A little history- the original intention was that the gallium code 
should stand on its own without dependencies on Mesa.  In the early days 
we even considered putting gallium in its own git repo.

That never happened but we kept the principle of gallium not having any 
outside dependencies.

Also, if there were no classic / non-gallium drivers today we'd probably 
be treating Mesa as one big gallium state tracker, and it would directly 
use the gallium utility code.

Anyway, today's reality is something else.  Refactoring things is 
desirable, but it's never as straightforward as you'd hope. 
Unfortunately, I haven't had much time to work on this, or think about 
it much.
