Add a tool to work on i915 hardware in user mode

Browse Source 
This is the beginning of a tool that transforms the i9x5 code to user
mode code. Consider this a very early stage although it does produce
two programs. Requires spatch 1.0 or greater.

To try it out, assuming you have an up-to-date spatch,
   sh transform
   make
   make broken

Please don't fall to the temptation to auto-magicize this process.
It's primitive for a reason. That said, suggestions welcome of course.
