This patch adds an API to bb.fetch2 to enable users to plug in an unpack tracer that can trace each source file back to its corresponding upstream source url, even when multiple upstream sources are combined together in the same unpack directory. This may be required for software composition analysis, license compliance, and detailed SBoM generation. This patch provides only the needed hooks in bb.fetch2 code and a dummy abstract class defining the API; users may load their own unpack tracer class by setting the BB_UNPACK_TRACER_CLASS config parameter.
