Make sure each communicator have a group attached to it. The MPI_COMM_NULL
should have the MPI_GROUP_NULL as a group, in all circumstances.

executable has called MPI_Finalize(). It happens when removing the group
from each of the communicators, that MPI_COMM_NULL doesn't have a group.
Also fix the code from skipping over every other communicator when
freeing the groups.

Minor change to ompi_mca.m4 to move AC_CONFIG_FILES(framework/makefile) in autogen process (instead of configure process), where we still now the actual framework path (instead of guessing using $project/mca/$framework).
This have shown no side effects in our testing. Let us know if this breaks one of your components in some exotic context.

numbers for tuning.
Switch the bookmark_recv to be non-blocking. If this is blocking then for
process counts >= 32 slight process delays were causing cascading performance
delays in the protocol. This lead to checkpoints either taking about 3 sec or
45 sec (or more) for 64 procs due to the cascading delays. With the nonblocking
receive version this is no longer the case we get the speedup we expect for this
part of the protocol.
More tuning to come.

There is a reason that we use the internal type (ompi_file_errhandler_fn) instead of the MPI typedef. When building without MPI-IO support (--disable-mpi-io), the MPI type is not defined, but the internal type IS defined in order to try to keep binary compatibility for apps that don't use MPI-IO.
