shared/utmp-wtmp: add parameter for origin tty and callback userdata

Instead of looking up the tty from STDIN, let utmp_wall() take an argument
to specify an origin tty for the wall message. Only if that argument is
NULL do the STDIN lookup.

Also add an void *userdata argument that is handed back to the callback
function.
