This patch changes all send/send_buffer occurrences in the C/R code
to send_nb/send_buffer_nb.
The new code compiles but does not work.
Changes from V1:
* #ifdef out the code (so it is preserved for later re-design)
* marked the broken C/R code with ENABLE_FT_FIXED
Changes from V2:
* just replace the blocking calls with the non-blocking calls
* all #ifdef's introduced in V1 are gone
* send_* returns error code or ORTE_SUCCESS (not the number of bytes)
This commit was SVN r30036.
This patch changes all recv/recv_buffer occurrences in the C/R code
to recv_nb/recv_buffer_nb.
The old code is still there but disabled using ifdefs (ENABLE_FT_FIXED).
The new code compiles but does not work.
Changes from V1:
* #ifdef out the code (so it is preserved for later re-design)
* marked the broken C/R code with ENABLE_FT_FIXED
Changes from V2:
* only #ifdef out the code where the behaviour is changed
(used to be blocking; now non-blocking)

Fix comm_spawn on a single host - with the new default mapping scheme, we were incorrectly computing the number of procs to put on the node.

Some NFS scenarios can result in an infinite ESTALE return, which will
hang ROMIO. This commit causes ROMIO to error out after a large number
of retries instead of spinning forever.

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.

hard to group like the other patches.

* explain why mca_base_component_distill_checkpoint_ready no longer works

Changes from V2:
* use orte_rml_oob_ft_event() instead of referencing through the modules

Note that this event should never happen within a single OMPI job,
because OMPI will ignore usnic ports that are down. The PORT_ACTIVE
event should only occur if a port ''was'' down and is now ''up''. But
what the heck -- if we ever do get this event, it is harmless -- just
ignore it.

This is helpful in the work for #3694: ensure that many places that
eventually end up in configure don't overly-pollute the global shell
variable space (because debugging accidental shell variable pollution
can be a real pain).
