    log: rename grl_log_init() to grl_log_configure()
    
    You can configure one or several log domains at run time with this API,
    so it's not an initialization per se, it's closer to a configuration
    string one gives to the log system.
    
    Along with the renaming, properly document the format of the string used
    to configure log domains.
