Even though I really like the high repeat-rates, it might not be the best

Configuration handling is totally independent from kmscon_main.c so we
move it into a separate file to avoid cluttering up kmscon_main.c.
This also does some basic initialization in kmscon_conf.c which is solely
related to configuration handling and logging.
