[bitbake-devel] [PATCHv2] fetch2: print checksums when they are different then expected

[Martin Jansa]

* in form which can be copied into a recipe without modification
* like oe-classic did since:
  http://git.openembedded.org/openembedded/commit/?id=68abc465559a68e9201c9525be3c4acc6297eaed
* it shows them in right form when they are missing completely, but in
  more verbose form when different
* it needs to print that only when checksums were requested, e.g.
  fetching from sstate mirror sets both md5mismatch and sha256mismatch,
  but your checksums shouldn't be shown
