PetscSF: define guard for MPI_COMBINER_NAMED

Necessary to avoid build errors with mpiuni.

strumpack: enable Regression tests

Configure: Added requireModule() to framework which only changes dependencies

update to STRUMPACK-sparse-1.0.3 to resolve its problems with complex and Mac shared libraries

fix Strumpack.py to pass in locations of packages via CMake variables instead

of cheating by passing them in through the compiler and linker flags

use shared libraries like any sane person

Update to STRUMPACK-sparse 1.0.2.
Remove openmp requirement.

Download STRUMPACK-sparse-1.0.1 iso 1.0.0.
1.0.1 fixes a memory leak and
checks the PETSc MPIAIJ input for NULL pointers.
It also disables the use of __gnu_parallel.

Add interface to STRUMPACK-sparse.

This commit adds 2 interfaces to STRUMPACK-sparse: one for
aij/seq and one for aij/mpi matrices. It also adds a script to
the buildsystem to download/compile/install STRUMPACK-sparse.

I can get everything compiled with
./configure --download-strumpack --with-cxx-dialect=C++11 \
--with-openmp --download-scalapack --download-parmetis
--download-metis --download-ptscotch
(There was an issue compiling STRUMPACK-sparse as a shared
library, so it is now always static)

I tested the new code with the src/snes/examples/tutorials/ex5.c
example:
OMP_NUM_THREADS=2 mpirun -n 2 ./ex5 -da_grid_x 100 \
-da_grid_y 100 \
-pc_type lu -pc_factor_mat_solver_package strumpack_mpi \
-ksp_monitor -mat_strumpack_mpi_matinput DISTRIBUTED \
--sp_mc64job 0 --sp_reordering_method scotch --sp_verbose

The aij/mpi solver is called 'strumpack_mpi', the aij/seq solver
is 'strumpack'. All command line options are passed to the
STRUMPACK solver, including -h, which prints out the STRUMPACK
options.

STRUMPACK-sparse has 3 interfaces:
* A sequential/nulti-threaded interface. This one is used with
aij/seq matrices by selecting the 'strumpack' solver.
* A distributed memory solver with replicated interface. This
interface has the same input on every MPI proc (entire matrix
and rhs and solution vectors). Select this for aij/mpi, with
"-pc_type lu -pc_factor_mat_solver_package strumpack_mpi -mat_strumpack_mpi_matinput GLOBAL"
* A fully distributed solver, works with the aij/mpi block-row
distributed input matrix directly. Use with:
"-pc_type lu -pc_factor_mat_solver_package strumpack_mpi -mat_strumpack_mpi_matinput DISTRIBUTED"
