X11: Add xauthority parameter

Browse source 
Add an xauthority parameter and use it in the startup script.

Apparently on some systems the X authentication cookie is not stored in
~/.Xauthority but in some dynamic location pointed to by the XAUTHORITY
environment variable. The environment variable therefore needs to be set
in the PulseAudio daemon environment in order to have access to the X
server from the PulseAudio daemon, but the variable is not necessarily
set when starting PulseAudio. For example, systemd starts PulseAudio
outside the X session. The start-pulseaudio-x11 script is run in the
X session, so it has the environment variable available, and can pass it
to the X modules, which then can set the variable in the daemon
environment.
