From Ian Hinder:

Before this patch, CactusNumerical/Periodic assumes that the symmetry
boundary widths are the same as the number of ghost zones.  In newer
version of Carpet, the number of ghost zones can be different on
different refinement levels, and the number of ghost zones is no
longer available when the symmetry BCs are registered.  This patch
makes the Periodic thorn get the boundary widths from CoordBase
instead, in the same way that the other symmetry thorns do already.
This introduces a new dependency on CoordBase.
