Remove UNIQUENAME and LATEST_LINK.

UNIQUENAME was never unique, it was only used by USE_LDCONFIG and now,
we won't have conflicts there.

Use PKGBASE instead of LATEST_LINK in PKGLATESTFILE, the *only* consumer
is pkg-devel, and it works just fine without LATEST_LINK as pkg-devel
has the correct PKGNAME anyway.

Now that UNIQUENAME is gone, OPTIONSFILE is too. (it's been called
OPTIONS_FILE now.)

Revert revision 1.3 it breaks "make -V PKGNAME" (possibly others too)

The check for WITH_DBUS && WITHOUT_X11 can be done in the
Makefile of the master port.  It doesn't really help to have the
same check repeated in all the slave ports.  Updating multiple
places is actually worse.

When dbus is already installed on FreeBSD 6.X emacs-nox11 may
pick it up as a dependency and fail to link with the proper
threading libraries too.

Assign LATEST_LINK to apropriate directory names for ports:
. editors/emacs;
. editors/emacs-devel;
. editors/emacs-nox11;
. editors/emacs22.
