lib, bgpd, ospf6d, ospfd, pimd: Allow finish to cleanup a bit more
When calling route_map_finish, every place that we do we must
first set the deletion event to NULL, or we will create an infinite
loop, if we are using the delayed route-map application code.
As such we might as well just make the route_map_finish code
do this work, as that there is really no viable alternative here
and route_map_finish should only be called on shutdown.
This fixes an infinite loop in zebra on shutdown when there
are route-maps.

isisd: don't infer spftree from address family
Instead of using the address family to determine which spftree structure
should be used, specify it explicitly. With the advent of ipv6 dst-src

isisd: fix isis_route_merge_verify logic
This addresses two issues for L1L2 operation:
a) If an L1 route has ROUTE_ACTIVE unset and an L2 route for the same
destination has ROUTE_ACTIVE set, isisd would still put the L1 route
into the merged table. This causes the route for the destination to
get uninstalled from zebra until the next SPF run, which is incorrect.
To fix this, look at the ROUTE_ACTIVE flag and allow L2 routes to win
against L1 routes, when the L1 has ROUTE_ACTIVE unset.
b) If an L1 route wins against an existing L2 route, the ZEBRA_SYNCED
flag would remain on the L2 route. This leads to the problem that when
the L1 route disappears again, the L2 doesn't get reinstalled, since
isisd assumes it's already in the RIB because ZEBRA_SYNCED is set.
Solve this by clearing ZEBRA_SYNCED on L2 routes, if they lose against
an L1 route.

tools/frr: make frr reload error message clearer on missing frr-reload.py
Only frr-reload.py pulls in a python depenedency for frr, we can
reduce the size of the base frr package by a lot if we separate
out frr-pythontools. When we do this, we get a somewhat cryptic
error message when frr-reload.py is missing on frr reload.
Here, we pull the error message from frr-reload script, which is
much clearer.
Testing done:
frr reload both with and without the frr-reload.py script, see
the frr-reload message when missing and it runs frr-reload.py when
not missing.
