NOTE: Building with external pmix *requires* that you also build with external libevent and hwloc libraries. Detect this at configure and error out with large message if this requirement is violated.
Closes#1204 (replaces it)
Fixes#1064
Rename the pmix1xx component to pmix111 so it reflects the actual release it includes
Resolve the problem of PMIx being passed a bogus --with-platform argument when configuring the PMIx tarball code. There is no reason we should be passing --with-platform arguments to any internal subdirectory, so just leave that out when constructing the opal_subdir_args variable.
Update the PMIx code and continue attempting to debug direct modex
Fix a problem in the ORTE PMIx server - there was an early intent to optimize the direct modex by fetching data for all procs from the target job on the remote node, instead of fetching the data one proc at a time. However, this was never completely implemented, and so we would hang if we had multiple overlapping requests for data from more than one proc on the node.
Update PMIx to v1.1.2
Mofed 2.2 does not have the IBV_EXP_QP_INIT_ATTR_ATOMICS_ARG attribute
flag. Add a check to fix compilation for mofed 2.2. This commit only
fixes complilation with the older mofed. It will not allow an Open MPI
compiled with mofed 2.3 or newer to work on a machine with mofed 2.2.

This update adds an additional check (if supported) to see if 8-byte
atomics are supported by the hardware. If 8-byte atomics are not
supported the atomics support is disabled.
This commit also includes some cleanup.

This commit adds support for fetch-and-add and compare-and-swap when
using the mlx5 driver. The support is only enabled if the expanded
verbs interface is detected. This is required because mlx5 HCAs return
the atomic result in network byte order. This support may need to be
tweaked if Mellanox commits their changes into upstream verbs.

./configure --with-platform=contrib/platform/$name will apply all patches
found in contrib/platform/$name.patches/ directory during "configure" phase.
It allows vendors to distribute not-accepted or vendor-specific patches as
part of standard ompi tarball and reduce burden of keeping private repos.
Added:
* VPATH support
* $srcdir/.platform_patches file created if patches already applied
* configure will fail with error if patch cannot be applied (using dry-run)
* configure will fail if patches modifying *.[am,m4] files (unsupported)
* remove unused patch_errors var
* set with_ident_string if platform file applied patches

The Intel 2016 compiler suite apparently only partially supports the
!GCC pragmas (prior versions either didn't support it at all, or our
existing configure test was sufficient to disqualify !GCC pragma
support when compiling with the Intel compiler).
With the existing configure test, the Intel 2016 compiler suite would
*pass* the test and therefore think that it could use !GCC as the
"ignore TKR" pragma. However, the "!GCC ATTRIBUTES NO_ARG_CHECK"
pragma doesn't work with scalar integers (although it seems to work
for the other types in this test).
This commit adds a scalar integer test to the ignore TKR pragma
configure test, which is enough to make the Intel 2016 compiler suite
fail with !GCC (this then allows configure to advance on to trying the
!DEC pragma, which *does* work properly with the Intel 2016 compiler
suite).
Thanks to Fabrice Roy for reporting the problem.

As of v15.7, the PGI Fortran compiler does not properly support how
Open MPI uses the "USE ... ONLY" Fortran syntax to include modules
with conflicting symbol definitions (interestingly, pgfortran only has
a problem with this when compiling with -g).
In short, OMPI uses "USE :: module_aaa, ONLY: foo" and "USE ::
module_bbb, ONLY: bar" to use modules aaa and bbb, even though they
contain conflicting definitions for some symbols. However, the use of
the ONLY clause should preclude the inclusion of the conflicting
symbols -- as the word implies, it should direct the compiler to
*only* use the symbols identified by the clause (i.e., foo and bar, in
this example).
This commit adds a configure test for this capability. If the
compiler fails to build a simple test that mimics this behavior, then
disable the mpi_f08 bindings.
Fixesopen-mpi/ompi#857
Only set OMPI_FORTRAN_BUILD_SIZEOF to 1 if $ompi_fortran_happy is also
1 (i.e., we're building the Fortran interface). This prevents
building [p]size_f.f90 and trying to compile it if there is no Fortran
compiler, for example.
This commit removes alpha asm support. No current processor
manufacturer makes chips compatible with DEC alpha and no
participating organization has alpha processors. This makes it
difficult to support alpha via assembly.
This doesn't mean Open MPI will no longer build/work on alpha
processors. It should continue to work with gcc's builtin sync
atomics.

Fortran uses objects (ompi_f08_mpi_comm_world, mpi_fortran_bottom,, ...) that are defined in C.
Some compilers have different requirements on how these objects should be aligned.
Smaller alignment in C can lead to several confusing warnings from the linker, so try to
find the alignment expected by Fortran compiler, and inform the C compiler.
