started to add static (fixed if) statement based decision rules based on gigE numbers
added mca params so that a user can force a certain algorithm/segment/topo on a per collective basis
(this is not in the fixed call path but only in the dynamic (at com create) call path).
(these params can be used by test suites such as OCC to choice which algorithm they are using).

they are actually disabling.
This should go to the 1.0 branch

This takes care of Troy's first segfault problem, and compile errors that will likely happen as soon as Ken applies George's patch and runs make again.

Note, we are failing the ring tests in the intel p2p test suite, but we seem
to fail the same tests under the current trunk.. will look into this further.

convertor (when prepared) increase the reference count on the used datatype. This reference count
will be released only when the OBJ_DESTRUCT is called on a convertor. However, having to call
OBJ_CONSTRUCT and OBJ_DESTRUCT on each request every time we want to use it (even when it come
from the cache) is an expensive operation. This can be avoided is the OBJ_DESTRUCT will leave the
convertor in exactly the same state as OBJ_CONSTRUCT. With this approach we just have to call
OBJ_CONSTRUCT for each convertor once when we initially create the request.

memory initialization, call opal_progress() to push any pending events
around and possibly yield the processor if nothing entertaining is happening.
This should probably go to the 1.0 branch.

--with-devel-headers is given to configure:
* allocator, rcache, and mpool were putting things in the wrong place
* timer wasn't installing the inline implementations at all

really crappy job of trying to emulate the inline assembly mode of GCC (and will
completely rewite the assembly, which seems to be bad in my opinion). GCC and
the AIX assembler don't see eye-to-eye on what GCC emits when doing inline
assembly. That's two compilers and no actual working support. So just punt and
fall back to XLC inline assembly or non-inlined assembly.

number of collective operations and simplifies the logic significantly.
- introducing a special case if size of comm == 1, avoiding thus collective
operations as well ( i.e. no need for hierarchies)
- fix for an unsymmetric case. Still to be tested.

own sequence.
- if a write doesn't complete, need to check for non-blocking case..

AC_CHECK_FUNCS, so #ifdef is the correct preprocessor conditional here
(because it will be defined or not -- not always defined to, say, 0 or
1).

originally suggested by Ralf Wildenhues, to try to speed autogen, configure,
and make (and possibly even make install). Use automake's include directive
to drastically reduce the number of Makefile files (although the number of
Makefile.am files is the same - most are just included in a top-level
Makefile.am). Also use an Automake SUBDIRs feature to eliminate the
dynamic-mca tree, which was no longer really needed. This makes adding
a framework easier (since you don't have to remember the dynamic-mca
tree) and makes building faster (as make doesn't have to recurse through
the dynamic-mca tree)

First cut on barrier (which from my perspective does not make sense from the
performance point of view) and on allreduce (which might make sense),

done. This version also doesn't break ompi (at least if its not chosen :-) ).
New features compared to the version from last Thursday (where bcast and
reduce seemed to work in most scenarios):
- clearer internal infrastructure
- ability to handle all root processes with a (hopefully) minimal number of
local leader communicators.
