In GRASS 7, the value returned from the Rast_open_* functions (and
passed to other raster functions to identify a map) isn't a file
descriptor, but an index into a table of open maps.
In earlier versions, the value is both the descriptor of the open cell
file and an index into the table of open maps, so it's still necessary
to close maps with G_close_cell() or G_unopen_cell() in order to
release other resources associated with the map.
