MFC r257805, r257806, r257807:

r257805:
  Add a 'mini-memstick.img' release target, which will use the
  'bootonly.iso' components to create a smaller memory stick image.

  This is useful for system recovery, where a full memstick.img image
  is not necessarily needed (or wanted).  In addition, it is possible to
  do bootonly-style installation, where the base.txz, kernel.txz, etc.
  are fetched from a remote source.

  Provide backwards-compatible target (mini-memstick), to keep in sync
  with the targets documented in release/Makefile.

r257806:
  Remove extra target from 'memstick' in r257805.

r257807:
  Update release(7) to include 'mini-memstick' target.

r257942:
  Fix a few style nits.

r258101:
  Since the doc/ toolchain conversion to docbook 5.0, JADETEX
  is no longer a valid option, so remove 'WITHOUT_JADETEX=yes'
  from PBUILD_FLAGS.

  While here, also remove 'WITHOUT_X11=yes', since it will
  cause a dependency conflict by requiring both print/ghostscript9
  and print/ghostscript9-nox11.

  Switch to OPTIONSNG format (WITHOUT_* -> OPTIONS_UNSET='FOO'),
  and unset the FOP option, which requires Java (although it is
  disabled by default).  Also unset the 'IGOR' option, since
  textproc/igor is a validation tool, not necessarily a dependency
  of the doc/ build itself.

  While here, reduce the line length of PBUILD_FLAGS.
