Link against GIO_LIBS explicitly

Clamp cursor hot-pixel to be within cursor region

Some broken VNC servers send hot-pixel outside bounds of the
cursor. We could disconnect and report an error, but it is
more user friendly to just clamp the hot pixel coords

Add preconditions to VncDisplay public methods

This should catch invalid arguments being passed to these. This required
moving the VncDisplayPrivate *priv = display->priv; assignment as the
VNC_IS_DISPLAY(display) check is also a NULL check which we want to
happen before dereferencing it.

Avoid crash if attempt to connect to an invalid host or port

If vnc_display_open_host() is called with a NULL port or host,
vnc_connection_open_host_internal() will eventually crash.
This commits adds runtime checks to return early with
g_return_val_if_fail() when this happens rather than
crashing
