Fix up the use of package options in the Emacs packages:

(1) Get rid of "nox11" -- the concept of "no" in package options is
    expressed by negating an option; use "-x11" instead.

(2) Teach editors/emacs20 to use package options instead of EMACS_USE_POP,
    EMACS_USE_X, EMACS_USE_X_TOOLKIT and USE_INET6.  We now use similar
    options as the other emacs packages, i.e. "x11", "motif", "xaw",
    as well as "pop" and "inet6".

(3) Make the emacs*-nox11 packages simply remove all X11 options by
    setting PKG_OPTIONS.emacs appropriately and include the corresponding
    emacs Makefile.  This allows for modifications to the emacs "X11"
    versions to be automatically picked up by the "non-X11" versions.
    The two corresponding versions of emacs now share the same version
    numbering, including PKGREVISIONs.

Bump the PKGREVISIONs on all Emacs editor packages.
