Enhance support for multi-patch simulations

Carpet:

Ensure that at most one of GetDomainSpecificatio or
MultiPatch_GetDomainSpecification is defined.

Allow the boundary case of having zero regions on a refinement level.

CarpetLib:

Allow the boundary case of having zero components on a patch, if there
are still more than zero components overall.

CarpetIOASCII:

Loop over the components using explicit light-weight for loops instead of
Carpet's looping macros.  This is faster, since less state information
needs to be updated.

Correct an inconsistency in converting between integer indices and
coordinates in multi-patch simulations.

CarpetRegrid2:

Take multi-patch systems into account.
