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.

We've been fighting the battle of trying to create a regex generator and
parser that can handle arbitrary hostname schemes - without long-term
success. The worst of it is that there is no way of checking to see if
the computed regex is correct short of parsing it and doing a
character-by-character comparison with the original string. Ugh...there
has to be a better solution.
One option is to investigate using 3rd-party regex libraries as
those are coming from communities whose sole focus is resolving that
problem. However, someone would need to spend the time to investigate
it, and we'd have to find a license-friendly implementation.
Another option is to quit beating our heads against the wall and just
compress the information. It won't be as much of a reduction, but we
also won't keep hitting scenarios where things break. In this case, it
seems that "perfection" is definitely the enemy of "good enough".
This PR implements the compression option while retaining the
possibility of people adding regex-generating components. The
compression code used in ORTE is consolidated into the opal/compress
framework. That framework currently held bzip and gzip components for
use in compressing checkpoint files - since we no longer support C/R, I
have .opal_ignore'd those components.
However, I have left the original framework APIs alone in case someone
ever decides to redo C/R. The APIs of interest here are added to the
framework - specifically, the "compress_block" and "decompress_block"
functions. I then moved the ORTE zlib compression code into a new
component in this framework.
Unfortunately, the framework currently is a single-select one - i.e.,
only one active component at a time. Since I .opal_ignore'd the other
two and made the priority of zlib high, this isn't a problem. However,
if someone wants to re-enable bzip/gzip or add another component, they
might need to transition opal/compress to a multi-select framework.
Included changes:
* Consolidate the compression code into the opal/compress framework
* Move the ORTE zlib compression code into a new opal/compress/zlib
component
* Ignore the bzip and gzip components in opal/compress framework
* Add a "compress_base_limit" MCA param to set the threshold above which
we compress data - defaults to 4096 bytes
* Delete stale brucks and rcd components from orte/grpcomm framework
* Delete the orte/regx framework
* Update the launch system to use opal/compress instead of string regex
* Provide a default module if no zlib is available
* Fix some misc multi-node issues
* Properly generate the nidmap in response to a "connection warmup"
message so the remote daemon knows the children it needs to launch.
* Remove stale references to orte_node_regex
* opal_byte_object_t's are not OPAL objects - properly release allocated
memory.
* Set the topology
* Currently only handling homogeneous case
* Update the compress framework files to conform
* Consolidate open/close into one "frame" file. Ensure we open/close the
framework

Update the OPAL_CHECK_OFI configury macro:
- Make it safe to call the macro multiple times:
- The checks only execute the first time it is invoked
- Subsequent invocations, it just emits a friendly "checking..."
message so that configure output is sensible/logical
- With the goal of ultimately removing opal/mca/common/ofi, rename the
output variables from OPAL_CHECK_OFI to be
opal_ofi_{happy|CPPFLAGS|LDFLAGS|LIBS}.
- Update btl/ofi, btl/usnic, and mtl/ofi for these new conventions.
- Also, don't use AC_REQUIRE to invoke OPAL_CHECK_OFI because that
causes the macro to be invoked at a fairly random time, which makes
configure stdout confusing / hard to grok.
- Remove a little left-over kruft in OPAL_CHECK_OFI, too (which
resulted in an indenting change, making the change to
opal_check_ofi.m4 look larger than it really is).
Thanks Alastair McKinstry for the report and initial fix.

Now that all components that use libibverbs are gone, remove
OPAL_CHECK_VERBS and the confusingly-named OPAL_CHECK_OPENFABRICS
(which really just checked for verbs things -- not all the possible
OpenFabrics APIs/libraries).
The only code left in Open MPI that calls verbs is hwloc -- and that's
just the APIs that takes an IBV device and returns topological
information about it. Since nothing in the Open MPI code base uses
the "ibv_*" API any more, we have no need for this hwloc functionality
so we'll even remove the --with-verbs configure options.
