Revamp the event notification integration to rely on the PMIx event chaining and remove the duplicate chaining in OPAL. This ensures we get system-level events that target non-default handlers.
Restore the hostname entries for MPI-level error messages, but provide an MCA param (orte_hostname_cutoff) to remove them for large clusters where the memory footprint is problematic. Set the default at 1000 nodes in the job (not the allocation).

Plug a minor memory leak. Tell the PMIx server not to create a dstore memory region for the daemon job as there is nobody to share it with.

There are only five places in the non-daemon code paths where opal_hwloc_topology is currently referenced:
* shared memory BTLs (sm, smcuda). I have added a code path to those components that uses the location string
instead of the topology itself, if available, thus avoiding instantiating the topology
* openib BTL. This uses the distance matrix. At present, I haven't developed a method
for replacing that reference. Thus, this component will instantiate the topology
* usnic BTL. Uses the distance matrix.
* treematch TOPO component. Does some complex tree-based algorithm, so it will instantiate
the topology
* ess base functions. If a process is direct launched and not bound at launch, this
code attempts to bind it. Thus, procs in this scenario will instantiate the
topology
Note that instantiating the topology on complex chips such as KNL can consume
megabytes of memory.

Looks like we missed one place where we needed to swap OMPI_UNIQUE for
OMPI_FLAGS_UNIQUE. Thanks to Phil Tooley (@Telemin) for reporting the
issue.
Fixes#2635.

MPI_T_pvar_get_index was returning an incorrect index. The index
was never set correctly while registering the performance variables.
Additionally fix a missing case in the mca_base_var_type_t to MPI
datatype conversion. This type is currently used for control variables
registered by mxm, fca and hcoll components.

- Fix capitolization typos
- Make comment more correct / flow better
- Use AM_CPPFLAGS, not DEFAULT_INCLUDES
- Remove extra "hwloc/" from external hwloc.h specification

This is news to me: I didn't know that some distros do not set $HOME.
So use "~" instead, and only try to grep ~/.rpmmacros if it exists.

--with-libltdl is now added (via AC_ARG_WITH) in
opal/mca/dl/libltdl/configure.m4 -- it no longer belongs up here in
this top-level m4 file. Plus, the help string in this stale entry is
also stale/incorrect.

- simply #include "hwloc.h" to use the external hwloc header
- do use the external hwloc header instead of opal/mca/hwloc/hwloc.h
