This commit fixes a segmentation fault that occurs if a device can be
initialized but not used. In this case the devices_count is not equal
to the number of usable devices in the devices pointer array.
Thanks to @artpol84 for tracking this down.

The way the gni btl is currently coded,
it will run completely out of gas on KNL at
123 processes/node. Since there are bound to be
those who try to run a MPI process/hyperthread
on KNL nodes, the fma sharing mode needs to be requested.

The rdma_disconnect function specifies that both the server and client
should call rdma_disconnect. The code was not calling rdma_disconnect
on an endpoint if the event came before the endpoint finalization.

Before dynamic add_procs the openib_btl_size_queues was called exactly
once for non-dynamic jobs. Now the function is called on each new
connection so the calculation was wrong. Re-wrote the function to
correctly calculate the CQ size and only attempt to adjust the CQ if
the requested size has changed. This fixes a bug when using the openib
btl on psm2 hardware that is caused by the time needed to resize a
CQ. The overhead was causing udcm to timeout and fail.

This fixes https://github.com/open-mpi/ompi/issues/1732: i.e., the
case where the outer project has its own check for
<valgrind/valgrind.h>, but also supplements CPPFLAGS (to find
Valgrind's header files) before doing that check.

Ideally, we would tell OMPI to disable autoconf's caching of our
valgrind check result so that its check gets the right result after
adding CPPFLAGS. Not sure if we can do that.
For now, just disable our Valgrind code in embedded mode.
This will keep the x86 backend enabled under Valgrind but
it will auto-disable itself when finding identical APIC ids anyway
(because CPUID returns same outputs for all PUs).

This commit fixes a programming error when using an aries nic. The
documentation of ugni shows that only the local alignment restriction
for get was lifted on aries. There is still a remote address alignment
restriction.
