debugger code (not mca_topo_base_module_2_1_0_t).
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.

r29917 --> open-mpi/ompi@1a972e2c9d
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)

should be already set to the right value. This fixes a problem
identified by Guillaume Gouaillardet, where using a single
persistent receive leads to leaking the convertor stack memory.

* map-by <obj> will imply rank-by <obj> by default (leave default binding as above)
Fix a bug in the map-by <obj> mapper where we incorrectly compute the #procs to assign if the #slots > #procs

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.

more:
- Remove OPAL_ENABLE_MULTI_THREADS, since it didn't really do anything
correctly. Opal always has threads enabled at this point.
- Remove OMPI_ENABLE_PROGRESS_THREADS, since this hasn't worked in
8 years and it has performance issues we'll never be able to
overcome. Note that we have plans for re-adding async progress, using
a hybrid protocol of async and sync sends.
- OMPI_ENABLE_THREAD_MULTIPLE now determines whether the thread lock
macros do the check or not.
- Condition variables are ALWAYS polling right now, which fixes the thread
live-lock currently found when THREAD_MULTIPLE is turned on.

the value of MPI_STATUS_SIZE for the -i8 case. Thanks to Jim Parker
for bringing up the issue and providing the patch.
Separate patches are required for v1.6 and v1.7 (and will be attached
to their respective tickets), because this breaks ABI, so we need a
non-default configure option to fix the issue but knowingly break ABI.
