request for advice cleaning up SNES

[Lisandro Dalcin]

In de process of cleaning up SNES, I am not sure about the management
of afine (rhs) vector. So the question is:

If the user call:

SNESSolve(PETSC_NULL, x)

should any previously set (VecSetRhs) afine vector be destroyed/zeroed
or should it not be touched in any way?

BTW, I believe in the past you had and next removed
KSPSetRhs()/KSPSetSolution() . Should this approach be also followed
in SNES? IMHO, the final interface would be simpler and less
error-prone.
