This flag is inherited by all datatypes create with unavailable datatypes. Basically, we let the user create the wrong datatype but we dont let him using it for any pt2pt communications or any pack/unpack.

restoring the PMPI version. A variety of reasons for this:
- mpi.h was blinding using inline in a C header without the configrue mojo
properly set it, as mpi.h doesn't include ompi_config.h. This eventually
would have caused a borked build.
- mpi.h and mpif.h were never updated to not include PMPI_W{tick,time} as
a proper prototype
- The C++ and F90 bindings didn't do the right things when there was no
PMPI version of the C call, but profiling was enabled
- Since we only use gettimeofday, the function call overhead really doesn't
matter
This should probably go to the 1.0 branch

REDUCE_SCATTER to more thoroughly check the datatype/op combination
to see if it's valid or not. If it's not, print a meaningful error
message rather than "Invalid MPI_Op" indicating what specifically
was wrong (therefore hopefully helping users track down where in the
code the problem is, and/or telling us that there's a reduction
operation combo that we don't support that we should)
- The check for whether a datatype is intrinsic needed to be updated
-- it's not sufficient to check that dtype->id < DT_MAX_PREDEFINED;
you really need to check the PREDEFINED flag on the datatype.
Thanks to George for this fix (only intrinsics have a meaningful
value in dtype->id).

at the top-level MPI API function. This allows two kinds of
scenarios:
1. MPI_Ireduce(..., op, ...);
MPI_Op_free(op);
MPI_Wait(...);
For the non-blocking collectives that we're someday planning -- to
make them analogous to non-blocking point-to-point stuff.
2. Thread 1:
MPI_Reduce(..., op, ...);
Thread 2:
MPI_Op_free(op);
Granted, for #2 to occur would tread a fine line between a correct and
erroneous MPI program, but it is possible (as long as the Op_free was
*after* MPI_reduce() had started to execute). It's more realistic
with case #1, where the Op_free() could be executed in the same thread
or a different thread.

AM_INIT_AUTOMAKE, instead of the deprecated version.
* Work around dumbness in modern AC_INIT that requires the version
number to be set at autoconf time (instead of at configure time, as
it was before). Set the version number, minus the subversion r number,
at autoconf time. Override the internal variables to include the r
number (if needed) at configure time. Basically, the right thing
should always happen. The only place it might not is the version
reported as part of configure --help will not have an r number.
* Since AM_INIT_AUTOMAKE taks a list of options, no need to specify
them in all the Makefile.am files.
* Addes support for subdir-objects, meaning that object files are put
in the directory containing source files, even if the Makefile.am is
in another directory. This should start making it feasible to
reduce the number of Makefile.am files we have in the tree, which
will greatly reduce the time to run autogen and configure.

the values to the PML structure. This will allow PMLs that want to do
hardware matching at the cost of a smaller range of valid tags and cids.
Updated all the places that used the MPI_TAG_UB_VALUE constant to instead
look at the pml struct.

Any non-blocking P2P function should set the request to something else
then MPI_REQUEST_NULL, when passed a source/dest of MPI_PROC_NULL.
Introduce a new ompi_request_empty, which returns the
MPI_SOURCE=MPI_PROC_NULL, MPI_TAG=MPI_ANY_TAG, count=0 as specified by
the MPI-standard.
