Fix selectservers().

See Redmine #5458. Thanks to Bob Ingersoll for spotting it.
Add acceptance test for selectservers().
TryConnect() should return error when select() times out.
Logging in milliseconds is ugly.
Fix socket descriptor leak.
Acceptance test for selectservers() now checks failures as well as successes.

Unfortunately some requests may timeout, which means that the test will
take 30s to complete. In the future we should enable parallel test
harness to avoid waiting.
Selectservers() now logs INFO in case of timeout.
Beautify message.
Use dcs_passif_expected() to check and report all classes are set.
Change timeout so that acceptance test takes only 5 seconds instead of 30.

Does not work for now, should work after redmine #5497 gets fixed.

Leak-fix in FnCallRegExtract().
Report repaired compliance for promise types that use methods.

Services promises call VerifyMethod and would never be reported as
repaired, as VerifyMethod filters that result out (the promise inside
the method is still reported as repaired). Instead, filter the
compliance in the existing helper function that is called only by the
evaluator.
