Bug #748:

- Add Render acceleration for Radeon 100 and 200-series cards, enabled by
    default. Notable performance gains include 27fps in cairogears instead
    of 6fps (compared to 50 with glitz), and my disks are now the
    bottleneck in an ls -lR in gnome-terminal. Only supported in DRI mode
    because the MMIO submission hangs the card so far, but the code is left
    in because it may be supportable soon.
- Add xorg.conf options to disable Render acceleration and to force the
    subpixel order in the server (Hui Yu).
Many thanks to Hui Yu at ATI for the code this was based off of, Michel
    Daenzer for bugfixes and suggestions, and LinuxFund for sponsoring the
    work.
