ifdef test on the need for a prototype declaration was using the
wrong name.  This may have been caused by a change in the name
of the CPP value without correcting the use of that name in this file.

We were disabling VA_ARGS whenever the compiler throws warnings.
However, in some cases, the compiler is throwing warnings in general
(because of bad user-specified flags) and not specifically because of
VA_ARGS.  See discussion on the discuss@mpich.org mailing list:
http://lists.mpich.org/pipermail/discuss/2014-February/002246.html



This patch works around this issue by checking the difference in the
warning flags with and without VA_ARGS.

Fixes #2047.

This test moves the sendrecv2 and sendrecv4 test from MPICH-1 to the new
MPICH tests.  It has been updated to use the MTest framework.  This test
uses the datatypes created by the dtypes.c file (also moved from
MPICH-1).

These tests involve creating a structure type with an explicit offset of
a variety of types, and then communicated with MPI_BOTTOM as the buffer
location.  Several of these tests failed in a recent update to the Dataloop
code for optimization of performance.

This patch breaks ABI compatibility between this and older versions of
MPICH, but is needed to get MPICH closer to the ABI compatibility
initiative with Intel, IBM and Cray.

This patch does not make the resultant mpicxx.h exactly the same as
what Intel MPI ships, but most of the publicly exposed virtual
functions should be in order.  The remaining functions that are
out-of-order are Reduce_scatter_block and Call_errhandler for
communicators, which are placed after the internal Clone function.

MPI_COMM_IDUP currently just asserts out when we use it in
multithreaded mode.  This is overly conservative.  MPI_COMM_IDUP works
fine in such modes unless it is executed concurrently with another
routine that also tries to allocate or free a context ID.  Removing
this assertion till we find a more appropriate way of tracking this
error.
