[PATCH 7/8] glamor: add core profile support to EGL glamor. (v2)

[Dave Airlie]

From: Dave Airlie <airlied at redhat.com>

This breaks ABI unfortunately as we have to pass the core profile
info from the egl part of glamor to the glamor part of glamor.

v1.1: use version defines.
v2: let glamor work it out itself
