Add checks to bail out if our precomputed value is less
than needed (we are already at fault).

This commit changes the behavior of bml/r2 from conditionally
registering btl progress functions to always registering progress
functions. Any progress function beloning to a btl that is not yet in
use is registered as low-priority. As soon as a proc is added that
will make use of the btl is is re-registered normally.
This works around an issue with some btls. In order to progress a
first message from an unknown peer both ugni and openib need to have
their progress functions called. If either btl is not in use after the
first call to add_procs the callback was never happening. This commit
ensures the btl progress function is called at some point but the
number of progress callbacks is reduced from normal to ensure lower
overhead when a btl is not used. The current ratio is 1 low priority
progress callback for every 8 calls to opal_progress().

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
linux: actually enable libudev based on the result of AC_CHECK_LIB
(cherry picked from open-mpi/hwloc@9549fd59af)
configure: check the actual may_alias syntax that we use
(cherry picked from open-mpi/hwloc@0ab7af5e90)
As more providers get added to libfabric, the default exclude list would need
to be updated.
Instead, we choose to include only the providers known to work by default.
New default:
- include: psm,psm2,gni
- exclude: none

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.

lines up to the next ".fi" -- which for functions that do not implement the corresponding interface
as code will have all eliminated.
Change to delete the man page's content up to the next section header ".SH"
Also in case of make V=1, we'd like to see the command line, too.
Amend OMPI_Affinity_str according to the other man-pages definitions.
There were some old/stale function names in some debugging/verbose
opal_output calls. Use __func__ instead, so that they won't become
stale in the future.
Thanks to Durga Choudhury for pointing out the issue.

Update external as well
Revise the change: we still need the MPI_Barrier in MPI_Finalize when we use a blocking fence, but do use the "lazy" wait for completion. Replace the direct logic in MPI_Init with a cleaner macro
