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.

And update test data

Because 'assert 1' does not end a test, the old code executed each test
60 times, even if it successed in the first iteration.

Add 'table' argument to more functions to make it work.
Rename 'ip' argument to 'family', to be consistent with ip tools doc.
Switch default of 'loc' argument to be more meaningful.
Replace "temp" constant with existing cf.tempdir.
Move 'table' keyword of get_stdout_bird from callee to caller.
Remove 'pref' from ip-route output, as it is reported by some versions of ip tools.

mh-bird_tables: stripping function was changed (regex pattern now does not take into account the end of the square brackets)
