Bug#969612: krfb: please transition to pipewire 0.3, initially in experimental

[Simon McVittie <smcv@debian.org>]

Package: krfb
Version: 4:20.08.1-1
Severity: normal
Control: block #966535 by -1

pipewire 0.3 has now hit experimental. As discussed in #966535 and
on #debian-kde, the first step for transition #966535 is to make sure
the few packages that currently B-D on pipewire 0.2 can be recompiled
with 0.3. It would be great if you could do this in experimental soon
(please close this bug with that upload), and either be ready to re-upload
to unstable when the transition starts, or accept a 0-day NMU with the
same change.

krfb seems to support both APIs upstream via some #ifdefs, so it should
just be a matter of applying this pseudo-patch:

-               libpipewire-0.2-dev [linux-any],
+               libpipewire-0.2-dev [linux-any],

and checking that the result builds (and, ideally, that it works).

Thanks,
