MATMUMPS: do not report error if size is 0

MUMPS does not support 0 sized problems, these errors are benign for PETSc since the solver will never be run

Fix error checking in DMDA for periodic cases where it cannot handle periodic boundary conditions

Also add error checking to MatFDColoring() to check for bad coloring input.

Also fix bug where call

Fix error checking in DMDA for periodic cases where it cannot handle periodic boundary conditions

Also add error checking to MatFDColoring() to check for bad coloring input.

Also fix bug where call to ISColoringGetIS() where the is already exists and the caller requests PETSC_OWN_POINTER

Docs: fix typos and extra characters

Kokkos: try to always have an execution space argument

Config: get rid of PETSC_HAVE_MPICH_NUMVERSION and use petscpkg_version.h

Mat: fix -Wmissing-field-initializers

This requires some changes to user FORTRAN code

Pass PETSC_NULL_XXX_ARRAY when passing a NULL as an argument that is expecting an array
Pass PETSC_NULL_ENUM when argument returns an enum instead of

This requires some changes to user FORTRAN code

Pass PETSC_NULL_XXX_ARRAY when passing a NULL as an argument that is expecting an array
Pass PETSC_NULL_ENUM when argument returns an enum instead of PETSC_NULL_INTEGER
Pass arrays (and not scalar values) when the argument is expecting an array; this means replace, for example, the argument v with [v]
Use PetscObjectIsNull(obj) to check if the object is NULL, instead of obj == PETSC_NULL_XXX

The compiler will now automatically prevent you from using the wrong argument type for the first three bullets above
This will also require an update sowing with the new sowing branch this MR is using.
