.
   Specifically: if there are multiple hwlocXYZ components (i.e.,
   different versions of hwloc), then they must all be .ompi_ignore'd
   except for 1.  This is because we currently m4_include all of the
   underlying hwloc's .m4 files -- if there are multiple hwlocXYZ
   components, I don't know if m4 will barf at the multiple,
   conflicting AC_DEFUNs, or whether it'll just do something
   completely undefined.

1a. As a consequence, if you're adding a new hwloc version component,
   you'll need to .ompi_ignore all others while you're testing the new
   one. 

2. If someone wants to fix #1 someday, we might be able to do what we
   do for libevent: OMPI_CONFIG_SUBDIR (instead of slurping in hwloc's
   .m4 files).
