The master thread handler is really part of the zrouter structure.
So let's move it over to that. Eventually zserv.h will only be
used for zapi messages.

the maximum value for stalepath timer is extended to 4095 to align with
bgp restart timer value.
Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>
rfc of bgp graceful restart mechanism permits to increase the
restart timer, since its value is encoded on 12 bit.
So make available the possibility to extend it.

When we get into rib_process_result and the operation we are handling
is DPLANE_OP_ROUTE_UPDATE *and* the route entry being looked at
is a route replace, we currently have no way to decode to the old_re
and the re due to how we have stored context. As such they are the
same pointer.
As such the route replace for the same route type is causing the re
to set the installed flag and then immediately unset the installed
flag, leaving us in a state where the kernel has the route but
the rib thinks we are not installed.
Since the true old_re( the one being replaced by the update operation )
is going away( as that it zebra deletes the old one for us already )
this fix is not optimal but will get us moving forward.

Read the onlink flag from the kernel for routes and pass them
up and through to zebra so that we are consistent with what
the kernel is telling us.

If we receive a valid message from the kernel that
is either a kernel or system route, we should trust
that the route is legit and just use it.

The route entry being displayed in debugs was displaying
the originating route type as a number. While numbers
are cool, I for one am not terribly interested in
memorizing them. Modify the (type %d) to a (%s) to
just list the string type of the route.

Apparently 'f' means both OpenFabric and a Failed kernel
route installation.
Let's switch the 'f' for the failed kernel route installation
to 'r - rejected route'.

In extended-mobility case ({IP1, MAC} binding),
when a MAC moves from local to remote, binding
changes to {IP2, MAC}, local neigh (IP1) marked
as inactive in frr.
The evpn draft recommends to probe the entry once
local binding changes from local to remote.
Once the probe is set for the local neigh entry,
kernel will attempt refresh the entry via sending
unicast address resolution message, if host does not
reply, it will mark FAILED state.
For FAILED entry, kernel triggers delete neigh
request, which result in frr to remove inactive entry.
In absence of probing and aging out entry,
if MAC moves back to local with {IP3, MAC},
frr will mark both IP1 and IP3 as active and sends
type-2 update for both.
The IP1 may not be active host and still frr advertises
the route.
Ticket:CM-22864
Testing Done:
Validate the MAC mobilty in extended mobility scenario,
where local inactive entry gets removed once MAC moves
to remote state.
Once probe is set to the local entry, kernel triggers
reachability of the neigh/arp entry, since MAC moved remote,
ARP request goes to remote VTEP where host is not residing,
thus local neigh entry goes to failed state.
Frr receives neighbor delete faster and removes the entry.

two kind of rules are being set from bgp flowspec: ipset based rules,
and ip rule rules. default route rules may have a lower priority than
the other rules ( that do not support default rules). so, if an ipset
rule without fwmark is being requested, then priority is arbitrarily set
to 1. the other case, priority is set to 0.
