Bug#178203: xlibs: shlibs generate two xlibs dependencies with dpkg-shlibdeps

[Jeroen van Wolffelaar <jeroen@wolffelaar.nl>]

retitle 178203 dpkg-gencontrol should report only the strictest of multiple versioned dependencies on the same package
thanks

Actually, this problem is more broad than only within shlibdeps. For
example, my package for a certain reason _requires_ libbaz (>= 2.2), but
shlibdeps gives >=2.1. Then I specify:

Depends: libbaz (>= 2.2), ${shlibs:Depends}

with yields duplicates. More commonly occurs if you have
${misc:Depends}, which typically adds a certain debhelper version, but
you might be for any other reason requiring an even newer one.

So, I propose to add code to dpkg-gencontrol, which does the substvar
substitution which causes those duplicates, to handle this issue, which
also very likely leads to a more clean solution.
