Subject: [PATCH] Xnest: drop support for "full regeneration"

This is (rarely used) special mode where, at server regeneration
(when last client exited), Xnest is additionally terminating and
restarting it's upstream connection, thus also recreating it's
main window, etc.

That mode is only meant for special debug scenarios, not suited for
practical use. And the same can be achieved by just terminating the
whole Xnest process (-terminate cmdline arg) and restrting it.
