We agreed with ncopa on #alpine-devel (2017-12-01 16:20 UTC) to
periodically purge aports in unmaintained that haven't been touched
in last 1 year (2 releases).

This moves all packages from testing to unmaintained which have not been
updated for atleast 6 months. If you are affected by this commit please follow
this proceddure:

* make sure your packages build on all architectures
* move your pacakge(s) back to testing
* if you want to keep this package and can maintain it (or find somebody to
  maintain it for you) for a minimum of 6 months ask it to be moved to community
