  Log:
  Clean up the XIO API and structure.  XIO no longer tries to 'track' partial
  copies into or out of an XIO.  It no longer adjusts xio_offset or xio_bytes
  once they have been initialized.  Instead, a relative offset is now passed
  to API calls to handle partial copies.  This makes the API a lot less confusing
  and makes the XIO structure a lot more flexible, shareable, and more suitable
  for use by higher level entities (buffer cache, pipe code, upcoming MSFBUF
  work, etc).
