  Log:
  Refactor the existing machine-dependent sf_buf_free() into a machine-
  dependent function by the same name and a machine-independent function,
  sf_buf_mext().  Aside from the virtue of making more of the code machine-
  independent, this change also makes the interface more logical.  Before,
  sf_buf_free() did more than simply undo an sf_buf_alloc(); it also
  unwired and if necessary freed the page.  That is now the purpose of
  sf_buf_mext().  Thus, sf_buf_alloc() and sf_buf_free() can now be used
  as a general-purpose emphemeral map cache.
