This patch introduces gpu screens into screenInfo. It adds interfaces for adding and removing gpu screens, along with adding private fixup, block handler support, and scratch pixmap init. GPU screens have a myNum that is offset by GPU_SCREEN_OFFSET (256), this is used for logging etc. RemoveGPUScreen isn't used until "xfree86: add platform bus hotplug support". v2: no glyph pictures for GPU screens for now. v3: introduce MAXGPUSCREENS, fix return value check v4: fixup myNum when renumbering screens (ajax) v5: drop cursor privates for now.

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
