Some older versions of libibverbs do not have `ibv_event_type_str`,
leading to compilation failures on older machines, irrespective of
whether they could ever support usNIC anyway. If we encounter any other
build issues related to "old verbs" then we should just cause the usnic
BTL to disqualify itself when it encounters "old" traits.
Thanks to Paul Hargrove for reporting the issue:

The error was caused by leaving the pipe to the async thread uninitialized, then writing to it regardless of this.
Fix is to check the existance of the async thread and the pipe to it.

The initialization code did several allgathers on void *'s using
MPI_LONG_LONG_INT. This will produce the wrong result on 32-bit
platforms. Instead use MPI_BYTE with count = sizeof (void *).

Found two bugs in basesmuma:
- Release all resources when tearing down the bcol module.
- Allways call the allreduce in the smcm code. We do not know
beforehand whether all procs have all the files mapped.

The problem was caused by the static request optimization. The buffered send case
is much like the isend case in that the request structure may be needed after
MPI_Bsend completes. Fix this case by calling isend and freeing the resulting
request.

This change does not appear to increase the small message latency of ping-pong
benchmarks and fixes an issue found by our ibm datatype tests.

opal does not always define MB. It is recommended that opal_atomic_[rw]mb is
called instead. We will need to address the cases where these functions are
no-ops on weak-memory ordered cpus.

Several changes are contained in this commit:
- Clean up tabs and trailing whitespaces
- Use consistent indentation in changed files
- Remove unused code. None of the removed code will ever have been
used in a trunk build.
- Clean up the smcm code quite a bit
- Do not fflush stderr and use opal_output instead of fprintf.
These changes have been tested on Cray XE-6 and PSM systems.

During the commits to make the C/R code compile again the
blocking receive calls were replaced by non-blocking
which broke the code. This patch uses ORTE_WAIT_FOR_COMPLETION()
to wait until the non-blocking calls have finished.

This commit fixes one warning that should have caused coll/ml to segfault
on reduce. The fix should be correct but we will continue to investigate.

for 32-bit architectures.
This commit also modifies _OMPI_CHECK_HEADER to use AC_CHECK_HEADERS instead
of AC_CHECK_HEADER. This allows components to check for multiple headers
instead of just one. The new semantics of the header check in OMPI_CHECK_PACKAGE
are to return success if at least one of the specified headers exists. The new
semantics will not break current usage.
