* Control.cs: Make IsRecreating internal so that the driver can
check it
- Temporarily remove the Hide when controls are removed, its
making a whole bunch of things not work because visibility isn't
getting reset elsewhere correctly
* Form.cs: Need to do a full handle recreation when the mdi
* parent
is set.
* XplatUIX11.cs: If we are recreating handles don't dispose the
HWNDs. What was happening is the handles were being recreated
in
SendWMDestroyMessages, but then flow continued on in that method
and destroyed the new handles.
