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.

1. Move the new extension FT routines into the src/mpi/comm directory
instead of the separate src/mpix directory, since it's clearly using
the MPI internals.

2. Move the MPIX_mutex functionality to mpi.h.in instead of a separate
mpix.h.  This will allow us to use device-specific mpix_foo.h
functionality that the user can use to buy-in to device-specific
extensions.

3. Move the ARMCI and Mutex functionality to src/armci and src/mutex
directories respectively.

This is a workaround to allow "negative" target displacements (i.e. target
addresses which are negative when interpreted as signed integers) in dynamic
windows.

This patch adds support for the new MPI-3 compare-and-swap routine.  The
implementation embeds the data into the packet header to reduce the number of
messages.

Added the missing disp_unit argument (was added in a later revision of the MPI
3.0 spec) and fixed a bug in base pointer calculations when processes pass a
size of 0.  Added a test case to test MPI-2 ops on shared memory windows.

[svn-r10135] Partial fixes for broken attribute handling, including FIXMEs that must still be addressed

AFAIK we have not deleted or otherwise incompatibly altered any of the
interfaces that we expose.  However, several new APIs and a few new
constants have been added, so we need to bump the "current" field while
still supporting the previous interface.  Hence, from "6:1:0" to
"7:0:1".

Libtool handles the ar flags selection for us, so putting the ar flags
inside of the $AR variable led to "ar cr cr BLAH".  The tflops configure
code is mostly harmless, but contained a similar AR assignment bug and
the platform is *long* gone.

Partial fix for tt#1639.

Also error out at configure time if no module outdir flag can be

It's not portable to Solaris (and probably elsewhere).  All of this should
be moot soon, since the PGCC depcomp fix has been accepted upstream
into automake and should be released soon-ish.

This adds the win_fns table to ch3, which allows the channel to override the
default implementation of window creation routines provided by ch3.  This also
pushes the implementation of shared memory windows down into Nemesis, includes
window functions for sock, and contains multiple improvements to the window
creation functions code.

Reviewer: buntinas

Also drop an unnecessary "$(top_builddir)" that seemed to be confusing
the FreeBSD make program for some reason.

The default nonblocking implementations use the naive "as-if" code from
the draft MPI-3 standard.  No attempt is made to optimize the
communication patterns at this time.

The default blocking implementations simply call the corresponding
nonblocking versions.  NBC overheads are unlikely to be too large for
most neighborhood collective use cases.  If this assertion turns out to
be false at some point then we can revisit this implementation choice.

Specifically for:
* MPI_Cart_shift

* MPI_Dist_graph_neighbors
* MPI_Graph_neighbors_count
* MPI_Graph_neighbors

This is a precursor to some of the neighborhood collectives
implementation work.

These annotations allow the compiler to perform type checking between
the C language type of a buffer and the MPI_Datatype specified by the
user.

This new code relies on experimental features currently under
consideration for addition to Clang:
