From now we support multiple tables. The master_table variable is

definitely gone. Both rte_update() and rte_discard() have an additional
argument telling which table should they modify.

Also, rte_update() no longer walks the whole protocol list -- each table
has a list of all protocols connected to this table and having the
rt_notify hook set. Each protocol can also freely decide (by calling
proto_add_announce_hook) to connect to any other table, but it will
be probably used only by the table-to-table protocol.

The default debugging dumps now include all routing tables and also
all their connections.
