Bug#437675: dehs tags machine readable status

[Bluefuture <bluefuture@email.it>]

Actually i use in Dehs a simple function (dpkg based) to see if the
package is updated against upstream:

function is_updated ($up_vers,$debian_vers) {
if ($up_vers=='') return 0;
passthru("dpkg --compare-versions '$up_vers' eq '" .
vers_conv($debian_vers) . "'",$great);
if ($great!=0) return 1;
else return 0;
}

I see that in uscan upstream version has added another tag for dehs
called status. Actually is an human readable string. I think that
devscripts developer could add a machine readable also a coded machine
readable dehs tag for status so i could use directly uscan output for
version compare.

P.s. i cc this to pkg-devscripts team
