technically speaking, this is a cosmetic change, but having the wrong
parameter names was extremely confusing -- it took me a while (and I
had to cross-reference MPI-1) to figure out that they were wrong, and
I was thinking about the functions incorrectly as a result. Our mpi.h
should have the Right names in order to not confuse users (and
developers!).

#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.

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. :-)

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

Better memory handling, faster it adapt it's behaviour to the low level driver and to the
datatype representation. However, only the TCP driver has been modified to fit the new engine.
For Fortran the MPI_DATATYPE_NULL is now registered at index 0 in the translation table.

- move the attribute init section in ompi_mpi_init() down below where
communicators are setup (we need MPI_COMM_WORLD to be setup before
attributes and keyvals are setup)
- removed confusing extra wrapper class around ompi_hash_table_t;
looks like it was a victim of slow eroding of members so I put took
it out back and put it out of its misery
- added preliminary definitions for all the pre-defined keyvals.
Still need more work here to assign their initial values, but I
think Edgar was running into an atrribute problem and it may have
been that the pre-defined attrs didn't yet exist.
- removed some LAM-specific predefined keyvals from mpi.h

includes the romio component. Only blocking operations are supported
-- non-blocking stuff is pending some changes in the top-level
progression engine, and some threaded issues need to be worked out.

somewhat tied together and I'd rather have a consistent commit rather
than several smaller commits that individually break the tree:
- first cut of src/file/file.c: MPI_File handling. More to come here.
- tweaked MPI_Info handling a bit: cause MPI_Info_f2c to invoke error
handler if provided index is out of range (vs. returing
MPI_INFO_NULL without invoking an error handler)
- moved general MPI MCA params off into their own .h and .c file (so
that ompi_info can call it and therefore display MPI MCA params)
- first [abbreviated] cut of src/mca/io/base/* -- much more to come
here; stripped down to basics for this commit
- filled in a small number of MPI_File* functions for testing purposes
- updated a bunch of doxygen docs
--> Unresolved questions about MPI_ERRORS_RETURN, MPI_ERRORS_ABORT,
and MPI::ERRORS_THROW_EXCEPTIONS because of vagueness in MPI
standard -- Edgar and I are discussing what to do here
--> Unresolved questions about what to do in a case like this:
MPI_File_open(..., &file);
MPI_File_close(&file);
MPI_File_read(..., &file);
because MPI-2:9.7 says that the default error handler on MPI_File
handles is MPI_ERRORS_RETURN -- we can't even print a warning
here! This certainly violates the Law of Least Astonishment for
MPI users (who certainly expect MPI functions that fail to
complain loudly and to abort by default).
This commit was SVN r2136.
- fix a few bugs
- convert/add doxygen comments for internal info functions in
src/info/info.h (some comments were originally in src/info/info.c)
- make it thread safe
- make MPI_INFO_NULL be a real object (vs ((struct ompi_info_t*) 0))
- add error checking into top-level MPI functions
- add support in MPI_Info for "never freeing MPI handles" as a form of
debugging i.e., check if see if you accidentally use a freed handle)
- add support for "print out a list of un-freed MPI_Info handles
during MPI_FINALIZE"

from the "LAM/MPI" -> "Open MPI" name change that didn't convert
properly. So this commit fixes all instances of "OMPI/MPI" to "Open
MPI".
This commit was SVN r1924.
in src/datatype/dt_module.c. Now we can easily test for all the correct
flags on send and receive (like datatype commit ...)
This commit was SVN r1768.
if we're going to suport non-ANSI compilers (in which case we would
need a corresponding #else block with a set of non-ANSI typedefs),
which we're not going to do. :-)
This commit was SVN r1102.
