small bug fixes and typos,
test cases that exercise the bjacobi preconditioner with cusp and cusparse solvers,
removal of cudaMemcpyAsync (and the cudaHostRegister/cudaHostUnregister),
and replacement of VecGetArray/VecSetArray calls in PCApply_BJacobi_Singleblock
with a new vector method VecGetLocalVector

PCBDDC: use vecduplicatevecs instead of explicit loop

update use of PetscOptionsBool() to not rely on default setting automatically

cleanup of use of PetscOptionsInt and friends including use of flag final argument

fixed documentation for PetscOptionsXXX that refered to "default value" when they really mean current value
also fixed usage of PetscOptionsEnum() with regards to current value in several calls

bjacobi: fix incorrect read access of vecs.
This breakage caused runex43_bjacobi in src/ksp/ksp/examples/tutorials
to not converge (and take forever to run in nightlybuilds)

Remove PETSC_HAVE_CUSP_SMOOTHED_AGGREGATION, use PETSC_HAVE_CUSP instead.

The smoothed aggregation preconditioner in cusp is available by default,
so there's no need to artifically split the functionality in the CUSP package.
Simplifies the build system without introducing new build issues.

PCIS; pc->pmat is longer accessible during PCISDestroy

a simple solution is to take a reference to the mapping during PCISSetUp

PCIS; ISLocalToGlobalMappingRestoreInfo requires mapping as an argument

PCBDDC: wrong mat type

MatGetVecs() and KSPGetVecs() replaced with MatCreateVecs() and KSPCreateVecs()
since they are creators not getters
