add 'xdg-seat' config setting for naming a seat

If specified, this setting does two things:
  * causes the "-seat <seatname>" arguments to be passed to X
  * overrides the default value of the pam_systemd XDG_SEAT variable
    ("<seatname>" instead of "seat0")

This is required for multiseat setups, as documeted at:
http://www.freedesktop.org/wiki/Software/systemd/writing-display-managers/

let 'xserver-vt=0' indicate that the user wants X to share VTs

If the user specifies 'xserver-vt=0' for a seat, then:
  * VT switching will not be performed for the Seat
  * the "vtXX" argument will not be passed to X
  * the "-sharevts" argument will be passed to X
  * XDG_VTNR will be left unset

This is required for multiseat setups.

add 'xserver-vt' config setting for forcing a Seat's VT number

This makes it possible to run multiple X servers on the same VT (using
the Xorg -sharevts option), which is required for multiseat setups.

new seat_has_property() function

This function will be used to see if the user specified a VT number
for the X seat.

1762. By Richard Hansen on 2013-08-04

log the values of the XDG_SEAT and XDG_VTNR variables

This makes it easier to debug multiseat setups.

delay setting Session pid to 0 (for logging)

The Session pid is currently used in Session log messages. Delay
setting it to 0 so that more log messages have a meaningful prefix (to
make it possible to correlate them with other log messages).

1760. By Richard Hansen on 2013-08-04

add session PID to Session (including Greeter) log messages

This makes it easier to debug multiseat setups.

1759. By Richard Hansen on 2013-08-04

have Session implement the Logger interface

This is a step toward logging the session PID in each Session
log message, which will make it easier to debug multiseat setups.

The PID is set to 0 when the Session process terminates, so it is not
possible to follow a Session's complete lifetime in the logs. But
it's better than nothing.

A future commit could easily change this to log some other identifier,
such as the associated Display or Seat name, or the PID before the
process terminated.

1758. By Richard Hansen on 2013-08-04

add display server name to DisplayServer log messages

This makes it easier to debug multiseat setups.

1757. By Richard Hansen on 2013-08-04

have DisplayServer implement the Logger interface

This is a step toward logging the display server name in each
DisplayServer log message, which will make it easier to debug
multiseat setups.
