lib/oelite: Add new oelite.log module
lib/oelite: Add new oelite.log module

First step towards migrating to use the standard logging module API
for debug, info, warning and error messages.

Python code should call "oelite.log.get_logger()" and use the returned
Logger object for posting such messages. Example:

    import oelite.log
    log = oelite.log.get_logger()
    log.debug("Hello world")
