Added MatFactorGetSolverPackage(), also properly printed with -mat_view_info and -ksp_view

pass MatFactorInfo as const into factorization routines, they shouldn't be changing it.

commit after merge; lots of GU conflicts needed to be resolved, why? I don't know, most looked
like they could be done automatically

1) The first argument to MatXXXFactorSymbolic/Numeric() is now the factored matrix
2) The assigment of the MatXXXFactorNumeric ops pointer is now done in the symbolic factorization
the assigment of the MatSolve pointer is now done in the numeric factorization
(This is because only then do you know the right pointer that should be used)

fixed some memory bleeding
changed PetscMap in Vec and Mat to be an allocated shared
structure with referencing counting. Shared by Vecs obtained with
VecDuplicate() and MatGetVecs()
