lib, zebra: move "struct vrf" to be a lib module
Previously "struct vrf" is defined locally in zebra. Now it is moved
to be a lib module.
This is the first step to support multi-VRF in quagga. The
implementation is splitted into small patches for the purpose of
easy review.
* lib:
"struct vrf" with basic members is defined in vrf.c. The member
"void *info" is for user data.
Some basic functions are defined in vrf.c for adding/deleting/
looking up a VRF, scanning the VRF table and initializing the
VRF module.
The type "vrf_id_t" is defined specificly for VRF ID.
* zebra:
The previous "struct vrf" is re-defined as "struct zebra_vrf";
and previous "vrf" variables are renamed to "zvrf".
The previous "struct vrf" related functions are removed from
zbera_rib.c. New functions are defined to maintain the new
"struct zebra_vrf".
The names vrf_xxx are reserved for the functions in VRF module.
So:
- the previous vrf_table() are renamed to zebra_vrf_table();
- the previous vrf_static_table() are renamed to
zebra_vrf_static_table().
The main logic is not changed.
BTW: Add a statement to zebra_snmp.c telling that the SNMP is
running only for the MIBs in the default VRF.
