Make defining both PORTVERSION and DISTVERSION a DEV_ERROR.

There are two cases:

- The upstream versionning is compatible with our versionning, or using
  DISTVERSION's magic leads to a compatible PORTVERSION, use
  DISTVERSION.  If it is possible to use DISTVERSIONPREFIX and
  DISTVERSIONSUFFIX to make it compatible, use them.
- The upstream versionning is not compatible with our versionning, and
  DISTVERSION's magic does not lead to a correct PORTVERSION, then set
  PORTVERSION to the equivalent of our versionning, and set DISTNAME.
  It is possible to use a third variable where you store upstream's
  version and use it to compute PORTVERSION and/or DISTNAME, like the
  dns/bind9* ports do.
