PCGAMG_Classical: Leave diagonal of the graph intact.

This was causing VecAssemblyBegin() to hang in the MIS coarsening code.

Sys: add PetscMalloc1 macro, array allocation without redundant types

The type is inferred from the pointer return type. This patch is
automated via the following script:

git grep -l 'PetscMalloc(.*sizeof' src | xargs perl -pi -e 's@PetscMalloc\(([^,;]*[^,; ]) *\* *sizeof\([^,;()]+\),@PetscMalloc1($1,@'

This commit contains an additional bug-fix in csrperm.c, fixing pointer
arity. The code was introduced in 2006, but the allocation could not
have been correct at any time. This probably means that
MatDuplicate_SeqAIJPERM has never been tested.

Added MATSEQCSRPERM support for MatDuplicate() and conversion to/from
MATSEQAIJ. Note that these changes are not quite debugged.

PCGAMG_Classical: Added Jacobi smoothing for the OptProl part

PCGAMG_Classical: Fixes for complex and 64-bit index builds in the new interp.

PCGAMG_Classical: Added PCGAMGClassicalSetType() and registration

PCGAMG_Classical: Add thresholding for the prolongator entries

PCGAMGClassical: Standard interpolation now works for scalar problems.

PCGAMG_Classical: Begin standard interpolation; match direct.

This matches the direct interpolation previously implemented as
a bug check. The next step is to add the indirect entries.
