* Major rework of Portals to better match Red Storm and hopefully get
better performance:
- Always assume there is only one module (since there are no machines
on the planet with more than one Portals interface)
- make progress all one function rather than dispatching to other
functions and dispatch on event type, not comm type
- remove polling of unneeded events

Change all the places where they are used to fit the new name.
Remove the code to check the remote arch from the PML. We will have a GPR mechanism
in ompi_mpi_initialize to do that.

the message is no longer pending
* Try to push out new messages whenever we finish a send, whether it
worked or not. Means that in the case where the other side has too
many sends pending, we'll constantly retry one (and only one, once the
pending number is reached) message until goodness returns
* Make some warnings only happen in verbose case, as they are mainly
diagnostics

support in OMPI. Currently only enables/disables the architecture
sharing modex in ob1 pml.
* Add sds framework to ompi_info
* Figure out table ids to use for Portals BTL at configure time, since
we should use 30 & 31 on Red Storm, but the reference implementation
only supports 0-8.
* Some bug fixes in Portals UTCP sds
This commit was SVN r6650.
- only call sched_yield if it exists
- don't fail out if modex doens't work in ob1
- bunch of fixes for Portals BTL
- add cnos rml component
- add NULL gpr component (should only be used if replica AND proxy
fail to load)

* remove the recv fragment code, since it really isn't needed
* handle memory descriptor binding a bit more sanely, and use
thresholds so that Portals does the unlink for us, when it feels
like it.
This commit was SVN r6575.
* change all the opal_output_verbose calls in the critical path to
OPAL_OUTPUT_VERBOSE so that they are pre-processed out if debugging
is not enabled
* remove stub code

"run-time" api for the reference implementation.
* Make the non-modex utcp and redstorm compat code do the same things in
the same order

associated with the descriptor is ours again once the callback function
returns. Make it so - probably can optimize out some of the stuff I
did when I mistakenly thought the descriptor free() was called on the
passed descriptor
* Fix some dumb accounting errors with MD usage for unexpected receives

IBM tests, but see same segfaults / assets in sm btl.
* Add prepare_src implementation so that we can send multiple fragments of
large messages
* Add queuing of sends if either there are too many outstanding sends
(we have to limit this so that we don't have more sends pending than
we could get acks for) or if we get an ack with a 0 byte mlength,
which means the remote side dropped the message on us.
Still need to valgrind to make sure I'm not leaking resources

Red Storm. Add stub functions to ompi_config_bottom.h when they are
around
* Add protection for a bunch of #include <netinet/in.h>s
* Fix up the Portals BTL so that it compiles on Red Storm and has the
right mojo for initialization on Red Storm
* Add some important comments to ompi_check_package and mvapi configures
* Add support for platforms without getpwuid() (aka, Red Storm).

components to succeed with --enable-dist. Instead, just add them to
all_components and make dist will still work - we're going to stamp out
the Makefiles no matter what
* Add missing header to ob1 pml for make dist
* Clean up the Portals BTL configure code

frameworks, and components without configure scripts instead of
hard-coded shell variables (for projects and frameworks) and
shell variable building (for components).
* Add 3rd category of component configuration (in addition to configure
scripts and no-configured components): configure.m4 components. These
components can only be built as part of OMPI (like no-configure), but
can provide an m4 file that is run as part of the main configure
script. These macros can set whether the component should be built,
along with just about any other configuration wanted. More care must
be taken compared to configure components, as doing things like setting
variables or calling AC_MSG_ERROR now affects the top-level configure
script (so calling AC_MSG_ERROR if your component can't configure
probably isn't what you want)
* Added support to autogen.sh for the configure.m4-style components,
as well as building up the m4_define lists ompi_mca.m4 now expects
* Updated a number of macros to be more config.cache friendly (both
so that config.cache can be used and so the test can be quickly
run multiple times in the same configrue script):
- ompi_config_asm
- c_weak_symbols
- c_get_alignment
* Added new macros to be shared when configuring components:
- ompi_objc.m4 (this actually provides AC_PROG_OBJC - don't ask...)
- ompi_check_xgrid
- ompi_check_tm
- ompi_check_bproc
* Updated a number of components to use configure.m4 instead of
configure.stub
- btl portals
- io romio
- tm ras and pls
- bjs, lsf_bproc ras and bproc_seed pls
- xgrid ras and pls
- null iof (used by tm)
