Use LoopControl? to parallelise loops via OpenMP.
Refactor the "work horse" routines that perform the actual copy
routines. These routines are specialised for common cases that need to
execute efficiently, in particular for the cases encountered in
RotatingSymmetry?90 and RotatingSymmetry?180 when handling CCTK_REAL
variables.
Offer an additional API (Slab_MultiTransfer_Init,
Slab_MultiTransfer_Apply, Slab_MultiTransfer_Finalize) that calculates
the communication schedule only once, and then re-uses it in further
calls. This avoids some communication overhead. Remove old CVS header
comments.

MPI_Alltoallv or to use MPI_Irecv, MPI_Isend, and MPI_Wait to
communicate. The latter is not tested, but may be faster if only a
few of all processors are involved in the communication.
Disable some self tests: Allow processors who do not participate in
the communication (who specify a zero slab size) to not know the
geometry of the source and destination slabs.
