This commit adds a new btl for one-sided and two-sided. This btl
uses the uct layer in OpenUCX. This btl makes use of multiple uct
contexts and per-thread device pinning to provide good performance
when using threads and osc/rdma. This btl has been tested extensively
with osc/rdma and passes all MTT tests on aries and IB hardware.
For now this new component disables itself but can be enabled by
setting the btl_ucx_transports MCA variable with a comma-delimited
list of supported memory domains/transport layers. For example:
--mca btl_uct_memory_domains ib/mlx5_0. The specific transports used
can be selected using --mca btl_uct_transports. The default is to use
any available transport.

The giant size of the TCP proc struct is causing a problem in some
environments (because it is allocated on the stack), and it was too
big, anyway.
Instead, use a hash map. That way, it starts small and can grow if it
needs to. It also makes no assumptions about the values of the kernel
interface indexes.
Fixes#5292.

Since the new binding option is tied to the --cpu-list orterun CLI
option, make the --bind-to option reflect the same name (vs. the
--cpu-set CLI option, which is entirely different). For example:
mpirun --bind-to cpu-list:ordered ...
Note that "--bind-to cpulist:ordered" is accepted as a synonym,
because people will be lazy.
Also add some minor updates to the orterun.1in man page for
clarification.

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.

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.
