This commit fixes a compile/link issue caused by vader. The vader btl
was using OPAL_THREAD_ADD64 to increment a counter which may not be
available on 32-bit systems. Changed to use OPAL_THREAD_ADD_SIZE_T
which will be 64-bit or 32-bit depending on the system.

ebx can not be clobbered when using -fPIC so save and restore the
register instead of allowing it to be clobbered.

instead of doing AC_CHECK_HEADERS+AC_CHECK_LIB and only using the result of the former.
Thanks to Paul Hargrove for reporting the issue (OMPI build with -m32).

This commit fixes a compilation issue with some versions of exp
verbs. In some cases struct ibv_exp_device_attr does not have either
the exp_atom or exp_atomic_cap fields. It is fine to drop one check
and fall back to the non-exp attribute check on the other.

Add a feature check for clflush before trying to use the clflush
instruction. As far as I can tell there is no equivalent before the
SSE2 instruction set.

The function signature of mremap on BSD (NetBSD, FreeBSD) differs from
the linux version. Added support for the BSD style of mremap.

This commit fixes a compile error when the system has mremap but not
MREMAP_FIXED. In this case we do not care about the value of
new_address as the argument does not exist.

In some rare cases when a process receives the connect ack while
locally updating the peer endpoint structure, we could drop the
incomming connect ack due to the fact that the send handler is
protected with a try lock (on the endpoint) and our initial send
event was not persistent. Making the send event persistent solves
all issues.
Rather than have a stub function for the pmix fence_nb
operation, just set to NULL. Causes fewer problems.

This commit fixes a race between a thread calling the tcp btl's
add_procs and a thread processing an incomming connection. The race
occured because the add_procs thread adds a newly created proc object
to the hash table *before* the object is fully initialized. The
connection thread then attempts to use the object before the endpoints
array on the object has beeen allocation. The fix is to only add the
proc to the hash table after it has been completely initialized.

This commit fixes an error in the failure path of leave_pinned. When
the rcache tries to enable leave_pinned but leave_pinned was not
specifically requested (opal_leave_pinned == -1) the code was
erroneously printing an error and returning NULL.

The opal_mem_hooks_release_hook does not have const on the pointer
(though it probably should). This commit eliminates a warning by
casting away the const until opal_mem_hooks_release_hook is updated to
use const.

This is complicated stuff: add some comments so that future
maintainers have some rationale to understand the way things have been
done.

Define OPAL_MAXHOSTNAMELEN to be either:
(MAXHOSTNAMELEN + 1) or
(limits.h:HOST_NAME_MAX + 1) or
(255 + 1)
For pmix code, define above using PMIX_MAXHOSTNAMELEN.
Fixup opal layer to use the new max.

The math for checking the number of QPs and CQs per usNIC/VF was
incorrect, allowing you to run MPI processes even when usNICs (i.e.,
VIC VFs) had fewer QPs and CQs than were necessary. This led to a
confusing error later when fi_enable(3) failed (because we lazily
create QPs). Fixing the math here ensure that we actually print a
helpful error message telling the user specifically what is wrong.

The heterogeneous code need to gracefully handly the contiguous
datatype loops in order to have the "#if 0" code path enabled again.
This is a performance issue (the correctness is guaranteed by the
current code).
These macros should really be named OPAL_SUMMARY_*; they're used in
all projects, and therefore should be in the lowest later project (OPAL).
