vnc_server_cut_text_caps() is not guaranteed to be called only once.
If it called twice, we finally call notifier_list_add() twice with same
element. Which leads to loopback QLIST. So, on next
notifier_list_notify() we'll loop forever and QEMU stuck.
So, let's only register new notifier if it's not yet registered.
Note, that similar check is used in vdagent_chr_recv_caps() (before
call qemu_clipboard_peer_register()), and also before
qemu_clipboard_peer_unregister() call in vdagent_disconnect() and in
vnc_disconnect_finish().

This patch adds support for cut+paste to the qemu vnc server, which
allows the vnc client exchange clipbaord data with qemu and other peers
like the qemu vdagent implementation.
