Fix name MatSolverPackage since it is better to be consistent and use the terminology Type.

Added F90 interfaces for several PetscObjectXXX() operations; Add various F90 support for Mat operations

MatCreateSchurComplement is missing a custom wrapper with
CHKFORTRANNULLOBJECT, so I can't provide a PETSC_NULL_MAT for the
optional A22 block, where previously I could use PETSC_NULL_OBJECT. As
a workaround it seems I can provide it with a tMat(0) argument

* PetscObjectReference also does not have a wrapper. Calling it with
the %v attribute of the derived type seems to work however.

* Previously we had the following calling sequence:

call MatGetNullSpace(mat, nullsp, ierr)
if (ierr==0 .and. nullsp/=PETSC_NULL_OBJECT) then
call MatNullSpaceRemove(nullsp, b, ierr)
end if

Now there doesn't seem to be a PETSC_NULL_MATNULLSPACE and even if
there were, MatGetNullSpace isn't wrapped to return it.

* there is also no PETSC_NULL_RANDOM so no way to leave out the Random
object in VecSetRandom()

* not really important, but MatGetOwnerShip no longer works with
PETSC_NULL_INTEGER as advertized.
