Merge branch 'master' into tisaac/dmforest

If we're going to start developing on this again, the recent changes to the
location of configuration files will make it annoying to switch to and from
this branch. Matt's and my fixes in DMPlex will also be relevant.

* master: (1557 commits)
MatLoad_MPIDense() always allocated array space even if it was previously provided
Clarified lumping options for PCFieldSplitSchurPreType SELFP.
fixed up PetscInfo in GAMG
TSErrorWeightedNorm[2|Infinity]: API changes
MatLoad_SeqDense() always allocated new space for the data even if the user already provided it
Fixed DMCompositeGetAccessArray() to support readonly vectors
Fix obviously-wrong aspects of documentation on SNESVINEWTONRSLS and SNESVINEWTONSSLS.
fixed example to compile - demonstrates a bug
var name 'len' was F90 key word
For user provided Jacobian functions they should always assembly into the second matrix, the one from which the preconditioner is built because the first may be used as matrix-free with -snes_mf_operator
Suggest --with-64-bit-indices if users mistakenly use --with-64bit-indices
Fix configure logging of integer size.
missing underscore in #define of vecgetarrayread translation of fortran stub for VECGETARRAYREAD
updated test output files to reflect differences introduced previously in PCView output
-ksp_type preonly does not support -ksp_monitor_short so remove from test line to prevent extranious warning output
missing CHKERRQ; and ugly double declaration of ierr
Plex ex3: For want of a semicolon, the kingdom was lost
MatSetValuesMPISBAIJ will now print correct global indices when error generated due to new nonzero location
completed basic use of MatSetValuesBlocked_SeqBAIJ_Inlined() by MatSetValuesBlocked_MPIBAIJ() to allow proper global indices being printed when error generated by new nonzero locations.
Added inline version of MatSetValuesBlocked_SeqBAIJ() to be used by MatSetValuesBlocked_MPIBAIJ() to print error message for nonzero block with global indices

* knepley/feature-harmonic-advection: (86 commits)
SNES: Some docs for NASM
TS: Added view for MIMEX
Plex: Silence compiler warnings
Builder: Check for missing numProcs was wrong
PetscFE: Turn off Fortran binding for PetscFECompositeGetMapping()
Plex: Fix big bug in DMPlexGetGlobalFieldOffset_Internal() - If offset is negative (dof is on another proc), then we must have end < start
Builder: Allow override of numProcs
Plex: Fix Fortran wrappers for DMLabelView() and DMPlexDistribute()
Plex+Label: Added Fortran wrapper for DMPlexCreateLabel()
Plex: Dammit, how did this not get checked in?
Plex: Refiner check for hybrid cells must use hybrid faces as well - Ghost cells in FV method are hybrid
TS: MIMEX now uses work vectors for correct grid
Plex: Adding support for FV in automatic interpolator construction - Notice that the injector cannot do the right thing until we scrap VecScatter
Plex+FEM: Using PetscFVGetDualSpace()
SNES+Doc: Added Options Database keys
PetscFV: Added PetscFVRefine() - This allows interpolation to finer grids needed for FAS
PetscFV: Added a dual space for calculating projections
DM: Better error checking in DMCoarsen()
DMDT+PetscFE: Added PetscQuadratureExpandComposite() - Replaces PetscFECompositeExpandQuadrature() - Added PetscFECompositeGetMapping()
Plex: Fixed complex type error
