- move files out of toplevel include/ and etc/, moving it into the
sub-projects
- rather than including config headers with <project>/include,
have them as <project>
- require all headers to be included with a project prefix, with
the exception of the config headers ({opal,orte,ompi}_config.h
mpi.h, and mpif.h)

the code to use the new PML send flags.

this was implemented using a chain (tree followed with pipeline) by setting the chain fanout to a factor of size etc but the chain datastructure was fixed in length and if exceeded the topo create returned a null which isn't helpfull in cid next function of comdup...
Anyway two fixes, first we do have a real linear function so changed the decision function and second altered the
topo chain create to force chain fanouts of less than 1 to 1 and fanouts bigger than max to max.
next check in will change chain to dynamically allocd array (reallocable) but we shouldn't ever use a chain fanout for a linear tree anyway.
(lession must rerun all tests for all data sizes when changing decision functions)

(apparently we've been doing this in opal and orte, but not in ompi
yet). All public symbols begin with "ompi_coll_tuned_" (not
mca_coll_tuned_) except the component struct. Now this component
passes the illegal symbol report with no hits.

the baseline collective component. Please report any problems with
this component.
If you run into problems with this component, you can disable it with:

modules, if its priority is zero (the default value). Reason for that is
+ if there is no other module with a priority > 0, the hierarchical
collective module has a problem anyway, since it has to rely on the coll
modules of the subcommunicators. On the other hand, if its priority is
zero, it won't be chosen anyway, and we can simply save the
allreduce/allgather and comm_split operations which might occur during
hierarchy detection.
+ to improve the startup times until we have the modex thing which we
discussed with Jeff and Tim in Knoxville in place
- adding an mca parameter indicating a symmetric configuration. This can
speed up startup times, since each process can conclude from its data onto
the data of the other processes -> no need for the allreduce operations. Per
default this parameter is set to "no".

stage fairly confident that
- it works in most scenarious (with symmetric hierarchies, with asymmetric
hierarchies, wihout hierarchies - it just removes itself)
- it does not create too many problems (I am not aware of any at least)
- it does not slow down startup anymore dramatically (thanks to the fixes of
Brian, Jeff, Tim and a significant reduction in the number of collective
operations in the comm_query)
Any feedback is highly welcome.

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).

- 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.

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),
