[BUG #6968] fixing various @ignore hints
[BUG #7395] some preparations to add file and line numbers to JSDoc issues

- let Comment.parse return parse issues as entries, with corresp. 'error' attributes
- process those in the calling layer, where usually node information is available
  (so you can get at file name and line number)
- it would still give the line number of the code node, not the exact line number
  in the JSDoc comment :-(
- not working yet (try with want_errors=True)
[BUG #6968] make @cldr a functor, to be consistent with other @-hints

- use the same parsing for @require, @use, @asset and @cldr

- left @require, @use processing in MClassDependencies.dependencies_from_comphints
  (not sure if this could also be integrated in MClassHints.getHints?!)
