[poky] [RFC PATCH 03/21] bb.fetch2: revise the Fetch.unpack API

[Yu Ke]

change the unpack to use the urldata and rootdir parameter
- urldata is the FetchData instance
- rootdir is the dir to put the extracted source. the original unpack
  use current dir (os.getcwd) as destination dir, which is not flexible
  and error-prone (error will occur if caller not chdir to dest dir)
