Merge branch 'barry/refactor-vecscatter-2'

Fix some remaining Register()s to call InitializePackage()

Changed VecScatterCreate() to take a communicator and return scatter as other first class PETSc objects do.

Changed VecScatterCreate() to take a communicator and return scatter as other first class PETSc objects do.
Changed old VecScatterCreate() to VecScatterCreateWithData()

Completed basic refactorization of VecScatter code, ready for new implementations to be added.

(There is still some code duplication between the VecScatter MPI1 and MPI3 code but it can be fixed at anytime without requiring changes to the VecScatter API.

Part 5 of a refactorization of VecScatter to be treated as a first class PETSc object

MATSEQAIJCUSPARSE: specialize MatMultAdd to perform MatMult

the previous MatMult implementation was buggy for compressed row storage
the previous MatMultAdd implementation was also buggy for non-com

MATSEQAIJCUSPARSE: specialize MatMultAdd to perform MatMult

the previous MatMult implementation was buggy for compressed row storage
the previous MatMultAdd implementation was also buggy for non-compressed row storage

the MatMultTranspose* operations are likely to be buggy since they appear to not cover all of the cases,
but just the special cases used in MPIAIJCUSPARSE!
