  SVN rev 205385 on 2010-03-20 16:16:13Z by jh
  
  Escape characters unsafe for XML output in GEOM class, instance and
  provider names.
  
  - Characters in range 0x01-0x1f except '\t', '\n', and '\r' are replaced
    with '?'. Those characters are disallowed in XML.
  - '&', '<', '>', '\'', '"' and characters in range 0x7f-0xff are
    replaced with XML numeric character reference.
  
  If the kern.geom.confxml sysctl provides invalid XML, libgeom
  geom_xml2tree() fails and utilities using it do not work. Unsafe
  characters are common in msdosfs and cd9660 labels.
