dri2proto: Add DRI2GetParam requestHEADmaster
Bump protocol version to 1.4. Bump package version to 2.7. This new protocol request effectively allows clients to perform feature detection on the DDX. If I had DRI2GetParam in June 2011, when I was implementing support in the Intel DDX and Mesa for new hardware that required a new DRI2 attachment format, then I could have avoided a week of pain caused by the necessity to write a horrid feature detection hack [1] in Mesa. In the future, when the work begins to add MSAA support to the Intel DDX, having a clean way to do feature detection will allow us to avoid revisiting and expanding that hack.
