Merge branch 'master' into knepley/feature-composable-callbacks

* master: (151 commits)
PetscMalloc: Fix handling of zero-sized allocations
add note to DMGetLocal/GlobalVector() about intended short-time usage of the vectors.
sf: use patched openmpi tarball that has a potential fix for sf example hang
SNES problems that set VI bounds must use a VI solver since the other solvers ignore the bounds
pounders viewer did not cast PetscReal to double in printf nor use %D instead of %d
fix ts ex20adj
fix ts theta
fixed another variable declaration in the middle of a code block
example main() had PetscInt return type and argument that should be int
DMDAVTKWriteAll_VTS: Fix handling of higher-dimension coordinates
fixed example that declared variables in the middle of a function
C programs do not return PetscInt nor do they take an argument that is PetscInt, fixed example that did
You cannot declare variables in the middle of functions in PETSc.
add ierr checking to PetscOptionsBegin/End() in example
configure: add error check if user specifies PETSC_ARCH=-dbg [i.e starts with a '-']
scale norm of vector difference by norm of vector to insure it is small enough to consider the two vectors equal
missing PetscViewerDestroy() added
MatNestGetISs: use custom fortranstub to handle PETSC_NULL_OBJECT
update location of open-mx website on FAQ page
If the user sets bounds and calls a solver that does not support them, throw an error.

Merge branch 'master' into knepley/feature-viewer-partial-read

* master: (48 commits)
ViennaCL: Fixes memory leak when destructing an aijviennacl matrix.
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: Reorganized PlexPoint interface - Added DMPlexGetPointLocalField() and DMPlexGetPointGlobalField() - Now the DMPlexGetLocalOffset*_Private() functions return start and end - Uniformly use private functions
Plex: Put in explicit cast
MatSetValuesMPISBAIJ will now print correct global indices when error generated due to new nonzero location

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.

Added inline version of MatSetValuesBlocked_SeqBAIJ() to be used by MatSetValuesBlocked_MPIBAIJ() to print error message for nonzero block with global indices

When generating error new nonzero location in MatSetValues_MPIxxx() calls print the global row/column number of the offending location
Previously this printed the number inside the local sequential portion of the matrix which is confusing for users

Note that this cannot be done trivially for MatSetValuesBlocked_MPIxxx() because the insertion in the submatrix is in a seperate function that does not know about the calling function
