This now results in the procs being bound within their assigned location. It also causes us to use only the 0th HT on a core unless --use-hwthread-cpus has been specified (in which case, we use all the HTs in a core). Bind to core binds you to all HTs regardless - the --use-hwthread-cpus only impacts the oversubscribed determination and when binding to HT.

* Moved "check basics" sanity check from openib BTL to common/verbs
(which also allows us to have openib ''not'' include
<infiniband/driver.h>, which is a Very Good Thing)
* Add new ompi_common_verbs_qp_test() function, which tests to see
whether a device supports RC and/or UD QPs. The openib BTL now
uses this function to ensure that the device supports RC QPs.
* Rename ompi_common_verbs_find_ibv_ports() to be
ompi_common_verbs_find_ports() -- the "ibv" was redundant.
* Re-work ompi_common_verbs_find_ports() to use
ompi_common_verbs_qp_test() instead of testing for RC/UD QPs itself
* Add bunches of opal_output_verbose() to the find_ports() routine
(to help diagnosing connectivity problems -- imaging running with
--mca btl_base_verbose 10; you'll see all the find_ports() test
results)
* Make ompi_common_verbs_qp_test() warn if devices/ports are supplied
in the if_include/if_exclude strings that do not exists (quite
similar to what the openib BTL does today).
* Add ompi_common_verbs_mca_register() function, which registers
common verbs MCA params. It will also register MCA param synonyms
for thse MCA params to upper-level components (e.g.,
btl_<upper-level-component>_<the-mca-param>).
* common_verbs_warn_nonexistent_if: warn if
if_include/if_exclude-specified devices or ports do not exist.

As a secondary cleanup, the HNP doesn't need to update its nidmap during an xcast as it already has an up-to-date picture of the situation. So just dump that data and move along.

Ticket 3309 --> https://svn.open-mpi.org/trac/ompi/ticket/3309
We ran into a case where the OMPI SVN trunk grew a new acceptable MCA
parameter value, but this new value was not accepted on the v1.6
branch (hwloc_base_mem_bind_failure_action -- on the trunk it accepts
the value "silent", but on the older v1.6 branch, it doesn't). If you
set "hwloc_base_mem_bind_failure_action=silent" in the default MCA
params file and then accidentally ran with the v1.6 branch, every OMPI
executable (including ompi_info) just failed because hwloc_base_open()
would say "hey, 'silent' is not a valid value for
hwloc_base_mem_bind_failure_action!". Kaboom.
The only problem is that it didn't give you any indication of where
this value was being set. Quite maddening, from a user perspective.
So we changed the ompi_info handles this case. If any framework open
function return OMPI_ERR_BAD_PARAM (either because its base MCA params
got a bad value or because one of its component register/open
functions return OMPI_ERR_BAD_PARAM), ompi_info will stop, print out
a warning that it received and error, and then dump out the parameters
that it has received so far in the framework that had a problem.
At a minimum, this will show the user the MCA param that had an error
(it's usually the last one), and ''where it was set from'' (so that
they can go fix it).
We updated ompi_info to check for O???_ERR_BAD_PARAM from each from
the framework opens. Also updated the doxygen docs in mca.h for this
O???_BAD_PARAM behavior. And we noticed that mca.h had MCA_SUCCESS
and MCA_ERR_??? codes. Why? I think we used them in exactly one
place in the code base (mca_base_components_open.c). So we deleted
those and just used the normal OPAL_* codes instead.
While we were doing this, we also cleaned up a little memory
management during ompi_info/orte-info/opal-info finalization.
Valgrind still reports a truckload of memory still in use at ompi_info
termination, but they mostly look to be components not freeing
memory/resources properly (and outside the scope of this fix).
