Upgrade to 21.5 beta20 "cilantro" with help from xemacs-devel-mule upgrade
by Andrey Slusar. The same patch-configure.ac is used. Changes in patches
patch-mem-limits.h and patch-emacs.c are solved, but a bit differently in
source so remove them. Autoconf 2.59 is changed which changes a few
configure options names.

Revert to 21.5.17 because 21.5.18 was imported without sufficient testing
by yours truely and is causing lots of build problems. I plan to keep
working on 21.5.18 until all the bugs are eliminated.

Update to 21.5.8.
The patches patch-emacs.c and patch-mem-limits.h are no longer needed
because lim_data has been changed from an unsigned int to an unsigned
long, which should be big enough on all architectures which we support.
Make Andrey Slusar <anray AT inet DOT ua> the maintainer, since he kindly
offered to take over this port from me.
