ompi_mpi_init(): we no longer *query* the components to see what they
can support -- instead, we *tell* the components what they need to
support (if they can't support it, they should disqualify themselves
from selection).
This involved a bunch of things:
- pass the configure-time-decided OMPI_ENABLE_PROGRESS_THREADS and
OMPI_ENABLE_MPI_THREADS constants to each framework selection
function
- eliminate mca_base_init_select_components()
- eliminate all "allow_multi_user_threads" and "have_hidden_threads"
kinds of arguments and aggregation from various framework selection
and component/module functions
- correctly determine the max MPI thread level that we can support and
limit the final MPI thread level as appropriate during
ompi_mpi_init()
As a side effect, while editing nearly every MPI component I also did
the following:
- found 2 places (gm and ib ptls) where ompi_set_using_threads() was
erroneously being called (I think this is left over kruft from
misunderstandings by the original authors). I removed these.

1. header file and source file protections using #ifdef WIN32
2. new files and directories to support windows functionality
3. appropritate linkage symbols added (OMPI_DECLSPEC) for windows
4. some functions are unimplemented on the windows side. this is mostly
because there might not be need to implement it in windows land. eg., forking
a daemon off
5. Introduced locking mechanisms for windows

code base.
- many (most) mca type names have "component" or "module" in them,
as relevant, just to further distinguish the difference between
component data/actions and module data/actions. All developers
are encouraged to perpetuate this convention when you create
types that are specific to a framework, component, or module
- did very little to entire framework (just the basics to make it
compile) because it's just about to be almost entirely replaced
- ditto for io / romio
- did not work on elan or ib components; have to commit and then
convert those on a different machine with the right libraries and
headers
- renamed a bunch of *_module.c files to *_component.c and *module*c
to *component*c (a few still remain, e.g., ptl/ib, ptl/elan, etc.)
- modified autogen/configure/build process to match new filenames
(e.g., output static-components.h instead of static-modules.h)
- removed DOS-style cr/lf stuff in ns/ns.h
- added newline to end of file src/util/numtostr.h
- removed some redundant error checking in the top-level topo
functions
- added a few {} here and there where people "forgot" to put them in
for 1 line blocks ;-)
- removed a bunch of MPI_* types from mca header files (replaced with
corresponding ompi_* types)
- all the ptl components had version numbers in their structs; removed
- converted a few more elements in the MCA base to use the OBJ
interface -- removed some old manual reference counting kruft
