Updated the fetch_and_op implementation to have two data transfer paths; one
where data can be embedded in the packet header and one where it is sent
separately.  With this change, the header size is back to 40 bytes.

Reviewer: buntinas

Updated the fetch_and_op test to test against multiple different datatypes.
Also updated the build system to build binaries for each datatype and run them
during testing.

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.

Reviewer: balaji

Added builtin op implementations for RMA-only ops.  MPI_REPLACE was not defined
in the op_table prior to this commit.  Also includes an alternate
implementation of the linked list test that uses fetch-and-op with these
operations to enable the use of shared locks.

Reviewer: goodell

Adds implementation of atomic fetch-and-op operation and several test cases.
