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:
Mechanical changes to add DESTDIR support to packages that install
their files via a custom do-install target.

Import emacs-wiki version 2.70, provided by Marko Sch=FCtz.
I fixed some pkglint warnings.

Wiki is a concept, more than a thing.  It is a way of creating
document pages using plain text markup and simplified hyperlinking.
By typing a name in MixedCase, a hyperlink is automatically created to
the document "MixedCase".  Pressing return on that name will create
the file if it doesn't exist, or visit it if it does.  The markup used
by emacs-wiki is intended to be very friendly to people familiar with
Emacs.  Type C-h v emacs-wiki-publishing-markup after this mode is
loaded for how to get started.
