do_unpack, do_patch: shift some responsibility around, clean things up
- Consolidate 'is this file a patch' logic - Move unpack functions from classes into oe.unpack - Move the unpacking message printing into do_unpack - Move the destination directory determination into do_unpack - Use subprocess's ability to pass in PATH and cwd rather than mangling the cmd - Use shutil.copy2/copytree for ordinary file "unpack" - Use the existing urldata from bb.fetch.init rather than re-decodeurl'ing the urls - Make handling of globs in url paths explicit rather than implicit, calling oe_unpack on each one, so showing an unpacking message to the user for each globbed file, rather than the entirety Signed-off-by: Chris Larson <chris_larson@mentor.com> Acked-by: Khem Raj <raj.khem@gmail.com> Acked-by: Tom Rini <tom_rini@mentor.com>
