The order of ECMP nexthops currently depends on whatever order the
pqueue code returns the vertices in, which is essentially random since
they compare as equal. While this shouldn't cause issues normally, it
is nondeterministic and causes the ldp-topo1 test to fail when the
ordering comes up different. Also, nondeterministic behaviour is not a
nice thing to have here in general.
Just sort by nexthop address; realistic numbers of ECMP nexthops should
hopefully not make this a performance issue. (Also, nexthops should be
hot in the caches here.)

The ospf6_route_get_first_nh_index function call calls
listhead which returns a (listnode *) but we are casting
it to a (struct ospf6_nexthop *) and away we go.

MD5 auth on TCP is supported for prefixes in recent versions of Linux;
add complementary support for FRR.
This is a reworked version of Donald's commit to keep library
compatibility and obviate the need for changes in daemons that don't
need to support this themselves.

libyang defaults CMAKE_BUILD_TYPE to "Debug", which disables compiler
optimizations. We should instruct our users to build libyang in the
"Release" mode so that compiler optimizations are enabled and they
can benefit from the associated performance improvements.

Move down the "circuit-type" leaf in the isisd YANG module so that
"ip[v6] router isis" will be the first commands displayed in the
running configuration.
Fixes#4028.

Split the "debug northbound" command into the following commands:
* debug northbound callbacks configuration
* debug northbound callbacks state
* debug northbound callbacks rpc
* debug northbound notifications
* debug northbound events
* debug northbound client confd
* debug northbound client sysrepo
If "debug northbound" is entered alone, all of its suboptions
are enabled.
This commit also adds code to debug state/rpc callbacks and
notifications (only configuration callbacks were logged before).
Use the debugging infrastructure from "lib/debug.h" in order to
benefit from its facilities (e.g. MT-safe debugging) and avoid
code duplication.

- Change MPLS-TE from global to per Area
- Add new mpls_te_area structure to area in replacement of global variable
isisMPLS_TE
- Move mpls-te frmo global to instance in frr-isisd.yang

This command is added to provide detailed information. It will be
useful in troubleshooting as we will be able to dump all detailed info
using a single command.
"show bgp l2vpn evpn route [detail] ...". Additional filtering
can be done by providing type of the route.
Command will display the detailed content for all rd and macs-ip as
displayed by "show bgp l2vpn evpn route rd <> mac <>" for a single
rd, mac, ip from the global bgp routing table.

Testing-Done:
When having a route recovery, because of the route installation
cycling and the next hop label check, it could happen that the PW
never gets recovered. The original code shows the intention of retrying,
but the code was missing. The fix includes the call to the timer programming
the recovery attempt.
Example for reproducing the issue:
|P1| <-> |P2| <-> |P3|
- Being P1, P2, P3 nodes, using IS-IS as IGP, and having a pseudowire
betwen P1 and P3 (P1, P2, P3 having configured LDP daemons).
- After 60 seconds, kill the IS-IS daemon in P2.
- Wait 30 seconds
- Launch again the IS-IS daemon in P2
- The bug/issue is that after P1 <-> P3 recovering connectivity sometimes
the PW is not recovered because the reason explained in the first paragraph.

The decision for Update_SPTbit(S,G, iif) includes a test
