* New commandline parameter --mirror-pmOS, where the binary repository URL for postmarketOS can be specified (empty by default as of now, this will be filled with the real URL once the repo works) * Do not build packages, when they are in the binary repository and the version of the package in the binary repository is up-to-date. * Add a testcase for pmb.build.is_necessary().
