fixed hdf5.py so that if self.libraries.compression is None the code still runs correctly
DMDA: fix bad cast of DM_DA to PetscObject
MatClique: follow DistMultiVec API changes
MatClique: remove unused variables
config cmakeboot: add C++ flags any time compiler is available
config OpenMP: check for C++ flag any time the compiler is available
replaced all left-over uses of a single PetscMalloc() to allocated multiple arrays: replaced with PetscMallocN() The only ones left are when the second array is set into the first array and one ugly usage in the MUMPS interface that cannot be easily fixed

PCIS: consider myself as a neighbor when classifying interface nodes

Local periodic nodes should be considered has interface nodes.

PCBDDC: More robust method to compute local boundary nodes

Using counter vector to infer local boundary nodes is wrong in case a
subdomain has local periodicity.

PCIS: Use PETSC_COMM_SELF instead of MPI_COMM_SELF
