Bump up max send size. Gives much better performance for GPU transfers while only decreasing host transfers by a small amount.

hwloc: only add CPPFLAGS if hwloc is actually being built

As pointed out by @ggouaillardet, we were adding some unnecessary -I

slightly updates the hwloc191 component configury to only add such
things when the component is, in fact, going to be
compiled/installed.

Change the way we register the sm memory pool with CUDA. Rather than just registering local free lists, register the entire pool as the local process does not know which memory the remote processes are using for free lists. Fixes performance problem we were seeing with copying out of memory (since host piece was not pinned).

Fix the race condition in endpoint connection initialization. The race
...
was quite subtle, and only happened on the process with the smallest
guid (as this process will tear down the connection created locally and
replace it with the result of accept). If multiple threads are active in
the system, the deadlock occurs during the recv event deletion as one
thread will hold the recv event lock of the endpoint and try to access
the TCP event base lock, while the other thread will hold the TCP event
base lock while trying to access the recv event lock (in case data is
available on the socket).
The proposed solution let the event callback fail to process the data,
preventing the deadlock and allowing the other thread to always complete
it's job. As the event is not execute the same triggered will trigger
again at the next opportunity, so this solution introduce a minimal
delay in the connection establishement.

It looks like the guess_len function in our local printf.c has some questionable code in it. Now that we are checking in configure for vsnprintf, take advantage of that check to use the far simpler method if it is available. Given that we no longer support such ancient systems where this might not be available, one suspects the other questionable code may no longer be required - but set that aside for another day.

opal_lifo: fix potential race condition when using 128-bit atomics
...
On x86_64 reading a 128-bit value requires multiple instructions.
Under some conditions if the counted pointer counter is read before
the item pointer the fifo can be left in an inconsistent state. This
commit forces the read of the counter to always be read first.
The fifo does not appear to suffer from the same race.
