Comment:

 Ready for review in branches/trac176.

 Currently, python logging module supports four channels(null, file, syslog
 and stderr) and five levels (debug, info, warning, error and critical),
 more levels will be added later.

 The logging severity and file channel configurations can be reconfigured
 at runtime through bindctl. xfrout module has been updated as the first
 module to use logging framework.
