vnc: implement shared flag handling.
VNC clients send a shared flag in the client init message. Up to now
qemu completely ignores this. This patch implements shared flag
handling. It comes with three policies: By default qemu behaves as one
would expect: Asking for a exclusive access grants exclusive access to
the client connecting. There is also a desktop sharing mode which
disallows exclusive connects (so one forgetting -shared wouldn't drop
everybody else) and a compatibility mode which mimics the traditional
(but non-conforming) qemu behavior.
