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.

+# This Makefile fragment handles Emacs Lisp Packages (== ELPs).
+#
+# Note to users:
+#
+#	* Users choose one favourite Emacs version (default GNU Emacs 21).
+#
+#	* Emacs Lisp files are installed...
+#	  	GNU emacs
+#	  		-> ${PREFIX}/share/emacs/site-lisp/foo/...
+#		XEmacs
+#	  		->${PREFIX}/lib/xemacs/site-packages/lisp/foo/...
+#
+#	* You can't install an ELP for both Emacs and XEmacs
+#	  simultaneously.
+#
+#	* XEmacs package's names are prefix'ed by "xemacs-".
+#
+# Note to package developers:
+#
+#	* XEmacs package's names are prefix'ed by "xemacs-".
+#
+#	  This is to make sure ELPs for XEmacs keep their own dependency
+#	  tree (for example, if an ELP "bar" depends on another ELP "foo",
+#	  "xemacs-bar" depends on "xemacs-foo".  "foo" (installed for GNU
+#	  Emacs) is useless for "xemacs-bar" in this case.).
+#
+#	  Make sure too that "foo" and "xemacs-foo" conflict each other,
+#	  since they can share some files.  (Making all ELPs separately
+#	  installable for GNU Emacs/XEmacs might be possible.)
+#
+#	* Assume each ELP supports all Emacs versions by default.  If the
+#	  ELP supports only certain Emacs versions, define EMACS_VERSIONS
+#	  _ACCEPTED explicitly before including mk/emacs.mk.
+#
+# Variables for users:
+#
+#	EMACS_TYPE
+#		Description:
+#			The user's favourite Emacs version.
+#		Possible values:
+#			emacs21, emacs21nox, emacs22, emacs22nox, emacs20, xemacs215, xemacs215nox, xemacs214, xemacs214nox
+#		Default value:
+#			emacs22
+#
+# Variables ELPs can provide:

+#			needs at run-time.
+#		Possible values:
+#			base, leim
+#		Default value:
+#			<undefined>
+#
+#	EMACS_VERSIONS_ACCEPTED

+#
+# Variables provided for ELPs:

+#		Possible values:
+#			${PREFIX}/bin/emacs, ${PREFIX}/bin/xemacs
+#
+#	EMACS_ETCPREFIX
+#		Description:
+#			Path to the directory misc. files should be
+#			installed into.  ELPs should append a short
+#			name as a subdirectory.
+#		Possible values:
+#			${PREFIX}/share
+#	  		${PREFIX}/lib/xemacs/site-packages/etc
+#
+#	EMACS_FLAVOR
+#		Description:
+#			GNU Emacs (emacs) or XEmacs (xemacs).
+#		Possible values:
+#			emacs, xemacs
+#
+#	EMACS_INFOPREFIX
+#		Description:
+#			Path to the directory Info files should be
+#			installed into.  Unlike EMACS_ETCPREFIX or
+#			EMACS_LISPPREFIX, subdirectory is not needed.
+#		Possible values:
+#			${PREFIX}/${PKGINFODIR}
+#	  		${PREFIX}/lib/xemacs/site-packages/info
+#
+#	EMACS_LISPPREFIX
+#		Description:
+#			installed into.  ELPs should append a short name

+#	  		${PREFIX}/lib/xemacs/site-packages/lisp
+#
+#	EMACS_PKGNAME_PREFIX
+#		Description:

+#		Possible values:
+#			"", "xemacs-"
+#
+#	EMACS_VERSION_MAJOR
+#		Description:
