Shared libraries need to be shipped in separate packages with shlibs
information. Add libwutil1 and libwings2 packages and let libwings-dev
depend on them.
Use dh_prep instead of "dh_clean -k" (dh-clean-k-is-deprecated). However
do not replace instances of dh_clean without -k option. (Debian
bug590244). Build-Depend on debhelper 7.
was this ever used for anything? i checked a couple hundred dockapps,
no joy; there's nothing in debian (afaict) that build-depends on it,
so let's try doing away with it.
