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)
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.

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
WRAPPER_EXTRA flags are checked *before* the POST_CONFIG macro is
invoked. So set them in the main CONFIG macro.

xlc 13.1.0 crashes because of our may_alias attributes in nolibxml.c
on Power7. libxml.c and nolibxml.c are the only may_alias users for now,
so change our configure check to match the actual code using it.
Thanks to Paul Hargrove for reporting and debugging the issue,
and providing the patch.

This commit disables the linux patcher component due to a limitation
in loader patching. While this component is effective in patching
calls made within Open MPI and by the application it fails to hook
calls made within glibc. This means the munmap call made by free is
not correctly hooked. Until this problem can be resolved this
component will remain disabled. If it can't be resolved this component
should probably be removed.

The table of contents (TOC) code only appears to only apply to
ppc64. The code was incorrectly assuming the existence of the TOC on
ppc32. This commit updates the necessary code to only apply to ppc64.

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.

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.
