- Prepare for merge with trunksarea-1-0-0-20010307-freeze

- Change variable names to be more consistent
- Fix bug in per-context creation routine
- Fix root-only permissions for get/setsareactx IOCTLs
- Back out incomplete gamma changes
- Fix some compilation warning messages
- Various code cleanups
- Disable per-context SAREA example code for Radeon This can be re-enabled
    when it is actually used by the driver. Look for '#ifdef
    PER_CONTEXT_SAREA' in the client-side and ddx Radeon driver.
