Zack Rusin	965544150d	drm/vmwgfx: Refactor cursor handling ... Refactor cursor handling to make the code maintainable again. Over the last 12 years the svga device improved support for virtualized cursors and at the same time the drm interfaces evolved quite a bit from pre-atomic to current atomic ones. vmwgfx only added new code over the years, instead of adjusting/refactoring the paths. Export the cursor plane handling to its own file. Remove special handling of the legacy cursor support to make it fit within the global cursor plane mechanism. Finally redo dirty tracking because memcmp never worked correctly resulting in the cursor not being properly updated in the guest.
