Added some root layer locking in ServerWindow.cpp when accessing the layer tree. Moved HWInterface management out of DisplayDriverPainter and into Desktop. Removed all the directly hardware related functions from DisplayDriver API. They just called the same HWInterface functions. Now DisplayDriver is much cleaner and ready for being attached to a yet to be written BitmapHWInterface. Clean up of the display mode stuff in Screen and the View-/AccelerantHWInterface. Frequency is now regarded on Haiku. AccelerantHWInterface::GetModeList now works before SetMode has been called. Added MultiLocker from the sample code. HWInterface uses it now in preparation to being used from multiple instances of DisplayDriver.

\class DisplayDriver DisplayDriver.h
\brief Mostly abstract class which handles all graphics output for the server.
The DisplayDriver is called in order to handle all messiness associated with
a particular rendering context, such as the screen, and the methods to
handle organizing information related to it along with writing to the context
itself.
While all virtual functions are technically optional, the default versions
do very little, so implementing them all more or less required.
