When installing a table route into the kernel choose
RTPROT_ZEBRA as the installing/controlling protocol.
This way we can know we installed it as well as stop
the warnings about this special case of `ip import-table XX`

When we are importing/removing the table entry from table X into the
default routing table we are not properly setting the table_id
of the route entry. This is causing the route to be pushed
into the wrong internal table and to not be found for deletion.

The import table code assumes that they will only work
in the default vrf. This is ok, but we should push the
vrf_id and zvrf to be passed in instead of just using
VRF_DEFAULT.
This will allow us to fix a couple of things:
1) A bug in import where we are not creating the
route entry with the appropriate table so the imported
entry is showing up in the wrong spot.
2) In the future allow `ip import-table X` to become
vrf aware very easily.

The import-table code when looking up the table to use
for route-import was reversing the order of the table_id
and vrf_id causing us to never ever lookup a table
and we would cause the `ip|ipv6 import-table X` commands
to be just ignored.

1) If we are moving the nexthop we are tracking to
a new rn in the rib, then we know that the route
to get to that nexthop has changed. As such
we should notify the upper level.
This manifested itself because the code had a trigraph `?`
in the wrong order. Put the comparison in the right order.
2) If we are re-matching to the same rn and we call compare_state
then we need to see if our stored nexthops are the same or different.
If they are the same we should not notify. If they are different
we should notify. compare_state was only comparing the flags
on a route and since those are not necessarily the right flags
to look at( and we are well after the fact that the route has
already changed and been processed ) let's just compare
the nexthops to see if they are the same or different.

In a pim-evpn setup (say TORC11<=>TORC12) an mroute can have a mix of
PIM and IGMP joins. The vxlan termination device ipmr-lo is IGMP
joined on termination mroutes and the peerlink-rif can be pim joined
on the same mroute if the MLAG peer (TORC11) loses all its uplinks to
underlay -
root@TORC12:~# net show pim state 239.1.1.101|grep pimreg
1 * 239.1.1.101 uplink-1
pimreg(I ), ipmr-lo( J ), peerlink-3.4094( J )
root@TORC12:~#
When the uplinks come back up on TORC11 it will prune the peerlink-rif
and join the RP (say spine) via the uplinks.
TORC12 is rxing the prune and removing the if_channel
(pim_ifchannel_delete). However it is not removing the OIF from
mfcc_ttl basically leaving behind a leaked OIF in the forwarding
entry. And this is because it is deriving the owner flag from the
parent upstream entry and incorrectly concluding that all OIFs are
IGMP joined.
Thix fix flushes out both PIM and IGMP ownership when the ifchannel is
deleted.
There is a second fix in the commit and that is to set the proto mask
correctly (to STAR) for inherited OIFs. (S,G) entries can inherit the
OIF from the (*, G) entry and this decision can change when the pim/igmp
ifchannel is removed. The earlier code was setting the proto-mask
incorrectly to PIM or IGMP.

The problem was as a part ifchannel_delete the join state of the channel
was checked to avoid incorrect OIF deletion this was preventing the OIF
from being flushed. Fix is to flip the channel join-state to NOINFO before
deleting it.
