Implemented the framework for MPI_T enums, categories, performance variables.
and control variables specified in MPI3. Fix #1898, #1930.

The code should make MPICH MPI_T compliant, though not all MPICH pvars/cvars
are currently exposed through MPI_T.

The code supports multithreading up to MPI_THREAD_MULTIPLE.

MPI_Type_get_extent_x and MPI_Type_get_true_extent_x were throwing
errors when passed an uncommitted user-defined datatype. This was
incorrect. Closes #1774

ERR_NO_SUCH_FILE is a better choice, but ERR_IO is valid.

Adds to the test suite a way to include tests that are specific to
a particular implementation.  Currently includes only one for MPICH,
testing the basic features of mpi_t.  This also serves as a test of the
implementation tests themselves.

The numbering of MPI_COMBINER constants was changed when we added
MPI-2.2 support.  This patch reverts that numbering and adds the
MPI-2.2 specific combiners to the end, to maintain ABI compatibility
with older mpich releases.

An initial version of this patch was contributed by Intel.

This was changed to 1024 to give space for larger error strings.  But
this caused an ABI breakage for a number of MPICH partners.  This
patch reverts the size back the size to what we had in older mpich
releases.

xfails are primarily for our consumption, so we disable them by
default. This will result in cleaner test output for the average
user.

Also note that if the testsuite is configured in strict MPI mode,
all strict tests, regardless of xfail, will run.

continue the slow and intermittent process of adding error checking to
romio test cases

ROMIO tests were not cleanly buildig with --enable-strict, mostly due to
missing 'const' for strings.   One test uses strdup, which is
incompatible with strict ansi.

for years we've added hints by cutting and pasting.  Turn all this
dupilcated code into common hint processing funcitons.   Still need to
do this for all drivers, too

Some builtin kinds (e.g., MPI_DOUBLE_INT), can have extra padding when
a vector of them is copied.  So we need to use the extent for such
types, not just the size.  In this commit, we just simplify the
optimization to only work on BUILTIN types, which do not have this
issue.

Optimize the case where the origin and target both use basic
datatypes.  In this case, we assume that the data is aligned correctly
for the appropriate datatype and perform a direct assignment instead
of a memory copy.
