  Log:
  BUF/BIO work, for removing the requirement of KVA mappings for I/O
  requests.
  
  Stage 1 of 8:
  
  	o Replace the b_pages member of the BUF structure with an embedded
  	  XIO (b_xio).  The XIO will be used for managing the BUF's page
  	  lists.
  
  	o Initialize the XIO at two main (only) points: 1) the pbuf code,
  	  which is used by the NFS code to create a temporary buffer; and
  	  bufinit(9), which is used by the rest of the BUF/BIO consumers.
