When Slurm is built against PMIx, some installations place a copy of the
PMIx library that Slurm is linking against in the Slurm PMI location.
Current configury ignores that location. The desired behavior is to look
for a PMIx lib in that location when --with-pmi is given. If the user
also specifies --with-pmix and gives a different location, then override
anything previously found and look for it where the user directed.

`short float` support of the Intel C++ Compiler (group of C and C++
compilers), at least versions 18.0 and 19.0, is half-baked. It can
compile declarations of `short float` variables and expressions of
`sizeof(short float)` but cannot compile operations of `short float`
variables. In this situation, `AC_CHECK_TYPES(short float)` defines
`HAVE_SHORT_FLOAT` as 1 and compilation errors occur in
`ompi/mca/op/base/op_base_functions.c`. To avoid this error
tentatively, we disable `short float` support when using the Intel
C++ Compiler.

The type `short float`, which is proposed in ISO/IEC JTC 1/SC 22 WG 14
(C WG), is not supported by most compilers yet. But some compilers
(including gcc 7 for AArch64 and clang 6) support `_Float16`, which
is defined in ISO/IEC TS 18661-3:2015 (ISO/IEC JTC 1/SC 22/WG 14 N1945)
as an extensions for C. If it is detected in `configure`, it is used
as an alternate type of `short float` in Open MPI internal code.
This commit adds a `configure` option `--enable-alt-short-float=TYPE`.
It can be used to specify a type other than `short float` and `_Float16`
as the alternate type.

The type `short float` is proposed for the C language in ISO/IEC JTC
1/SC 22 WG 14 (C WG) for mainly IEEE 754-2008 binary16, a.k.a.
half-precision floating point or FP16.
By this commit, `short float` and `short float _Complex` are detected
in `configure` and used in Open MPI internal code. `MPI_SHORT_FLOAT`
and its complex number version are not added yet.
This commit changes values of existing `OPAL_DATATYPE_*` macros.
This change does not affect ABI compatibility of `libmpi.so` and the
like because these values are only used in OPAL and OMPI internal code.

This code is the implementation of Software-base Performance Counters as described in the paper 'Using Software-Base Performance Counters to Expose Low-Level Open MPI Performance Information' in EuroMPI/USA '17 (http://icl.cs.utk.edu/news_pub/submissions/software-performance-counters.pdf). More practical usage information can be found here: https://github.com/davideberius/ompi/wiki/How-to-Use-Software-Based-Performance-Counters-(SPCs)-in-Open-MPI.
All software events functions are put in macros that become no-ops when SOFTWARE_EVENTS_ENABLE is not defined. The internal timer units have been changed to cycles to avoid division operations which was a large source of overhead as discussed in the paper. Added a --with-spc configure option to enable SPCs in the Open MPI build. This defines SOFTWARE_EVENTS_ENABLE. Added an MCA parameter, mpi_spc_enable, for turning on specific counters. Added an MCA parameter, mpi_spc_dump_enabled, for turning on and off dumping SPC counters in MPI_Finalize. Added an SPC test and example.

This patch disables the oshmem layer if there are no SPMLs that
will build. With the limited set of SPMLs available to support
oshmem, many builds end up installing an oshmem library that we
know will not work. There has been a bit of customer confusion
over oshmem, hopefully this will lead customers in the right
direction.

Two related changes to allow projects to not build based on
configure test results, as opposed to only reacting to
user configure options today. Use case is disabling a project
like oshmem because no communication channels can be built.
First, Move PROJECT_* AM_CONDITIONALs from the top of configure to
the bottom, so that we can change the results during configure.
Second, add a DIST_SUBDIRS to Makefile.am (and populate it in
opal_mca) so that "make dist" will work even when a project is
disabled.

The mpool/memkind component was using a deprecated "partitions" API.
This commit refactors the memkind component to make use of the
supported public API.
The public API uses 3 parameters to specify a mpool "kind":
- a memkind type (which for now is just default or HBM)
- a memkind policy
- a memkind_bits (partly to specify pagesize)
The MCA parameters were changed to reflect these memkind
parameters.
Add a make check test for sanity checking of the memkind component.

We thought there was a silent data corruption issue on POWER 7/BE
systems, so we blocked building on POWER 7/BE systems altogether. We
later figured out that it was just data hangs -- not silent data
corruption. So in hindsight, the configure block probably wasn't
necessary -- but we didn't know it at the time.
Regardless, the hangs have now been fixed, and we're removing the
POWER 7/BE block in configure.

As part of the process for addressing removal of CR/FT related
code from master (and hence from the 3.0.0 release), it was agreed
at the OMPI devel F2F on 7/13/17 that we'd break this in to two
pieces:
1) remove the configure arguments (fewer changes)
2) remove all the CR/FT code, etc. in a subsequent bigger commit
that may not make it in to 3.0.0 in time.
By doing 1), the available configure options would not change
in a subsequent 3.0.x release if we end up not being able to do 2)
before 3.0.0 is released.

This PR renames the common library for OFI libfabric from
libfabric to ofi. There are a number of reasons this
is good to do:
1) its shorter and replaces 9 characters with three for
function names for what may eventually be a fairly extensive interface
2) OFI is the term used for MTL and RML components that use
the OFI libfabric interface
3) A planned OSC component will also use the OFI term.
4) Other HPC libraries that can use OFI libfabric tend to use
the term "ofi" internally and also in their configure options
relevant to OFI libfabric (i.e. MPICH/CH4, Intel MPI, Sandia SHMEM)
There seem to be comments in places in the Open MPI source
code that indicate that this common library will be going away.
Far from it as we will want to be able to share things like
AV objects between OMPI and possibly OSHMEM components that
use the OFI libfabric interface.
This PR also adds a synonym to the --with-libfabric(-libdir)
configury options: --with-ofi and with-ofi-libdir.
