to 21.5.10 "burdock"

Please accept my apologies for the very long wait between releases
this time around.  My PC chose the 21.5.10 development cycle to go up
in a sickening cloud of smoke. :-( (Steve Youngs <youngs@xemacs.org>)

Lots of updates from Ben Wing (as always), also from Andy Piper, Mike
Sperber, and Stephen Turnbull with lots of documentation updates and
fixes.  One new exciting addition in this release is that the LDAP and
PostgreSQL code has been extracted out of the core C code and moved to
DSO's.  We have Jerry James to thank/blame/worship for that.

-- Rename/redefine integral types -- Ben Wing
   -- See src/ChangeLog for details and rationale.
   -- All integral types that measure quantities of anything are signed.
   -- All quantity types boil down to EMACS_INT, except Hashcode,
      which is an unsigned value of the same size as EMACS_INT.
   -- 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.
   -- "Char" refers to internal-format characters, not to the C type "char".
