opal_process_name_t is an uint64_t which is not equivalent to
an unsigned long on 32 bits systems.
this is now parsed as an unsigned long long.
This commit was SVN r32592.
Make the checks for macro weak symbols be equivalent to the checks for
weak symbols.
Also fix up several OSHMEM configure checks:
* fix an errant AC_MSG_REQUEST
* don't check for profiling ability during configure options checks.
Instead, defer it to later, when we have weak symbol check results.
* don't directly call _FOO macros from the top level
* make setting up OSHMEM profiling similar to MPI profiling: create
OSHMEM_SETUP_PROFILING macro
* cache the results of checking for macro weak symbols (for parity
with the weak symbol check -- although we should really
revisit/audit the whole cache-checking scheme throughout all m4
code; it may well be inconsistently used)
* add some more [] m4 quoting, even in the original C weak symbols test
* style: fix some whitespace errors

Per #4874, code review revealed a possible race condition in the
module struct and the connectivity agent. Move the setup of the
connectivity agent listener until the module struct has been fully
setup.
This commit was SVN r32573.
When no components were able to be found, btl_base_select() was
showing the wrong help message -- one that indicated that a specific
component could not be found. And it left off a string argument, so
the end of the help message was garbage.
This commit creates a new help message for this case and updates the
show_help call to use the new message.

WHAT: Merge the PMIx branch into the devel repo, creating a new
OPAL “lmix” framework to abstract PMI support for all RTEs.
Replace the ORTE daemon-level collectives with a new PMIx
server and update the ORTE grpcomm framework to support
server-to-server collectives
WHY: We’ve had problems dealing with variations in PMI implementations,
and need to extend the existing PMI definitions to meet exascale
requirements.
WHEN: Mon, Aug 25
WHERE: https://github.com/rhc54/ompi-svn-mirror.git
Several community members have been working on a refactoring of the current PMI support within OMPI. Although the APIs are common, Slurm and Cray implement a different range of capabilities, and package them differently. For example, Cray provides an integrated PMI-1/2 library, while Slurm separates the two and requires the user to specify the one to be used at runtime. In addition, several bugs in the Slurm implementations have caused problems requiring extra coding.
All this has led to a slew of #if’s in the PMI code and bugs when the corner-case logic for one implementation accidentally traps the other. Extending this support to other implementations would have increased this complexity to an unacceptable level.
Accordingly, we have:
* created a new OPAL “pmix” framework to abstract the PMI support, with separate components for Cray, Slurm PMI-1, and Slurm PMI-2 implementations.
* Replaced the current ORTE grpcomm daemon-based collective operation with an integrated PMIx server, and updated the grpcomm APIs to provide more flexible, multi-algorithm support for collective operations. At this time, only the xcast and allgather operations are supported.
* Replaced the current global collective id with a signature based on the names of the participating procs. The allows an unlimited number of collectives to be executed by any group of processes, subject to the requirement that only one collective can be active at a time for a unique combination of procs. Note that a proc can be involved in any number of simultaneous collectives - it is the specific combination of procs that is subject to the constraint
* removed the prior OMPI/OPAL modex code
* added new macros for executing modex send/recv to simplify use of the new APIs. The send macros allow the caller to specify whether or not the BTL supports async modex operations - if so, then the non-blocking “fence” operation is used, if the active PMIx component supports it. Otherwise, the default is a full blocking modex exchange as we currently perform.
* retained the current flag that directs us to use a blocking fence operation, but only to retrieve data upon demand

Thanks to Ashley Pittman for pointing the modex should now be zero'ed

providing a netmask of 0 to opal_net_samenetwork results in everything
looking like it is on the same network. Hence, we were not retaining any
of the alternative addresses, so we had no other way to check them.
