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:
_EMACS_VERSION_NOREV is no more.  Use _EMACS_VERSION_MAJOR.

Pointed out & patch submitted by Aleksey Cheusov.  Thanks!

Log message:
Introduce EMACS_BUILDLINK to decide if Emacs lisp file wrappers are really
created or not.  Packages that include other ELP's buildlink3.mk must define
EMACS_BUILDLINK.  Other packages don't create wrappers, which reduces build
time a lot.

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:
Convert to use PLIST_VARS instead of manually passing "@comment "
through PLIST_SUBST to the plist module.
