components to use. This code was rendered obsolete (albiet harmless)
by the MCA base improvements that only open the components that were
specified by each framework's MCA parameter.

We still do an interreduce but it is now followed by an intrascatterv.
This fixes trac:1554.

There was an argument that was barely used, and on return at the PML
level it contained nothing usable. It has been removed, so now we're
using less memory ...

2. fix a bug in the initial communicator creation of llcomm
3. fix a bug which showed up as the result of fixing issue number 2: we have
to check now whether llcomm has really be created before freeing the
according llcomm in hierarch_destruct.

generate an overlap between the different layers. Why four versions? Because
there is right now always the trade-off between using non-blocking operations
on a layer with a trivial, linear algorithm and using the more sophisticaed
algorithms in a blocking manner.
- bcast_intra_seg used the bcast of lcomm and llcomm, similarly
to original algorithm in hierarch. However, it can segment
the message, such that we might get an overlap between the two
layers. This overlap is based on the assumption, that a process
might be done early with a bcast and can start the next one.
- bcast_intra_seg1: replaces the llcomm->bcast by isend/irecvs
to increase the overlap, keeps the lcomm->bcast however
- bcast_intra_seg2: replaced lcomm->bcast by isend/irecvs
to increase the overlap, keeps however llcomm->bcast
- bcast_intra_seg3: replaced both lcomm->bcast and llcomm->bcast
by isend/irecvs
The code is lightly tested, more testing to follow right now.

* 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

hierarch disables itself now if the pml module used is *not* ob1. The reason
is, that the multi-level hierarchy detection algorithm checks the names of the
btl modules used. In case there are no btl's, we would segfault.
Furthermore, three minor changes:
- the 2-level hierarchy detection is now the default (sm vs. everything else
in the world).
- add udapl to the list of protocols checked for by the multi-level hierarch detection
- some of the verbose statements of hierarch were inaccurate. Fixed those comments/messages.

After much work by Jeff and myself, and quite a lot of discussion, it has become clear that we simply cannot resolve the infinite loops caused by RML-involved subsystems calling orte_output. The original rationale for the change to orte_output has also been reduced by shifting the output of XML-formatted vs human readable messages to an alternative approach.
I have globally replaced the orte_output/ORTE_OUTPUT calls in the code base, as well as the corresponding .h file name. I have test compiled and run this on the various environments within my reach, so hopefully this will prove minimally disruptive.

However, no decision logic is changed by this commit so default behavior has not changed. This
is only selectable by runtime parameters.

Need to release the items and the item list after selecting the collective
modules that are being used. Reviewed by Jeff Squyres.
