(cherry pick from commit 018a96d03f)
Create config_logger, logger and logger_read to house the log
interfaces. Add fake_logger, logd_logger and pmsg_logger to
house the write and read transports. Allows for an easier and
direct path to add new transports to the library.
SideEffects: None, logger benchmark performance unaffected
