XQuartz: Integrated xpbproxy into the server.

Added a configure option called --enable-standalone-xpbproxy which is useful for deveoping xpbproxy.
The 'active' switch in preferences just disables the in-server xpbproxy (not this standalone).
(cherry picked from commit 42944936326ef8732f622db9f75b79a92980550d)
