GNU Readline 8.1 enables bracketed paste by default. This results in
newlines not ending the readline() call, which breaks the ability of
users to paste in configs to vtysh's interactive shell.
Disable bracketed paste.

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

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.

There exists a world where some people have put `end` in their
configuration. Then vtysh will command search for it and find
it and then bad things happen.

With a config that contains a large number of prefix-lists a 'show run' command
was an expensive operation:
sharpd@eva ~/frr_internal2 ((cl4.1.0))> time vtysh -c "show run" | grep ACTIVE | wc -l
32397
________________________________________________________
Executed in 14.53 secs fish external
usr time 14.45 secs 591.00 micros 14.45 secs
sys time 0.03 secs 189.00 micros 0.03 secs
sharpd@eva ~/frr_internal2 ((cl4.1.0))>
Effectively we are keeping a linked list of data to store the configuration.
When we received a new item we would look in the list to see if it already
does, by doing a string search across each element in the list.
Add to the master configuration a hash of items for O(1) lookup.
Keep the list for order so we don't mangle that up.
New time:
sharpd@eva ~/frr_internal1 (dev)> time vtysh -c "show run" | grep ACTIVE | wc -l
