Should a call like xtl_syslog_change_facility() given out directly to 
the library users. this call can be wrapped with in a more generic call 
like
xtl_cahnge_log_place(struct xentool_logger , void *new_place);

In stdiostream implementation this can be caste to a stream and in 
syslogger implementation this can be cast as a  facility.
If some logger doesn't want to implement that we can have empty 
implementation

Well may be it should not be a hard and fast rule, but more of a best 
practice scenario then.
