Somewhere along the line core-files stopped being generated
with the running of the topotests. With this change we now
see this:

Our topotests send SIGBUS 2 seconds after a SIGTERM is
initiated. This is bad because under a heavily loaded
topotest system we may have a case where the system has
not had a chance to properly shut down the daemon.
Extend the time greatly before topotests send SIGBUS.

- Fix xterm support to work, previously it mostly didn't, not it should
in all cases (i.e., single or dist mode).
- Catch when the user tries to use various window requiring topotests
features (e.g., --cli-on-error) but isn't running under supported
system (e.g., byobu/tmux/xterm), and fail the run with an explanation.

TMUX and Screen support when running topotests inside docker. This
allows the gdb, shell and vtysh features to correctly work even when
running the tests inside docker.
Add options:
--asan-abort :: aborts the process on ASAN errors
--strace-daemons :: strace some or all daemons

The current log prints maximum wait time which is not actually correct,
because it doesn't include the command execution time. We usually have
"failed after X seconds" log with X being far longer than this maximum.
Let's print the maximum number of tries instead.

Pass the topogen 'tgen' object into the startRouterDaemons()
method. it can be used to start a debug cli immediately after
starting a daemon, and that can be handy.

When parsing the output of "ip -6 address", allow arbitrary base interface
names (the part after "@" in the interface name), not just "if0-9". Without
this, link-local addresses sometimes are attributed to the wrong interface
because we're not matching the interface name but still handle the
interface's addresses.

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.
