for dynamic selection of cpc methods based on what is available. It
also allows for inclusion/exclusions of methods. It even futher allows
for modifying the priorities of certain cpc methods to better determine
the optimal cpc method.
This patch also contains XRC compile time disablement (per Jeff's
patch).
At a high level, the cpc selections works by walking through each cpc
and allowing it to test to see if it is permissable to run on this
mpirun. It returns a priority if it is permissable or a -1 if not. All
of the cpc names and priorities are rolled into a string. This string
is then encapsulated in a message and passed around all the ompi
processes. Once received and unpacked, the list received is compared
to a local copy of the list. The connection method is chosen by
comparing the lists passed around to all nodes via modex with the list
generated locally. Any non-negative number is a potentially valid
connection method. The method below of determining the optimal
connection method is to take the cross-section of the two lists. The
highest single value (and the other side being non-negative) is selected
as the cpc method.

use the STL. This is the first step in removing the STL from the C++
bindings (Solaris has 2 versions of the STL; if OMPI uses one and an
MPI application wants to use another, Bad Things happen).
The main idea is to wrap up the C++ callback function pointers and the
user's extra_state into our own struct that is passed as the
extra_state to the C keyval registration along with the intercept
routines in intercepts.cc. When the C++ intercepts are activated,
they unwrap the user's callback and extra state and call them.
It got a little more complicated than that, however:
* I realized that we were returning errors back from
Comm::create_keyval() incorrectly, so I fixed that.
* Instead of using STL maps to store associations, we now use an
opal_list_t which has to be guaranteed to be initialized correctly
and only once in a multi-threaded environment.
* Because of whackyness in the C++ bindings, it is possible to call
Comm::Create_keyval with C callbacks (!). If both registered
callbacks are C functions, then ensure to avoid all the C++
machinery.

Also introduces work in progress "convertor" sender based copy algorithm. This algorithm cannot be selected without other modifications in the convertor (not currently available in trunk). The default old synchronous copy algorithm is selected by default.

* Remove duplicate %{_sysconfdir} in the % files sections when
building the sub-packages.
* When building the sub-packages, ensure that devel.files also picks
up the F90 module.
* Hard-code the directory name "openmpi" into _pkglibdir (vs. using
%{name}) because the OMPI code base has it hard-coded as well.
Thanks to Jim Kusznir for noticing the problem.

high prio QPs and low prio QPs) and because not all of them are polled each time
progrgess() is called (to save on latency) starvation is possible. The commit
fixes this. Now each channel is polled, but higher priority channels are polled
more often. Three new parameters are introduced that control polling ratios
between different channels.

ompi_pointer_array.c:ompi_pointer_array_set_item() was slightly
changed such that the "find the next open slot when the requested
index was already open" logic was no longer right -- since the new
lowest_free value is not set until ''after'' we look for the next open
slot, we need to start searching for the new lowest_free slot at the
(index+1) position (not the index position).
