other tokens. This is only the first half of the conversion. The next step is
to drop the type attribute on most tokens and match on the constructor in the
token transform machinery.
* Add handler for post-expand paragraph wrapping on token stream, to handle
things like comments on its own line post-expand
* Add general Util module
* Fix self-closing tag handling in HTML5 tree builder
The TokenTransformDispatcher now actually implements an asynchronous, phased
token transformation framework as described in
https://www.mediawiki.org/wiki/Future/Parser_development/Token_stream_transformations.
Additionally, the parser pipeline is now mostly held together using events.
The tokenizer still emits a lame single events with all tokens, as block-level
emission failed with scoping issues specific to the PEGJS parser generator.
All stages clean up when receiving the end tokens, so that the full pipeline
can be used for repeated parsing.
The QuoteTransformer is not yet 100% fixed to work with the new interface, and
the Cite extension is disabled for now pending adaptation. Bold-italic related
tests are failing currently.

easy to compare the output on more complex articles. 181 tests passing after
adding two table tests with whitespace-only differences to the whitelist.
