linux-yocto: streamline support for multiple upstream repo types
In order to support repositories of various types (with or without meta data, branched, pristine, custom, etc) information about the type of processing that is required was passed to the processing phases via variables. The combination of variables involved in coordinating the processing creates a learning curve and overly complicates recipe extensions. With minor tweaks to the kern-tools, adding flexibility and keying off the existence of the meta branch it is possible to remove all of the variables that were added to support different repository types.
