zebra: add way to determine VRF/AFI/SAFI of table
Add some code that allows us to determine which VRF and AFI/SAFI a
given RIB table corresponds to.
* zebra/rib.h
Add rib_table_info_t structure, which contains information about
the VRF, AFI and SAFI that a table is for.
* zebra/zebra_rib.c
- Add the vrf_table_create() function, which creates a table and
sets its 'info' pointer to a newly created rib_table_info_t.
The 'info' pointer allows us to go from a route_node or a table
to the associated vrf.
- vrf_alloc(): Use vrf_create_table() to create tables.
* lib/memtypes.c
Add memory type for rib_table_info_t.
