Subject: pkg_depends: fix version constraints

* factor parsing version constraint to str_to_constraint and use that
  from pkg (pkg_version_satisfied) and also pkg_depends (parseDepends)
* fix constraint_to_str(), for EARLIER and LATER it was using '<' and
  '>' which is parsed later as EARLIER_EQUAL and LATER_EQUAL
* show notice when deprecated '<' or '>' is used
