to 21.5.9 "brussels sprouts"

The main thrust of this release is the new GC algorithms.  If you want
to test this out configure with '--use-kkcc'.

to 21.5.8 "broccoli"

Lots of fixes and changes.  This release is primarily been done to
make way for the new GC stuff from Mike Sperber.

   -- Type names should be relatively short, with the first letter
      capitalized and no underscores if they can be avoided.
   -- "*count" == zero-based quantity.  Includes sizes, offsets, and indexes.
   -- "*bpos" == one-based buffer position.
