Paul Eggleton b7d53f2ebb scripts: add scriptutils module
Add a utility module for scripts. This is intended to provide functions
only really useful before bitbake has been found (or only of particular
interest to scripts). At the moment this includes functions for setting
up a logger and for loading plugins.
