logging: color the log level
When log_set_use_color() is enabled, color the log level string according to
the log level. The log line before and after the log level is printed in the
category's color.
ERROR and FATAL are red, NOTICE is yellow, INFO is green and DEBUG is blue.
The default behavior remains unchanged.
