MPI-4 is finally cleaning up its language: an MPI "exception" does not
actually exist. The only thing that exists is an MPI "error" (and
associated handlers). This commit replaces all relevant uses of the
word "exception" with "error". Note that this is still applicable in
versions of the MPI standard less than MPI-4.0 (indeed, nearly all the
cases fixed in this commit are just changes to comments, anyway).
One exception to this is the Java bindings, where there's an
MPIException class. In hindsight, it probably should have been named
MPIError, but changing it now would break anyone who is using the Java
bindings.

The C++ bindings were removed a while ago;
MPI::ERRORS_THROW_EXCEPTIONS and MPI_ERRORS_THROW_EXCEPTIONS no longer
exist.

The btl/ofi does not currently utilize the common ofi include/exclude
list. Added verification code similar to the mtl/ofi that will check if
the info object is in the include or exclude list. If it isn't in the
include list or is in the exclude list, validate_info will return
OPAL_ERROR. The btl/ofi will no longer pass a provider name as a hint
when calling getinfo, instead filtering the provider during
validate_info.
This patch also moves the is_in_list MTL function into common code and
adds additional debugging output to the BTL to match the MTL standard.

The default algorithm selections were out of date and not performing
well. After gathering data from OMPI developers, new default algorithm
decisions were selected for:
allgather
allgatherv
allreduce
alltoall
alltoallv
barrier
bcast
gather
reduce
reduce_scatter_block
reduce_scatter
scatter
These results were gathered using the ompi-collectives-tuning package
and then averaged amongst the results gathered from multiple OMPI
developers on their clusters.

It is important to have the mpi_f08 Type(MPI_Status) be the same
length (in bytes) as the mpif.h status (which is an array of
MPI_STATUS_SIZE INTEGERs). The reason is because MPI_Status_ctof()
basically does the following:
MPI_Fint *f_status = ...;
int *s = (int*) &c_status;
for i=0..sizeof(MPI_Status)/sizeof(int)
f_status[i] = c_status[i];
Meaning: the Fortran status needs to be able to hold as many INTEGERs
are there are C int's that can fit in sizeof(MPI_Status) bytes.
This is because a Fortran INTEGER may be larger than a C int (e.g.,
Fortran 8 bytes vs. C 4 bytes). Hence, the assignment on the Fortran
side will take sizeof(INTEGER) bytes for each sizeof(int) bytes in the
C MPI_Status.
This commit pads out the mpi_f08 Type(MPI_Status) with enough INTEGERs
to make it the same size as an array of MPI_TYPE_SIZE INTEGERs.
Hence, MPI_Status_ctof() will work properly, regardless of whether it
is assinging to an mpi_f08 Type(MPI_Status) or an mpif.h array of
MPI_STATUS_SIZE INTEGERs.
Thanks to @ahaichen for reporting the issue.

This commit updates the btl interface to change the parameters
passed to receive callbacks. The interface used to pass the tag,
a btl base descriptor, and the callback context. Most of the
values in the btl base descriptor were unused and only helped
simplify the callbacks from the self btl. All of the arguments
have now been replaced with a single receive callback descriptor.
This descriptor contains the incoming endpoint, data segment(s),
tag, and callback context. All btls have been updated to use
the new callback and the btl interface version has been bumped
to v3.2.0.
As part of this change the descriptor argument (and the segments
contained within it) have been marked as const. The were treated
as const before but this change could allow the compiler to make
better optimization decisions and will enforce that the callback
does not attempt to change the data in the descriptor.
