lib: prepare table code for reuse by bgp_table
* lib/table.[ch] - Add a macro (ROUTE_NODE_FIELDS) that expands to all the fields of a route_node structure. - Add the route_table_delegate_t structure, a function vector which allows clients to customize the behavior of one or more tables. The delegate currently contains the 'create_node' and 'destroy_node' functions, and hence enables a table to use an alternative node structure. The alternative node is expected to embed the fields of a route_node using ROUTE_NODE_FIELDS. - Add route_table_init_with_delegate() to create a new table with a given delegate. - Make route_table_init() a thin wrapper around route_table_init_with_delegate(). The delegate it passes in simply creates/destroys route_node structures as before. - Add a user data pointer (info) to the route_table structure. This can be used by a client to keep per-table state.
