Merge avahi 0.7 with Debian

Here's the merge I started on as a patch against the Debian package.

Debian bug #878911 is marked as fixed ...

The merge would probably fix our FTBFS issue.

It does not.

This bug was fixed in the package avahi - 0.7-3ubuntu1

---------------
avahi (0.7-3ubuntu1) bionic; urgency=low

  * Merge from Debian unstable (LP: #1735960). Remaining changes:
    - Add udebs corresponding to libavahi-common3 and libavahi-core7, for
      maas-enlist-udeb.
  * debian/patches/no-systemd-also.patch: Don't use 'Also=' in dnsconfd
    systemd unit. Closes: #878911.

avahi (0.7-3) unstable; urgency=medium

  * Brown paper bag release.
  * Don't hard-code architecture in gir1.2-avahi-0.6.install.
    Otherwise we FTBFS on everything but amd64.

avahi (0.7-2) unstable; urgency=medium

  * Drop shlibs files.
    Those are no longer necessary as all libraries provide symbols files
    nowadays.
  * Enable gobject introspection support.
    The typelib files for libavahi-gobject are split into a new package
    named gir1.2-avahi-0.6.
  * Handle socket activation in avahi-daemon-check-dns.sh when using systemd.
    To completely stop avahi-daemon under systemd the avahi-daemon.socket
    unit needs to be stopped as well. (Closes: #847456)

avahi (0.7-1) unstable; urgency=medium

  [ Andreas Henriksson ]
  * New upstream version 0.7
    - All default rlimits have been removed from avahi-daemon.conf.
      Those were causing crashes due to OOM and failure to start in LXC
      containers. (Closes: #841926, #856311)
  * Drop d/p/0001-avahi-autoipd-fix-dhclient-hooks-to-check-for-avahi-.patch
    - now included in upstream release.
  * Remove (Gtk+ 2.x) libavahi-ui{0,-dev} packages (Closes: #870785)
  * Add patch to also install manpages when not building gtk2
    - debian/patches/fix-manpage-install-conditions.patch
  * Remove libavahi-qt4-{1,dev} packages (Closes: #874832)
  * Stop shipping /usr/share/avahi/service-types
  * Add one new symbol to libavahi-gobject0.symbols

  [ Michael Biebl ]
  * Update (build-)dependencies for the switch from pygtk2 to pygobject/gtk3
  * Setup gbp pq to use patches without patch numbers
  * Add missing bshell.1 symlink (Closes: #655190)
  * Fix reference to avahi-autoipd.action(8) in avahi-autoipd(8)
    (Closes: #840833)
  * Do not install upstream ChangeLog file.
    It is autogenerated by gettexize and doesn't contain any useful
    information. It also breaks multi-arch and reproducibility.
    For user visible changes please consult the NEWS file instead.
    (Closes: #804134)
  * Bump Standards-Version to 4.1.0
  * Bump debhelper compat level to 10
  * Explicitly disable introspection support.
    We don't provide any introspection packages yet (but might in the
    future). For the time being use --disable-introspection to get more
    reliable build results.
  * Switch to dh_missing and abort on uninstalled files
  * Use /usr/share/dpkg/architecture.mk include to get DEB_HOST_ARCH_OS

avahi (0.6.32-2) unstable; urgency=medium

  [ Christian Hofstaedtler ]
  * Ensure dhclient exit hook does not trigger an error if avahi-autoipd is
    not running. (Closes: #852256)
