ec8544f744 Simplify the sf_buf implementation. In short, make it a trivial veneer 
over the direct virtual-to-physical mapping.

e45db9b837 - Modify alpha's sf_buf implementation to use the direct virtual-to- 
physical mapping.
 - Move the sf_buf API to its own header file; make struct sf_buf's
   definition machine dependent.  In this commit, we remove an
   unnecessary field from struct sf_buf on the alpha, amd64, and ia64.
   Ultimately, we may eliminate struct sf_buf on those architecures
   except as an opaque pointer that references a vm page.
