reap the dead processes when required
* Added logic to ompi_mpi_abort to kill both local and remote groups

#if OMPI_WANT_MPI2_ONE_SIDED and some automake conditionals. Also had
to add some AC_SUBSTs to eliminate part of mpif.h (otherwise the
"external" statements would have made undefined symbols).
All the MPI-2 one-sided functionality (including the skeleton
top-level MPI API functions that only invoke an MPI exception) can be
re-enabled with --enable-mpi2-one-sided.

- Formalize the Windoze output
- The facilities for lazy opening of files were already included in
here (yay foresight!); so just don't open the file aggressively when
we ompi_output_open(); instead, let the first ompi_output() open the
file. This allows the session directory to stay empty (and
therefore removable) if the file is never written to.

name server).
* Add return status message for kill messages from the contact pcm doing
the actual killing so that MPI_Abort or ompi_rte_{kill,term}_{proc,job}
have a useful return value.
* Cleanup the per-started-process local storage in the pcm base to not have
so much code duplication
* Since there are now 4 kill functions (signal or terminate a proc or job)
combine them into one function in the pcm interface. Makes life easier
all around for PCM authors. Already had to combine for the message
transfer.
* Fix race condition in the bootproxy code that was causing it not to
have the right count for number of alive processes

support is included because ROMIO is inherently thread-unsafe.
One possible way to have true asynchronous progress would be to use a
progress thread that wakes up and polls at some frequency when there
are non-blocking IO requests pending. This is pretty icky, though --
it should definitely have an MCA parameter to enable/disable this
functionality, as well as another to control the polling frequency.
This also strengthens the argument that we need a v2 of the io
framework -- one that is not designed to exclusively support ROMIO --
one that does something unimaginably "better" for the parallel MPI-2
IO interface. :-)

* add debuging code for the callback. Since gdb doesn't really like
doing things like waitpid for processes, spin when we are in the
handler in a way that gdb can easily attach and debug

Comm_spawn is now fully functional. I'll send out a separate message about some of the problems encountered, and resulting action items.

w/o threads runs correctly at this stage. fixed errors with using
addresses valid in remote memory scope, not local memory scope.
