this just so we can rely on 2.8 to build the server/mesa against.

dri2proto: add prime protocol support. (v2.1)
So we reserve bits 16->19 for offload device ids, this means we can
have 6 offload devices, which is plenty for now, and we can bump
this further later without fear.
v2: I suck at maths, that is all. Fixed up the maths to match reality.
v2.1: fix typo

dri2proto: Add DRI2GetParam request
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.

dri2proto: Fix documented opcodes
Fix the documented opcodes in dri2proto.txt to be consistent with the
actual opcode values in dri2proto.h and in xcb/proto:src/dri2.xml. (It
looks like the opcodes were incorrect due to copy-paste errors).
