If we aren't doing a full refresh, when changes to an included/required file or an inherited class occur we need to update all of the files that depend on them. BitBake records these dependencies, so read them and record them against each recipe. At the moment this only handles dependencies within the same layer; that is probably sufficient to handle most changes for the purposes of extracting the data this application cares about. A future improved solution will probably involve making use of BitBake's cache rather than and parsing all layers and their dependencies rather than individual recipes. This change also adds -x/--nofetch and -n/--dry-run options for debugging as well as some further debug messages. Signed-off-by: Paul Eggleton <paul.eggleton@linux.intel.com>
