Implementation of MPI-3 window info query routines.

Reviewer: balaji

This adds a simple implementation for request-based RMA operations.  The
implementation uses generalized requests as follows:

 1. Insert operation into the RMA ops list
 2. Create a generalized request
 3. When the request is polled, flush the window and mark completed

The RMA op dispatch macro was previously defined in a private header used by
the high level routines.  This has been moved to mpiimpl.h to join the rest of
the RMA op table code.   This will allow other routines to dispatch RMA ops at
the ADI correctly.

[svn-r10377] More fixes for inter-language attribute use.  Tested on x86 and 64-bit SPARC; there are still errors because of the incorrect use of int where MPI_Fint is needed, but this will work for most users, and the MPI_Fint case has been removed from MPI-3

By setting "indent-tabs-mode:nil" we should hopefully begin to slowly
squeeze out hard tabs from the source without a disruptive (to
downstream projects) whitespace-fixing change.

The new ABI string is 8:0:0 because we changed the prototype of
MPIX_Win_allocate_shared since rc1.  The rc2 release should have also
had this string, but I forgot to update the version.m4 file before
cutting the tarball.

The information returned by MPI_Type_get_contents was incorrect for the
new MPI-3 routine, MPIX_Type_create_hindexed_block.  This commit fixes
the bug and adds a regression test for it ("hindexed_block_contents").

In several places, after checking for a parameter (e.g., comm) we were
directly using it assuming that the parameter is valid.  Since the
previous ERRTEST macros did not jump to fn_fail on an error, this
could result in undefined behavior if the parameter was invalid.  Now,
since we jump on errors within the macros themselves, once the check
is done, we know that the parameter values are valid.

An extra argument was added to the oputil macros to provide a name,
which can be used to generate union types.  This is needed for
generating types to be included in the RMA packet headers.  The RMA code
is also modified to use this new functionality, replacing the old
hand-coded unions.

Reviewer: goodell@

The oputil.h code is useful to more than just the collectives code now,
so it makes sense to move to the common include directory.  Precursor to
a refactor of oputil.h itself to add a third (type-name) parameter to
the type macros.

Reviewer: goodell

As of MPI 3.0, the tag argument in Intercomm_create can be ignored.  Updated
intercomm_create to use a fixed tag in the collectives tag space.
