- bsp-cli: now depends on `base-files (>= ${REVISION})`, this way upgrading the bsp-cli causes our base-files to be installed
- bsp-cli no longer does gymnastics with /etc/os-release et al, all done in armbian-base-files now
- general/apt-utils.sh: introduce `apt_find_upstream_package_version_and_download_url()`
- base-files: add release to version, in order to comply with repo restrictions (valid repos can't have two different debs with same name and version, md5 must match)
