Merge DRI-trunk-20040613 changes in programs/Xserver/hw/xfree86/drivers, with

the following notes:

- Savage and Mach64 (= ati/ati*.[ch] changes) DRI not merged due to insecurity.
- VIA driver converted to new drmContext and drmHandle names.
- Radeon driver merge conflicted in many places, and MergedFB at least could
  probably use some checking at this point.
