maffinity_base_bind_failure_action MCA params to the hwloc base
(hwloc_base_alloc_polocy and hwloc_base_bind_failure_action). Since
these MCA parameters were never on a release branch, I'm just
moving/renaming them outright and not leaving aliases to the old
names.
Note that some upper layer needs to call
opal_hwloc_base_set_process_membind_policy() to set the
set-by-MCA-param process-wide memory affinity policy. We can't do
this automatically during hwloc_base_open() because, for reasons
described elsewhere, opal_hwloc_topology is not automatically filled
during hwloc_base_open() (in short: potential scalability issues when
launching many MPI processes simultaneously on a single machine, for
example).
This commit was SVN r25156.
paffinity/hwloc components were still calling hwloc_topology_init/load
themselves, and not using the opal_hwloc_topology. Doh!
This commit fixes that -- these 2 components no longer have their own
copy of the topology tree; they just use opal_hwloc_topology.

the command line, hwloc is just like any other external dependency
in OMPI: if we find it, we'll use it. If we don't find it, we'll
ignore it. See comments in opal/mca/hwloc/configure.m4 for an
explanation.
* Fix some copy-n-paste errors in opal/mca/hwloc/configure.m4
w.r.t. flags coming in from the winning component.
* Add another line in ompi_info's output about whether hwloc support
is included or not.

To enable the epochs and the resilient orte code, use the configure flag:
--enable-resilient-orte
This will define both:
ORTE_ENABLE_EPOCH
ORTE_RESIL_ORTE

specify btl_tcp_if_include because btl_tcp_if_exclude is defaulted to
the loopback devices.
This commit does a few things:
* Introduce a new OPAL MCA base function:
mca_base_param_check_exclusive_string(). It checks to see that the
''user'' does not set two MCA parameters that are mutually
exclusive by checking the source of those MCS param values.
* Use the above function in many BTLs (and the OOB TCP) to ensure
that <foo>_if_include and <foo>_if_exclude are not both specified
''by the user''.
* Re-arrange many of these BTLs to move their MCA registration code
into a separate component_register() function (vs. the
component_open() function).
This code has been nominally reviewed and checked by Ralph, George,
Terry, and Shiqing.

It was agreed that opal_init_util had wound up being used in unintended ways, which raised the problem of getting reference counts to work right. However, fixing it would involve more pain than it was worth - and so long as the other layers are made to behave similarly, I have no preference either way.
Complete implementation will follow - for now, this just reverts the prior changes.
