Subject: Metalink: message updates

Print "parsing (...) OK" only when no warnings are generated.  If
no file is found in Metalink, treat it FAILED.

If no digest is provided, print WARNING in parse_metalink().
Also print validating FAILED after download.

These changes make tests 2012 to 2016 pass.
