* stefano_zampini/pcbddc-development:
PCBDDC: add wrappers for PetscStackCallBLAS
PCBDDC: Final fix for locally periodic problems
PCNNCreateCoarseMatrix: fix allocation error
PCIS: consider myself as a neighbor when classifying interface nodes
PCBDDC: Remove misuses of neighbours_set in FETI-DP code
PCBDDC: Coarse solution lives in the span of phi (not psi)
MATIS: Add IsSymmetric and IsHermitian implementations
PCBDDC: More robust method to compute local boundary nodes
PCBDDC: Add partial support for periodic problems replacing Sort with RemoveDups
PCBDDC: Add support for non-symmetric linear systems
PCBDDC: Stiffness scaling should be rebuilt in any case (just to be safe)
PCBDDC: Remove trailing blanks
PCBDDC: Consistency of CSR graph passed in postponed to PCSetUp
PCBDDC: Preliminary work to split PCBDDCCoarseSetUp in simpler pieces
PCBDDC: allow compilation without metis header
PCBDDC: Optimal allocation in PCBDDCGetPrinalVerticesLocalIdx
PCBDDC: add verbosity level to graph view
PCBDDC: change boolean debug flag to integer -pc_bddc_check_level
PCBDDC: Workaround for BAIJ local matrices: convert to AIJ for coarse matrix
PCIS: Use PETSC_COMM_SELF instead of MPI_COMM_SELF
PCBDDC: many changes
ISG2LMapApply: fix __FUNCT__ and invalid access before globals are set up

PCBJacobi: call KSPSetFromOptions(subksp) when PCSetUp was called first
Prior to this patch, -mg_coarse_sub_pc_ options were never parsed when
using PCGAMG, which changes the coarse solver and calls

PCSetUp_BJacobi_Singleblock so that PCBJacobiGetSubKSP is available.

PCGAMG: set bjacobi->same_local_solves=TRUE to clean coarse grid viewing
When bjacobi->same_local_solves=FALSE, PCView_BJacobi views each
subdomain solver separately. (That output is currently jumb
PCGAMG: set bjacobi->same_local_solves=TRUE to clean coarse grid viewing
When bjacobi->same_local_solves=FALSE, PCView_BJacobi views each
subdomain solver separately. (That output is currently jumbled because
singleton viewers does not produce synchronized output, but O(P) data in
a -ksp_view is still not acceptable.) GAMG configures all local solves
identically (though all but one process will have zero entries) but in
doing so, it trips bjacobi->same_local_solves=FALSE. This commit is a
temporary fix until PCView_BJacobi is fixed to recognize this situation
in a more general setting.
