[PATCH 0/1 dri2] Bump dri2 version minor.

[Thomas Hellstrom]

This change should really have been done at an earlier time, and it should
probably be backported to the Xserver 1.7 branch.

Dri2 clients need to know whether to request a fake front or not.
As of some time ago, the DRI2 server side automatically adds a fake
front to window drawables if there previously was none. However, there
is currently no way for a client to know whether this feature is present
or not. This is to remedy that situation.
