MatShellGetScalingShifts: consolidate checks for MatShell subtypes

Add shared memory support for PCMPI using both shmget() and MPI_Win_allocate_shared()

Remove use of private() from OpenMP pragma's since Jed says they are unsafe

Thanks-to: Jed Brown

Add OpenMP directive to MatMult_SeqAIJ etc

Gives pretty good speedup on good memory-bandwidth Intel system and M2 Mac

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

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

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.
