Merge branch 'full-bsd-osx-port' into 'master'

Full BSD/OSX port

This finishes up the OSX port by getting the full test suite running on OSX.  It also sets up an OSX CI job travis-ci.org, run as part of the github mirror here: https://github.com/f-droid/fdroidserver  You can see those CI builds here: https://travis-ci.org/f-droid/fdroidserver

This should translate entirely to *BSD since OSX's user land is merged with FreeBSD.
