FFe: multiarch support of alsa-plugins dependencies

[Steve Langasek]

The alsa-lib and alsa-plugins packages were converted for multiarch earlier in the cycle, but the dependencies of alsa-plugins have not been, making it impossible in practice to use this in a multiarch context. The dependencies that need to be converted for multiarch to make alsa-plugins installable are:
  libjack0
  libpulse0
  libsamplerate0
  libspeexdsp1
  libsndfile1
  libwrap0
  libflac8
  libogg0
  libvorbis0a
  libvorbisenc2
  libasyncns0

None of these have plugin paths that require patching the library for backwards-compatibility; they're each a simple matter of fixing up the library to install to the correct path and tagging the library Multi-Arch: same. So the risk of regression is fairly small.

Note that the impact of not fixing this is that flashplugin is installable via multiarch, but can only output sound to alsa devices directly, not to pulseaudio.

How does this get tested to verify there's no regression?

Given that none of these libraries have plugins, regression testing should
be as simple as checking the output of ldd on all of
/usr/lib/$arch/alsa-lib/*.so to verify that the libraries are found, plus
verifying that packages which build-depend on each of these libraries can
still build. I'm converting the libraries in dependency order so already
testing the latter locally, and the 'ldd' check is trivial to run when it's
all done.

OK. FFe approved then. I'll let you do the LP magic if you feel so inspired.

tcp-wrappers has already been transitioned to multiarch in Debian; package synced.

    per-architecture buildinfo.gz files that prevent multiarch
    co-installability, and all this information is already available in the
    build logs.

Missed one library earlier (because it wasn't a dependency of libpulse0 until just now), libjson0. This is another trivial library, no plugin paths, not even any reverse deps. Is it ok if I convert this one too?

---------------
pulseaudio (1:0.99.1-0ubuntu2) oneiric; urgency=low

  * Build for multiarch:
    - libpulse{,-mainloop-glib}0{,-dbg} and libpulse-dev are Multi-Arch: same.
    - pulseaudio itself should be Multi-Arch: foreign, since it's a daemon.
    - drop dh-buildinfo build-dependency, incompatible with multiarch and not
      relevant in Ubuntu where we have build logs for all builds.
    - LP: #825342.
