i965: Support images with aux buffers

Browse Source 
Previously images did not support any auxiliary compression surfaces
(CCS, MCS, or HiZ).  That's about to change.  This patch just adds the
fields to __DRIimageRec to make auxiliary surfaces possible.

v2 (Jason Ekstrand):
 - Add an aux_pitch parameter as well as aux_offset
