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

-- non-blocking stuff is pending some changes in the top-level

- added src/mpi/f77/strings.[ch] for f<-->c string conversions
- added src/mpi/f77/constants* for instiantiating and providing macros
to check for the various fortran address "constants" (read the
comments in this file -- it's quite complicated, unfortunately :-\ ):
- MPI_BOTTOM
- MPI_ARGV_NULL
- MPI_ARGVS_NULL
- MPI_ERRCODES_IGNORE
- MPI_STATUS_IGNORE
- MPI_STATUSES_IGNORE
- updated fortran MPI_COMM_SET_NAME and MPI_COMM_GET_NAME to check
string handling
- updated fortran MPI_RECV to check MPI_STATUS_IGNORE handling
- updated fortran MPI_COMM_SPAWN to check string and MPI_ARGV_NULL and
MPI_ERRCODES_IGNORE handling
- partially modified src/mpi/f77/prototypes_mpi.h to account for
string length parameters passed by the fortran compiler; more work to
be done there
- backed out a silly previous change in send_f.c by me (duh)
- updated fortran MPI_COMM_DUP and MPI_COMM_FREE to check int<-->fint
macros

In order to get consistent behaviour on linux with various gcc versions,
I am defining _GNU_SOURCE in ompi_config.h and changing the definition
of asprintf, etc.
Problems:
1) autoconf was defining _GNU_SOURCE for its tests, but we were not
setting it
2) g++ sets it by default (I think)
3) some version of gcc set it by default
If somebody knows a consistent solution for these problems then we can
revert to not setting it.

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).

- 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".

real commit of the collectives. MPI_SCAN and MPI_EXSCAN are still not
implemented, but lots of other things are in the critical path and
holding up other people, so it's ok to commit without them:
- better checks for sizes in configure, and add defaults for fortran
sizes if we don't have a fortran compiler
- fix some logic that was accidentally broken for size checks for the
file type offset_t
- add some C equivalent types for fortran's complex and double complex
(for use in internal reduction/op functions)
- additionals and slight reorganization of ompi_mpi_init()
ompi_mpi_finalize()
- fully implement all top-level MPI collective calls, including all
param checking for both intra- and inter-communicators (woof)
- change the communicator_t type for stuff that we need in coll, and
update all references throughout the code base to match
- all kinds of updates to the coll framework base
- next cut of the basic coll module -- has all intracommunicator
collectives implemented except scan and exscan (see note above).
All intercommunicator functions return ERR_NOT_IMPLEMENTED.
- MPI_Op is a fixed implementation -- not component-ized yet. So
there are generic C loops for all implementations.
