BUG: Fixes bug in plicRDF interface reconstruction across cyclic boundaries (fixes #3279)

Description:
The plicRDF interface reconstruction scheme calculates a reconstructed distance
function (RDF) in all interface cells and their point neighbours.
In point neighbours to interface cells, the RDF is calculated as a weighted
average of the distances to all adjacent interface cell centres with the weight
being the inverse distance to the cell centre.
By using the zoneDistribute class written by Henning Scheufler, the required
stencil data is communicated efficiently for stencil cells living on different
sides of one or more processor patches.
Some of the data required for the RDF reconstruction are cell centre and
interface centre positions. When a stencil extends across a cyclic patch these
positions have so far not been properly transformed in OpenFOAM. This issue is
fixed by the current contribution.
The fix is done by modifying the zoneDistribute class to hold the required
information about zone cells ad...
