6d38d0785c 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
routing, the tree cannot be uniquely determined from the family.

26b0598f6b 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.

3dace42de9 isisd: move route_table into spftree
As isisd's route_tables are directly related to spf trees, move

c9b0e434bc isisd: add debug message if adjacency is ignored because IP is unusable
isisd verifies whether the neighboring IPv4 addresses overlap with its own
unless the interface is running in unnumbered mode. If no overlap is found
and IPv6 is also not enabled, IIHs will be ignored.

Add a debug message for this case, to avoid people wondering why adjacencies
are not coming up.

8b5f787e8e 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.

c969b2edae bgpd: Intentionally stop some timers on instance removal
When a bgp instance is stopped, with a `no router bgp..`
make sure any timers associated with the instance are stopped
as well.

This issue was discovered when a customer issued a `no router bgp`
while a maxmed timer was operative.  The max-med timer used the
`struct bgp *` as the passed in value for the thread.  The
thread eventually popped after the cleanup and attempted to use
data off in lala land and crashed
