1. minor modification to include two new opal MCA params:
(a) opal_profile: outputs what components were selected by each framework
currently enabled for most, but not all, frameworks
(b) opal_profile_file: name of file that contains profile info required
for modex
2. introduction of two new tools:
(a) ompi-probe: MPI process that simply calls MPI_Init/Finalize with
opal_profile set. Also reports back the rml IP address for all
interfaces on the node
(b) ompi-profiler: uses ompi-probe to create the profile_file, also
reports out a summary of what framework components are actually
being used to help with configuration options
3. modification of the grpcomm basic component to utilize the
profile file in place of the modex where possible
4. modification of orterun so it properly sees opal mca params and
handles opal_profile correctly to ensure we don't get its profile
5. similar mod to orted as for orterun
6. addition of new test that calls orte_init followed by calls to
grpcomm.barrier
This is all completely benign unless actively selected. At the moment, it only supports modex-less launch for openib-based systems. Minor mod to the TCP btl would be required to enable it as well, if people are interested. Similarly, anyone interested in enabling other BTL's for modex-less operation should let me know and I'll give you the magic details.
This seems to significantly improve scalability provided the file can be locally located on the nodes. I'm looking at an alternative means of disseminating the info (perhaps in launch message) as an option for removing that constraint.

1. fix a bug in pml_ob1_recvreq/sendreq.c, buffer was made defined where the request has already been released.
2. complete memchecker support for collective functions.
3. change the wrongly spelled function name of memchecker, i.e. '*_isaddressible' should be '*_isaddressable'

Valgrind header files if they weren't already in the compiler's
default header file search path. This commit fixes that typo and adds
a little more infrastructure (via an AC_SUBST) to pass in the relevant
CPPFLAGS to the build system for the valgrind memchecker component.

There is still a problem with OpenIB and threads (external to C/R functionality). It has been reported in Ticket #1539
Additionally:
* Fix a file cleanup bug in CRS Base.
* Fix a possible deadlock in the TCP ft_event function
* Add a mca_base_param_deregister() function to MCA base
* Add whole process checkpoint timers
* Add support for BTL: OpenIB, MX, Shared Memory
* Add support Mpool: rdma, sm
* Sundry bounds checking an cleanup in some scattered functions

Bring in a new version of PLPA (v1.2b2) with some new capabilities for
offline processors and mapping of the Nth processor/socket/core to its
corresponding Linux processor/socket/core ID.
(Sorry for the configure change in the middle of the day, folks -- I
need it to be able to continue to integrate paffinity changes for
#1435...)

* Make the creation of the build dir for the man pages a bit more
robust (thanks to suggestions from Ralf W.).
* Only distribute the .Xin files, not the .X man pages themselves.
* Make the .X files depend on opal_config.h so that if you re-run
configure and change opal_config.h (e.g., a new version), the man
pages should get rebuilt.
* Man pages are now cleaned with "distclean", not "maintainer-clean".
* Fix a typo in opal_crs.7in.
* Udpate make_dist_tarball to update "date" in the VERSION file.
* Make make_dist_tarball a bit friendlier to hg checkouts.

* Make the results of the top-level configure.ac test for
_SC_NPROCESSORS_ONLN be cached so that we can check for it
elsewhere (e.g., opal/mca/paffinity/posix/configure.m4)
* Update top-level configure.ac test for _SC_NPROCESSORS_ONLN: stamp
out another AC_TRY_COMPILE
* Ensure paffinity:posix doesn't even try to compile if we don't
have _SC_NPROCESSORS_ONLN
* Minor style updates

* add "register" function to mca_base_component_t
* converted coll:basic and paffinity:linux and paffinity:solaris to
use this function
* we'll convert the rest over time (I'll file a ticket once all
this is committed)
* add 32 bytes of "reserved" space to the end of mca_base_component_t
and mca_base_component_data_2_0_0_t to make future upgrades
[slightly] easier
* new mca_base_component_t size: 196 bytes
* new mca_base_component_data_2_0_0_t size: 36 bytes
* MCA base version bumped to v2.0
* '''We now refuse to load components that are not MCA v2.0.x'''
* all MCA frameworks versions bumped to v2.0
* be a little more explicit about version numbers in the MCA base
* add big comment in mca.h about versioning philosophy

Kinda found by MTT. MTT calls 'ompi_info --all --parsable' and it was livelocked and had to be killed by hand.
I'm going to push this one to Jeff to push to v1.3 since he did the original implementation and should check this code.

Modify the odls to remove a (size_t) typecast in front of the num_processors variable just in case it is returned negative. This usually is accompanied by an opal_error, so this shouldn't make any difference - but it is more technically correct.
This commit was SVN r19008.
* Fix linux paffinity component to make a "best" guess when PLPA
can't find topology information in the Linux kernel. That is, if
PLPA can't tell us the max_processor_id, just assume that it's the
same as the number of processors. If you have a more complex
system than that (e.g., you have holes in your available processor
IDs), you'll likely be running a Linux kernel that supports the
topology information, and this problem won't happen.
* Make sure to conver the return codes from PLPA to OPAL_ERR* codes.
