Branch 2017/dev_r8126_ROBUST08_no_ghost. Incorporation of re-written lbc routines. This introduces generic routines for: lbc_lnk, lbc_lnk_multi, lbc_nfd, mpp_bdy, mpp_lnk and mpp_nfd in .h90 files which are pre-processor included multiple times (with different arguments) to recreate equivalences to all the original variants from a much smaller code base (more than 2000 lines shorter). These changes have been SETTE tested and shown to reproduce identical results to the branch base revision. There are a few caveats: the ice cavity routine: iscplhsb.F90, needs to be rewritten to avoid sums over the overlap regions; this will be done elsewhere and has merely been disabled on this branch. The work is not yet complete for the nogather option for the north-fold. The default MPI ALLGATHER option is working but do not activate ln_nogather until further notice.
