Sanitize kernel daemon signal handling and process naming.

Add a name argument to daemonize() (va_arg) to avoid all the
kernel threads having to duplicate the name setting over and
over again.

Make daemonize() disable all signals by default, and add a
"allow_signal()" function to let daemons say they explicitly
want to support a signal.

Make flush_signal() take the signal lock, so that callers do
not need to.
