moved localtoglobal mapping bmapping of matrices and vectors into the PetscLayout object

Hg-commit: 9101686a27a1dc39bda221d0212c5e4e16e2b091

MatDuplicate_XXX() and MatGetVecs_XXX() now reference the previous objects PetscLayout instead of making a new one for the created objects

Hg-commit: 09acbe7f87158c1125044b0743c911c532c88a17

various MatDuplicate_XXX() that previously used PetscLayoutCopy() now use PetscLayoutReference() to share the same layout.

Changes to the Parallel GPU sparse matrix vector multiplication. It is now far more efficient due to overlapped communication and computation. To use these features, one must configure with
--with-t

Changes to the Parallel GPU sparse matrix vector multiplication. It is now far more efficient due to overlapped communication and computation. To use these features, one must configure with
--with-txpetscgpu=1 --download-txpetscgpu=no
One has 4 choices for the matrix storage format: csr, coo, dia, and ell. A kernel for the inodes (csr format only) is also supported. These are accessed with
-cusp_storage_format ell

Lastly, cusparse algorithms are now used for the upper and lower triangular solves.
