Re-enabled Xnest fix for focus in + modifier bug.

This takes the xnest way of working around this (see
5904ef2ccd "xnest: restore
xnestUpdateModifierState") and copies it to Xephyr.

* What should happen is that focus out should do as a VT switch does in

* to think of it) currently down. Then, on focus in, get the state from
* the host, and fake keypresses for everything currently down.
*
* So I'm leaving this broken for a little while. Sorry, folks.
