modular xorg.
- supply corresponding USE_XORG for all imake-using ports that need it
- USE_IMAKE no longer implies USE_XLIB in absence of USE_XORG
- retire USE_X_PREFIX which is not really used anywhere after the
above change
- a few minor nits like whitespace and SF macro

USE_MOTIF and generates a LIB_DEPENDS to x11-toolkits/open-motif. As
before, it implies USE_XPM (and therefore USE_XLIB). Motif-dummy is
removed from PKG_IGNORE_DEPENDS, whose sole resident is now XFree86-3.
Most of the simple ".if defined(HAVE_MOTIF)"s are removed to always
have USE_MOTIF. ftp/moxftp will define USE_MOTIF unless
WANT_ATHENA_VERSION (new variable) is defined. I merged the X cases
in cad/mars, so USE_MOTIF is used iff WITHOUT_X11 is not defined.
I will remove x11-toolkits/Motif-dummy (which has been repo copied to
open-motif) in a few days.
