non-backward compatible changes in the format of packing list and handle
them gracefully;
- fix a longstanding issue with symlinks handling. Instead of recording
checksum for the file symlink points to, record checksum for the value
returned by readlink(2). For backward compatibility increase packing list
format minor version number and provide a fallback to a previous behaviour,
if package in question was created with older version of pkg_* tools;
