util: Move ralloc to a new src/util directory.

For a long time, we've wanted a place to put utility code which isn't
directly tied to Mesa or Gallium internals.  This patch creates a new
src/util directory for exactly that purpose, and builds the contents as
libmesautil.la.

ralloc seemed like a good first candidate.  These days, it's directly
used by mesa/main, i965, i915, and r300g, so keeping it in src/glsl
didn't make much sense.
