route-map, prefix list, and source setting support for zebrazrm.patch

The following patch:

1) adds "route-map" support to zebra
2) fixes "show route-map" (with no name arg)
3) adds "prefix-list" support zebra
4) adds a "set src" route-map command to allow specifying
     a source address for matched routes
5) adds "ip protocol" command to zebra to execute route-maps
     by protocol (or "any")
6) supports "interface", "nexthop" and "ip address" matching for
     zebra route-map's
