Regrettably revert the optimisation preventing lots of pointless Linux builds.

This was changed in 17e4118de4614ef0358bdcf4d7715f1a7c85d67e to not (pointlessly) build DoM when the packaging step would do it again. This, of course, breaks tests on Linux. There seems to be a few ways round this but nothing neat and simple enough to do at this point.

Fix debian unstable package.

2022-02-17T20:34:39Z

Fix appimage build.

2022-02-17T19:17:35Z

Inhibit dbgsym package creation in non-debug mode.

2022-02-17T08:59:36Z

Remove unnecessary build when packaging for Linux.

2022-02-17T08:59:36Z

Remove old dependencies.

2022-02-17T08:59:26Z

Build with an ffmpeg that includes libdav1d.

Go back to 10-year certificate validity periods (#2174).

2022-02-12T22:15:20Z

Mageia requires libcap-utils for setcap during installation (#2169).

2022-01-19T22:28:01Z

Bump libdcp to 1.8.6

Hopefully this fixes #2124, failure to play DCPs on Sony SRX320/LMT3000 due to it not liking empty tags in reel assets.
