This patch introduces two command-line options for Xephyr:
* -host-display: set Xephyr DISPLAY environment variable
to host X server display number
* -host-auth: set Xephyr XAUTHORITY environment variable
to host X server authorization file path
These options are particularly useful when Xephyr is launched
directly from display manager, because DISPLAY and/or XAUTHORITY
environment variables may not be set when it's launched.
