Wrote a little guide for cross-compiling FRR, gleaned from notes I took
while compiling for a RPi 3B+ on a Gentoo x86_64 system.
Care was taken to keep this documentation as generic as possible so
these steps could be applied to any cross-compile targeting a supported
architecture.

gcc fucks up global variables with section attributes when they're used
in templated C++ code. The template instantiation "magic" kinda breaks
down (it's implemented through COMDAT in the linker, which clashes with
the section attribute.)
The workaround provides full runtime functionality, but the xref
extraction tool (xrelfo.py) won't work on C++ code compiled by GCC.
FWIW, clang gets this right.

This new dynamic module makes pathd behave as a PCC for dynamic candidate path
using the external library pcpelib https://github.com/volta-networks/pceplib .
The candidate paths defined as dynamic will trigger computation requests to the
configured PCE, and the PCE response will be used to update the policy.
It supports multiple PCE. The one with smaller precedence will be elected
as the master PCE, and only if the connection repeatedly fails, the PCC will
switch to another PCE.
Example of configuration:
segment-routing
traffic-eng
pcep
pce-config CONF
source-address ip 10.10.10.10
sr-draft07
!
pce PCE1
config CONF
address ip 1.1.1.1
!
pce PCE2
config CONF
address ip 2.2.2.2

peer PCE2 precedence 20

This new daemon manages Segment-Routing Traffic-Engineering
(SR-TE) Policies and installs them into zebra. It provides
the usual yang support and vtysh commands to define or change
SR-TE Policies.
In a nutshell SR-TE Policies provide the possibility to steer
traffic through a (possibly dynamic) list of Segment Routing
segments to the endpoint of the policy. This list of segments
is part of a Candidate Path which again belongs to the SR-TE
Policy. SR-TE Policies are uniquely identified by their color
and endpoint. The color can be used to e.g. match BGP
communities on incoming traffic.
There can be multiple Candidate Paths for a single
policy, the active Candidate Path is chosen according to
certain conditions of which the most important is its
preference. Candidate Paths can be explicit (fixed list of
segments) or dynamic (list of segment comes from e.g. PCEP, see
below).
Configuration example:
segment-routing
traffic-eng
segment-list SL
index 10 mpls label 1111
index 20 mpls label 2222
!
policy color 4 endpoint 10.10.10.4
name POL4
binding-sid 104
candidate-path preference 100 name exp explicit segment-list SL
candidate-path preference 200 name dyn dynamic
!

There is an important connection between dynamic Candidate
Paths and the overall topic of Path Computation. Later on for
pathd a dynamic module will be introduced that is capable
of communicating via the PCEP protocol with a PCE (Path
Computation Element) which again is capable of calculating
paths according to its local TED (Traffic Engineering Database).
This dynamic module will be able to inject the mentioned
dynamic Candidate Paths into pathd based on calculated paths
from a PCE.

It's time to say good bye to libyang 0.16.105. The recently
released libyang 1.0.184 includes numerous bug fixes and performance
improvements that we need.
Despite the major version bump from 0.x to 1.x, the libyang API is
the same except for a single backward-incompatible change in the
user types interface (which we're currently not using). Hence no
code changes were necessary to adapt FRR to libyang 1.x.
This commit also reintroduces some leafrefs that needed to be
removed from our YANG modules due to a bug that was present on
libyang 0.16.105.
