Description
Context
The rewriting of mpp initialization has theoretically allowed some flexibility in defining different mpp layouts over each AGRIF grid. This includes the removal of land processors over parent and child grids.
Analysis
Boundary conditions in an AGRIF zoom are set by detecting if the processor domain includes the global domain edges. This is done by using nbondi/nbondj integers that define the type of east/west/north/south neighbors. Doing so potentially marks a local domain close to a land processor domain as a "boundary domain". Hence, AGRIF will attempt to set boundary conditions in that case. In some circonstances, this updates ocean points that should't be updated.
Fix
The use of nbondi/nbondj has been suppressed in the last version (trunk), the reasoning being done on global indexes. In earlier NEMO 4.0 versions, we should define once for all (in mppini) logicals to detect if a local domain lays on one of global domain edges.

Successfully tested mpp reproducibility in an ARCTIC zoom with lots of land subdomains.
