i965: Support images with aux buffers

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
