Eric Anholt cade317d31 Overhaul of the ATI driver: 
- Add monochrome hardware cursor support.
- Try to auto-detect AGP support for DRI on Radeons. And fail. Detect it
    properly on R128.
- Set up card for pseudo-DMA if possible. Convert 2D rendering code to
    prepare DMA packets only. Use generic code to decode DMA packets to
    MMIO if PDMA is unavailable. Add WIP code to support "real" DMA without
    DRM support.
- Dispatch pending DMA commands when the server sleeps. Otherwise some
    things, such as typing in an xterm, wouldn't show up for a time.
- Fix Radeon Composite acceleration in many ways, and add Rage 128
    Composite acceleration. Disable them both due to still-not-understood
    issues they have. They fail with In, Out, AtopReverse, and Xor, and
    text rendering is strange.
- Add textured XV support for R100 and Rage 128. No brightness/sat
    controls, but it does support multiple ports, and cooperates with
    Composite.
- Add WIP code for hostdata uploads.
- Many cleanups and fixes.
