That matches previous behavior of stop, so we need at least
temporarily to keep that as default.

Runtest should fail when stop command failed

Check for proper BIRD shutdown, handle stuck process or crash
during shutdown. Some changes done by commiter.

Netlab ignored most errors during stop. Check them and either stop
immediately (in default mode) or continue and report error in the
return value (in force mode). Add option -f to stop command to enable
force mode.

bird-tools/netlab/cf-babel-base/bird_m*:
+ babel protocols now have option 'rxcost' with specific value
+ horizontal links - 100,
+ vertical links - 110 (m1-m2), 120 (m7-m8),
+ net1 - 150 (m3), 152 (m4), 154 (m5), 156 (m6).

With newer kernel/iproute, the output of 'ip route' on ECMP routes is
slightly different. The patch filter-out that as a temporary workaround.

Each test case contains:
+ Bird config files,
+ Netlab config file,
+ Python test suite.

VRF tables contain both regular and local routes, with older
kernels there are these routes:

  ff00::/8 dev eth0 metric 256 pref medium

while with newer ones there are:

  multicast ff00::/8 dev eth0 proto kernel metric 256 pref medium

Extend regex to ignore also routes from newer kernels.

As they are now stable.

As they are now stable.

Also fix pattern in cf-ospf-custom and some missing imports

+ function 'test_logs' allows some types of messages (DBG, TRACE, INFO),
  but the rest of the log messages should rase exceptions

+ function 'check_expected_logs_timeout' periodically calls function
  'check_expected_logs' which watches log messages every second

- functions 'modify_command', 'save_stdout', 'get_attributes_from_output',
  'check_running_protocols' and 'check_protocol_state' were removed

There are several nondeterministic aspects affecting the order of items
in output of show route command. Link local addresses affect order of
next hops, order of convergence affects order of routes, and hash
function details affects order of nets. We sort it (hierarchically on
multiple levels) to keep it stable.
