Subramanya Sastry 5874d9a5f1 More thumb roundtripping fixes.
* Looks like I misled myself in commit 88fc91 -- that wikitext
  roundtripped perfectly because it went through the 'src' route
  because it was a thumbnail with an explicit image which doesn't
  go through renderThumb -- so, the serializer simply spit out the
  original 'src' string and hence perfect rt :).
* More whitespace preserving fixes in LinkHandler.
* Also changed resource value in the img tag to use the original
  filename rather than the normalized capitalized filename.
* 2 more parsertests rt -- now upto 400.

Subramanya Sastry 88fc91a292 Next round of image roundtripping fixes
* Changed PrefixImageOptions so that thumb and thumbnail are
  distinct key-value pairs.  Without this fix, cannot distinguish
  between thumb=foo.jpg and thumbnail=foo.jpg
* Fixed link handler so whitespace is preserved around prefixed image
  options.
* Fixed figure handler to process the 3 different kind of image options:
  size, simple image options, and prefixed image options.
* There is a hack/fixme for "upright: aspect" prefixed image option
  which needs to be looked into.
* Still need to fix uppercasing of the image resource name.

With these fixes, the following wikitext roundtrips perfectly
(after newline breaks are removed)

[[Image:Foo.jpg|thumbnail = 'baby.jpg'|100x100px|center| alt =bbbbb|
upright=true|bottom|link='http://foo.bar'|
This is a [[Linked Caption]] in the image]]

Subramanya Sastry 11e7c1031a Created a constants object for extracting wikitext markup properties.
* For now, extracted image markup options out of the link handler.
* This info will also be used by the serializer.
* More properties/global constants can be moved into this structure
  over time.

Subramanya Sastry d9d584e1b8 Minor tweaks/fixes to LinkHandler
* Minor refactoring
* Cleared src in dataAttribs in renderThumb since we can serialize
  thumbs now (or at least we can once all bugs are fixed and missing
  pieces are handled).

Gabriel Wicke ff414ad825 Add generic source round-trip mode, and use it for plain images (for now)
Anything with data-gen="both" and dataAttribs.src defined serializes to
dataAttribs.src and drops its contents (if any). We can use this to round-trip
elements we don't properly parse or serialize yet. Without RDFa info, the
editor will not touch the contents after encountering data-gen="both".

Gabriel Wicke e1a7d10063 Fix round-tripping of invalid external links somewhat
* Don't consider them for auto-numbered links
* Don't insert a trailing space if the content is empty

These links are still wrapped in nowiki on round-tripping since the
valid/invalid url determination is done in the LinkHandler and not the
Tokenizer as it is configuration-dependent. Not incorrect for rendering (and
perhaps easier to understand for humans too), but might still introduce a
dirty diff. We'll still need reconciliation / damage tracking in the end ;)

Subramanya Sastry 8f216af2f5 Handle link tails properly.
- Added a tail json attribute for wikiLinks
- During serialization, this attribute is used to strip the tail from
  the link target and render it after the link

  [[hen]]s ==> <a ... data-mw="{gc:1, tail: 's'}" ...>hens</a>
           ==> [[hen]]s

- 2 more roundtrip tests green

Gabriel Wicke d918fa18ac Big token transform framework overhaul part 2
* Tokens are now immutable. The progress of transformations is tracked on
  chunks instead of tokens. Tokenizer output is cached and can be directly
  returned without a need for cloning. Transforms are required to clone or
  newly create tokens they are modifying.

* Expansions per chunk are now shared between equivalent frames via a cache
  stored on the chunk itself. Equivalence of frames is not yet ideal though,
  as right now a hash tree of *unexpanded* arguments is used. This should be
  switched to a hash of the fully expanded local parameters instead.

* There is now a vastly improved maybeSyncReturn wrapper for async transforms
  that either forwards processing to the iterative transformTokens if the
  current transform is still ongoing, or manages a recursive transformation if
  needed.

* Parameters for parser functions are now wrapped in abstract Params and
  ParserValue objects, which support some handy on-demand *value* expansions.
  Keys are always expanded. Parser functions are converted to use these
  interfaces, and now properly expand their values in the correct frame.
  Making this expansion lazier is certainly possible, but would complicate
  transformTokens and other token-handling machinery. Need to investigate if
  it would really be worth it. Dead branch elimination is certainly a bigger
  win overall.

* Complex recursive asynchronous expansions should now be closer to correct
  for both the iterative (transformTokens) and recursive (maybeSyncReturn
  after transformTokens has returned) code paths.

* Performance degraded slightly. There are no micro-optimizations done yet
  and the shared expansion cache still has a low hit rate. The progress
  tracking on chunks is not yet perfect, so there are likely a lot of unneeded
  re-expansions that can be easily eliminated. There is also more debug
  tracing right now. Obama currently expands in 54 seconds on my laptop.

Gabriel Wicke 8368e17d6a Biggish token transform system refactoring
* All parser pipelines including tokenizer and DOM stuff are now constructed
  from a 'recipe' data structure in a ParserPipelineFactory.

* All sub-pipelines of these can now be cached

* Event registrations to a pipeline are directly forwarded to the last
  pipeline member to save relatively expensive event forwarding.

* Some APIs for on-demand expansion / format conversion of parameters from
  parser functions are added:

  param.to('tokens/expanded', cb)
  param.to('text/wiki', cb) (this does not work yet)

  All parameters are additionally wrapped into a Param object that provides
  method for positional parameter naming (.named() or conversion to a dict
  (.dict()).

* The async token transform manager is now separated from a frame object, with
  the frame holding arguments, an on-demand expansion method and loop checks.

* Only keys of template parameters are now expanded. Parser functions or
  template arguments trigger an expansion on-demand. This (unsurprisingly)
  makes a big performance difference with typical switch-heavy template
  systems.

* Return values from async transforms are no longer used in favor of plain
  callbacks. This saves the complication of having to maintain two code paths.
  A trick in transformTokens still avoids the construction of unneeded
  TokenAccumulators.

* The results of template expansions are no longer buffered.

* 301 parser tests are passing

Known issues:

* Cosmetic cleanup remains to do
* Some parser functions do not support async expansions yet, and need to be
  modified.

Gabriel Wicke afa5b95bc1 Don't work around html5 library tokenizer attribute reordering
The HTML5 parser we are using to normalize expected HTML output in parserTests
reverses the order of attributes (see
https://github.com/aredridel/html5/pull/53 for the fix). Remove whitelist
entries concerned with this and use the proper order in external image
attributes.

http://www.whatwg.org/specs/web-apps/current-work/multipage/urls.html#url-manipulation-and-creation

Removed a few whitelisted test cases that are now passing directly.

The encoding canonicalization could also be moved to the Sanitizer. Doing this
early in token stream processing however has the advantage of providing further
transformations uniform data to work with. We could even consider to move this
even further into the tokenizer.
