Other (really nice!) change I've noticed is that now we can call
{Vec|Mat}Create() and next {Vec|Mat}SetType() and it works!

However, see this.

In [1]: from petsc4py import PETSc

In [2]: x = PETSc.Vec().create()

In [3]: x.setType('seq')

In [4]: print x.getType()

None

In [5]: A = PETSc.Mat().create()

In [6]: A.setType('seqaij')

In [7]: print A.getType()

None


Internally, the "type_name" field is never set, it still is NULL (then
petsc4y returns None).
The problem is that forcing the "type_name" to be set will be really
dangerous (rmember PetscValidType macro).
Any comments?
