Allocate XvMC surfaces in XvMC library other than in DDX driver. 

However 915/915GM requires physical address for XvMC surfaces (although
XvMC is disabled on 915/915GM under KMS, it is enabled under UMS),
currently DRM/GEM can't handle physical address which means we have to
use legacy way for 915/915GM (and I dislike using two paths for XvMC
surfaces in XvMC library).
