Updating the BuildSystem hash for MOAB.py.

Update configuration to download MOAB v4.9.2 if requested

Adding MOAB to depend on metis/zoltan if they have been configured with PETSc

Updating download/build configuration for MOAB hash + tarball to point to v4.9.1

Configure: Also look for M4

configure: disable visibility option for static build - as its useful only for a shared/dylib build

Thanks-to: Jed Brown <jed@jedbrown.org>

This fixes cxx example warnings with arch-osx-xsdk-opt build of type:

ld: warning: direct access in function 'Teuchos::MpiComm<int>::setupMembersFromComm()' from file 'arch-osx-xsdk-opt/tests/src/sys/examples/tutorials/ex13.o' to global weak symbol 'Teuchos::MpiComm<int>::tagCounter_' from file '/Users/petsc/petsc.clone-4/arch-osx-xsdk-opt/lib/libteuchoscomm.a(Teuchos_TimeMonitor.cpp.o)' means the weak symbol cannot be overridden at runtime. This was likely caused by different translation units being compiled with different visibility settings.

Merge branch 'tisaac/feature-plex-tests-new'

This merge changes PetscSpace and PetscQuadrature to have a number of
components, so that vector-valued functionals can be defined for
non-Lagrange finite elements. Along the way, this branch also converts
the regression tests related to DMPlex that were in config/builder.py to
the new test harness, and makes lots of changes necessary for them to
be portable tests.

PetscMath: check for math functions by function pointer resolvability

I had previously tried to solve the issue of hidden symbols in math
libraries being misused in c89. Trying to set a pointer to the
functio will fail if the symbol is hidden, so this is a better
solution. I have applied it to other c99 math functions (erf, tgamma)
as well.
