Some pixmaps (window pixmaps and scratch pixmaps) don't have the drawable->id set and thus DRI2 gets confused when using that field for looking up the DRI2 drawable. Go back to using privates for getting at the DRI2 drawable from a DrawablePtr. We need to keep the resource tracking in place so we can remove the DRI2 drawable when the X resource it was created for goes away. Additionally, we also now track the DRI2 drawable using a client XID so we can reclaim the DRI2 drawable even if the client goes before the drawable and doesn't destroy the DRI2 drawable.
