Levenberg-Marquardt optimization using BRGN.

Adds diag(J^T J) as a regularizer to BRGN (called "lm"). With this
regularizer, BRGN is equivalent to a Levenberg-Marquardt algorithm.

Most external factorization packages do not use the ordering provided by PETSc, therefor only provide it when needed.

Adds MatOrderingType external to indicate not to generate an ordering and use what the package needs
Now -pc_view will not print the wrong PETSc ordering when the ordering is done externally

Saves some memory and compute time.
