[PATCH 7/9] vnc: force initial resize message

[Gerd Hoffmann]

The vnc server should send desktop resize notifications unconditionally
on a new client connect, for feature negotiation reasons.  Add a bool
flag to vnc_desktop_resize() to force sending the message even in case
there is no size change.
