Drop superfluous PKG_DESTDIR_SUPPORT, "user-destdir" is default these days.

Log message:
Simply and speed up buildlink3.mk files and processing.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Log message:
Move mk/emacs.mk to editors/emacs/modules.mk.

Don't call pkg_info to get the installed Emacs version; always use the
version matching EMACS_TYPE set by users.  Be DEPENDS to it.  This should
address pkg/37146 by Aleksey Cheusov.

While here convert some emacs lisp packages to user-destdir.

Log message:
Restructure the following packages:

	editors/xemacs-current
	editors/xemacs-current-nox11

The latter is now just editors/xemacs-current built with a specific set
of options.  Changes include:

+ Rename the "xaw" option to "lucid" to match the option \ 
name used in
  xemacs/options.mk.  Also comment out the "esound" option which isn't
  fully supported yet.  Add some comments to the options.mk file to
  make it a little easier to understand.

  XXX Should probably add a pgsql option as this version of XEmacs has
  XXX some sort of PostgreSQL support.  Also need to sort out native
  XXX sound support.

+ Remove Makefile.common and move all logic into xemacs-current/Makefile
  and xemacs-current/options.mk.

+ As of version 21.5, xemacs switched to using GNU autoconf, so set
  GNU_CONFIGURE=yes.

+ Include termcap.buildlink3.mk to properly deal with termcap/curses
  issues (xemacs needs termcap).  Drop the --without-ncurses setting
  as the issue is handled by termcap.buildlink3.mk.

+ Be slightly more aware of ${X11_TYPE} == "modular" by not referring to
  ${X11BASE} in that case.

+ Include buildlink3.mk files for zlib and gettext, which are detected
  automatically if they're in the base system.  Gettext is needed for
  MULE support.

+ In the Makefile and the PLIST, don't substitute for ${EMACSVER}.
  Instead substitute for ${DISTNAME} so the PLIST looks closer to
  xemacs/PLIST.

+ Add patch-al which handles a difference between bmake and gmake in
  using $< in a makefile target.

+ Support DESTDIR installation by adding INSTALL_MAKE_FLAGS to override
  where files are installed during the install phase.

+ Honor PKGMANDIR.

+ Bump the PKGREVISION for xemacs-current and xemacs-current-nox11 to 1.
  Both packages now track and use the same PKGREVISION number.

Log message:
Support XEmacs 21.5.x without X too.
