[PATCH] Enable DRI2 extension for Xephyr

[Feng, Haitao]

Hi Tiago,

Thank you very much for your reply!

Actually Dodji is the creator of Xephyr DRI extension, he has promised to have a
code review on my Xephyr DRI2 extension code patch.

By following your link, I have submitted the request, the entry is 
https://bugs.freedesktop.org/show_bug.cgi?id=30197

after browsing the Xephyr bug entry, I find that I have fixed "Bug 27196 - Xephyr
1.7.5 crashes when used with -host-cursor option".

Thanks
-Haitao
