Cover all data types for OPAL-to-PMIx conversion, generating error logs when we hit something we don't support

In the opal list parsing behavior paths should be separated by ':' while files are separated by ','. In the opal and pmix code (the pmix fix is in a separate commit) there was a mistake in the parsing such that files were being separated by ':' when they should be separated by ','s. This commit attempts to address this mismatch.

This commit add support for scalable endpoint to enhance multithreaded
application performance. The BTL will detect the support from ofi
provider and will fallback to normal usage of scalable endpoint is not
supported.
NEW MCA parameters:
- mca_btl_ofi_disable_sep: force the btl to not use scalable endpoint.
- mca_btl_ofi_num_contexts_per_module: number of communication context
to create (should be the same as number of thread).

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.

FI_MR_UNSPEC is not supposed to be used beyond ofi version 1.5. This
commit replaces FI_MR_UNSPEC with the new FI_MR_BASIC mode bits
(FI_MR_PROV_KEY | FI_MR_ALLOCATED | FI_MR_VIRT_ADDR).
The btl functionality remains the same.

OFI sockets provider will sometime return FI_EINTR. Apparently this flag
does not exist in OFI version 1.5. This commit added an ifdef check.

This commit adds patcher support of aarch64. The current
implementation uses mov, movk, and br to perform the jump. This uses 5
instructions.

This commit fixes problem where users have libfabric version < 1.5
installed and build failed because the new MR modebits does not exist.

Get the OMPI rte/pmix component working. This was tested using PRRTE as the RM, configuring OMPI using:
* autogen --no-orte
* with external libevent, external hwloc, and external PMIx master
* configuring PMIx master with the same libevent and hwloc
* execute the application using PRRTE's "prun" launcher, which has the same cmd line as ORTE's mpirun
Note that PMIx master appears to have a bug in the event notification system that caches job termination events. Thus, the first execution runs fine, but subsequent executions cause an "abort" when the OMPI default error handler is invoked upon notification of the prior job's termination. Will work that separately.

(cherry picked from commit 134cca9ac0de092d767999357573a31703f72292)
This commit added new transport layer to be used with osc rdma module.
This BTL provides put, get, atomic and fetch atomic operations. It can
be used with multiple hardware vendors as long as they have their
provider under Libfabric and have the right capabilities.

Don't do a recursive search (hence no need for *idx anymore).
Find the level depth, to hide cache-issues first.
Then iterate over that level to find the objects we want.

df_search_min_bound() would need to be fixed for hwloc 2.0,
but it's only used in opal_hwloc_base_find_min_bound_target_under_obj()
which isn't used anymore. So just remove all of them.
