Add support for EXA to the radeon driver. Building EXA and XAA support is

    controlled at compile time, plus the runtime option of Option
    "AccelMethod" "EXA" or "XAA". The XAA support appears to remain as
    before, while the EXA pieces need just a little more polishing. Notable
    features:
- Render acceleration working on Radeon 100 and 200-series with DRI on.
- DRI works with EXA Notable issues:
- DGA disabled in the EXA case.
- Backbuffer moves disabled in the EXA case.
- No textured XVideo.
- MMIO render acceleration is close but still has some issues.
- Memory pressure while using Composite is really troublesome with DRI on.
    This patch is based on an initial patch by Zack Rusin, with significant
    work by Benjamin Herrenschmidt and myself.
