- need VecResetArray otherwise the CPU array placed will never be updated

STYLE: make PetscWrappedVector constructor explicit, use default constructor

- compile into FOAM_USER_LIBBIN for consistency with other
  modules

- normally not defined, but can be used to define an alternative
  installation location. More refinements in the future, pending
  changes in OpenFOAM.

ENH: added prefix to ksp and mat options; added options subdict for setting directly petsc options in the db

- identical under the hood, but the former is more OpenFOAM-like
