[PATCH v2 0/7] liburing debian packaging fixes

[Eric Wong <e@80x24.org>]

3 new patches on top of the original series, this addresses
the issues noticed by Stefan in the original series.

I'm getting these warnings from dpkg-gensymbols, but AFAIK
they're not fatal:

  dpkg-gensymbols: warning: new libraries appeared in the symbols file: liburing.so
  dpkg-gensymbols: warning: some libraries disappeared in the symbols file: liburing.so.1
  dpkg-gensymbols: warning: debian/liburing1/DEBIAN/symbols doesn't match completely debian/liburing1.symbols

    +    While "debuild -us -uc" could also be used to avoid signatures,
    +    using "UNRELEASED" also helps communicate to changelog readers
    +    that the package(s) are not from an official Debian source.

         AFAIK the official Debian package is maintained separately at
         <https://git.hadrons.org/git/debian/pkgs/liburing.git>,
         and won't be affected by this change.
