veccuda: add VecCUDA((Re)Place/Reset)Array
Allow to (re)place the GPU array on a vector in the same way it is
done with the host memory array.
Like VecPlaceArray(), VecCUDAPlaceArray() uses Vec->unp
veccuda: add VecCUDA((Re)Place/Reset)Array
Allow to (re)place the GPU array on a vector in the same way it is
done with the host memory array.
Like VecPlaceArray(), VecCUDAPlaceArray() uses Vec->unplacedarray.
It prevents both functions to be used on the same vector at the same
time.

PetscSFBasic: fix usage of MPI_Reduce_local
If we couldn't use one of the predefined ops, then the user must specify
an op that operates on the whole datatype passed to
PetscSFReduceBegin()/PetscSFR
PetscSFBasic: fix usage of MPI_Reduce_local
If we couldn't use one of the predefined ops, then the user must specify
an op that operates on the whole datatype passed to
PetscSFReduceBegin()/PetscSFReduceEnd(). In this setting, a block size
(link->bs) that is not equal to 1 is sometimes calculated, because it
may be determined that the datatype is in fact a contiguously packed set
of e.g., PetscInt. That block size must be ignored in this setting,
because (link->bs * typesize) is not the data stride, typesize is.
