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.

This commit adds support for Cray Aries atomic operations. This
includes 32-bit and floating point support.
Signed-off-by: Nathan Hjelm <hjelmn@lanl.gov>
This commit add support for more atomic operations and type. The
operations added are logical and, logical or, logical xor, swap, min,
and max. New types are 32-bit int by using the
MCA_BTL_ATOMIC_FLAG_32BIT flag, 64-bit float by using the
MCA_BTL_ATOMIC_FLAG_FLOAT flag, and 32-bit float by using both
flags. Floating point numbers are supported by packing the number in
as an int64_t or int32_t. We will update the btl interface in the
future to make this less confusing.

Before dynamic add_procs support was committed to master we called
add_procs with every proc in the job. The XRC code in the openib btl
was taking advantage of this and setting the number of work queue
entries (WQE) based on all the procs on a remote node. Since that is
no longer the case we can not simply increment the sd_wqe field on the
queue pair. To fix the issue a new field has been added to the xrc
queue pair structure to keep track of how many wqes there are total on
the queue pair. If a new endpoint is added that increases the number
of wqes and the xrc queue pair is already connected the code will
attempt to modify the number of wqes on the queue pair. A failure is
ignored because all that will happen is the number of active send work
requests on an XRC queue pair will be more limited.

For non x86_64 platforms we can use XPMEM_MAXADDR_SIZE.

This commit reduces the overhead of calling the ugni progress
function. It does the following:
- Check for new connections once every eight calls.
- Do not call remote smsg progress unless we are connected to at
least one remote peer.
- Do not call rdma progress unless at least one rdma fragment is
outstanding.
- Check endpoint wait list size before obtaining a lock.

Our checks and the ones of libevent are somewhat flawed.
If adding multiple "-framework" to CXXFLAGS or CFLAGS, we strip
the keyword from the command-line, not good.
libevent however assumes plain gcc without testing properly
that the compiler supports -Wno-deprecated-declarations.
The OPAL_CMA_NEED_SYSCALL_DEFS is always defined/set to 0 or 1. Therefore
instead of checking if the macro is defined, we have to look at the value
itself.

Take another shot at untangling the spaghetti
orterun: fix for command line parsing
orte-submit calls opal_init_util () before parsing out MCA command line
options (-mca, -am, etc). This prevents mpirun from setting opal MCA
variables for some frameworks as well as the MCA base. This is because
when a framework is opened all of its variables are set to read-only.
Eventually we want to lift this restriction on some MCA variables but
since -mca is affected we must parse out the MCA command line options
before opal_init_util(). This commit fixes the bug by adding a new
option to opal_cmd_line_parse (ignore unknown option) so orte-submit
can pre-parse the command line for MCA options.

Minor cleanups to avoid releasing/recreating the cmd line
Remove contrib/windows/
Merge hwlocXYZ/hwloc/README-ompi.txt back into hwlocXYZ/README-ompi.txt instead of having both.
Add README.txt in new automake-required directory contrib/systemd/
Keep the following patches applied since they are not in 1.11.3

This commit fixes several bugs in the registration cache code:
- Fix a programming error in the grdma invalidation function that can
cause an infinite loop if more than 100 registrations are
associated with a munmapped region. This happens because the
mca_rcache_base_vma_find_all function returns the same 100
registrations on each call. This has been fixed by adding an
iterate function to the vma tree interface.
- Always obtain the vma lock when needed. This is required because
there may be other threads in the system even if
opal_using_threads() is false. Additionally, since it is safe to do
so (the vma lock is recursive) the vma interface has been made
thread safe.
- Avoid calling free() while holding a lock. This avoids race
conditions with locks held outside the Open MPI code.
Fixesopen-mpi/ompi#1654.
