i965g: add standalone xlib debug winsys

Create a dummy winsys that just debug-prints on calls into the winsys
functions.  Will use this to get to the point where we are generating
sane-looking debug dumps and diassembly.

Also fix various warnings generated with the new compiler flags set in
this config.
