Reset topology usage for each node as we bind as multiple nodes may be linked to the same topology object. This will need to be revisited for scale as it does take some non-zero time to reset the usage each iteration. However, storing individual topology objects for every node consumes memory, so it's a tradeoff.

Also fix another compiler warning (using %p to print a (void*)).

This commit was SVN r29966.
usnic_channel_finalize() was deregistering recv buffers before
destroying the QP to which they were posted. The QP needs to be
destroyed first so that the NIC does not attemp tto write to
deregistered memory, causing the DMAR messages.

I checked: we do a similar thing for coll in the communicator struct
(i.e., leave the version number off the module struct). I confess to
not remembering ''why'' we leave the version number off, but it seems
to be consistent this way...

* automatically retrieve the hostname (and all RTE info) for all procs during MPI_Init if nprocs < cutoff
* if nprocs > cutoff, retrieve the hostname (and all RTE info) for a proc upon the first call to modex_recv for that proc. This would provide the hostname for debugging purposes as we only report errors on messages, and so we must have called modex_recv to get the endpoint info
* BTLs are not to call modex_recv until they need the endpoint info for first message - i.e., not during add_procs so we don't call it for every process in the job, but only those with whom we communicate
My understanding is that only some BTLs have been modified to meet that third requirement, but those include the Cray ones where jobs are big enough that launch times were becoming an issue. Other BTLs would hopefully be modified as time went on and interest in using them at scale arose. Meantime, those BTLs would call modex_recv on every proc, and we would therefore be no worse than the prior behavior.
This commit revises the MPI-RTE interface to pass the ompi_proc_t instead of the ompi_process_name_t for the proc so that the hostname can be easily inserted. I have advised the ORNL folks of the change.

includes various fixes all over the C/R code which are
hard to group like the other patches.
Changes from V1:
* explain why mca_base_component_distill_checkpoint_ready no longer works
* compare return result of opal functions with OPAL_* values
Changes from V2:
* use orte_rml_oob_ft_event() instead of referencing through the modules
* properly protect variable (thanks to --enable-picky)

identified by Guillaume Gouaillardet, where using a single

got linked together (work on one caused work in the other):
* Clean up a bunch of VAR_SCOPE issues in configure. This includes:
* Using VAR_SCOPE_PUSH and VAR_SCOPE_POP in more places
* Cleaning up the use of some shell variables (e.g., name them better)
* Add support for external libevent via
--with-libevent=<dir-to-libevent-install-tree>, as specifically
asked for by downstream packagers.
* Revamp how wrapper compiler RPATH (and RUNPATH) support is done.
The external libevent work exposed weakenesses in how the original
RPATH/RUNPATH work was done, so we had to re-do it to be a bit more
robust.
This work has not yet been tested on Solaris.
