Bartosz Dziewoński 8e44b43df0 Split off ThreadItemSet from CommentParser
Goal:
-----
Finishing the work from Iadb7757debe000025e52770ca51ebcf24ca8ee66
by changing CommentParser::parse() to return a data object, instead of
the whole parser.

Changes:
--------
ThreadItemSet.php:
ThreadItemSet.js:
* New data class to access the results of parsing a discussion. Most
  methods and properties are moved from CommentParser with no changes.

CommentParser.php:
Parser.js:
* parse() returns a new ThreadItemSet.
* Remove methods moved to ThreadItemSet.
* Placeholder headings are generated slightly differently, as we process
  things in a different order.
* Grouping threads and computing IDs/names is no longer lazy. We always
  needed IDs/names anyway.
* computeId() explicitly uses a ThreadItemSet to check the existing IDs
  when de-duplicating.

controller.js:
* Move the code for turning some nodes annotated by CommentFormatter
  into a ThreadItemSet (previously a Parser) from controller#init to
  ThreadItemSet.static.newFromAnnotatedNodes, and rewrite it to handle
  assigning parents/replies and recalculating legacy IDs more nicely.
* mw.dt.pageThreads is now a ThreadItemSet.
