lib/zserv: introduce address-family independent ZAPI message types
As noticed in 657cde1, the zapi_ipv[4|6]_route functions are broken in
many ways and that's the reason that many client daemons (e.g. ospfd,
isisd) need to send handcrafted messages to zebra.
The zapi_route() function introduced by Donald solves the problem
by providing a consistent way to send ipv4/ipv6 routes to zebra with
nexthops of any type, in all possible combinations including IPv4 routes
with IPv6 nexthops (for BGP unnumbered routes).
This patch goes a bit further and creates two new address-family
independent ZAPI message types that the client daemons can
use to advertise route information to zebra: ZEBRA_ROUTE_ADD and
ZEBRA_ROUTE_DELETE. The big advantage of having address-family independent
messages is that it allows us to remove a lot of duplicate code in zebra
and in the client daemons.
This patch also introduces the zapi_route_decode() function. It will be
used by zebra to decode route messages sent by the client daemons using
zclient_route_send(), which calls zapi_route_encode().
Later on we'll use this same pair of encode/decode functions to
send/receive redistributed routes from zebra to the client daemons,
taking the idea of removing code duplication to the next level.
