* This routine attempts to rewrite the DOM to maximize tag overlap
and thus minimize tag uses.
* This takes as input a set of tags which participate in the
minimization.
* Tested on the following example
<b><i><u><s>BIUS</s></u></i></b><b><i><s>BIS</s></i></b><b><u><s>BUS</s></u></b><u><i>UI</i></u>
with multiple combinations of the 2^4 possible variations of i,b,u,s
tags: [], ['i','b','u','s'], ['i'], ['b','s'], ['i','b','u']
- But, I am not fully sure if this implements the right behavior when
only a subset of inline tags are provided. Needs discussion and tweaking
as necessary.
* Also tested on few others:
<b>B</b><b><i>BI</i></b><b><i><u>BIU</u></i></b><b><i><u><s>BIUS</s></u></i></b>
<s><i><b>SIB</s></i></b><s><i><u>SIU</u></i></s><i><u>IU</u></i><i>I</i>
* The previous pairwise tag rewriting version fails on several of these
examples, so this new version is a definite improvement.
* No change in parserTests run (203 passing before and after).
* Possible improvements that could/should be undertaken:
- get rid of useless/idempotent add/remove of nodes that don't change
the DOM.
- ensure that node attributes post-restructuring are correct.

- This is implemented as a post-processing pass.
- Might require additional checks to verify rewriteability.
- Implemented as a pair-wise tag DOM minimization strategy,
i.e. it takes tag pairs (B, I) for ex, and attempts to
normalize the tree just for those tag pairs. Normalizing
across multiple tags is implemented as pairwise rewriting
across all pairs: Ex:(b,i), (b,u),(i,u) for (b,i,u)
- Copied over attributes as part of rewriting, but some of the
attributes lose their meaning on rewriting since tags are
reordered (ex: sourcePosn, sourceTagPosn). How do we handle this?
Output examples and possible issues to fix:
<i><b><u>biu</u></b></i><b><u>bu</u></b><u>u</u>
gets rewritten to:
<u><b><i>biu</i>bu</b>u</u>
But, the equivalent wikitext form:
'''''<u>biu</u>''''''''<u>bu</u>'''<u>u</u>
does not get rewritten because of parsing differences.
This wikitext gets parsed into:
<i><b><u>biu</u>'''</b></i><u>bu<b>u</b></u>
The extra ''' token in the middle thwarts DOM rewriting.
However, a slightly different version:
"'''''<u>biu</u>''<u>bu</u>'''<u>u</u>"
gets properly normalized to:
<u>'''''biu''bu'''u</u>
An alternative, but fun strategy to play with is to use the following
two normalization primitives: S(wap) and M(erge).
- S rewrites T1(T2(x)) into T2(T1(x))
(ex: <b><i>foo</i></b> ==> <i><b>foo</b></i>)
- M rewrites (T(x),T(y)) into (T(x,y)).
(ex: <b>foo</b><b>bar</b> ==> <b>foobar</b>)
The current rewriting strategy could possibly be re-implemented as S-M
rewriting. The problem to solve there would be to find an efficient
rewriting strategy that is guaranteed to lead to a normal form. I may
not play with it now, but just documenting it for later (to play with
in my spare time).
This commit is just as a record of fun/experimental code where I get to
learn details of JS, wikitext, parsing, and DOM manipulation. Next
version of this code will attempt to introduce minimal DOM restructuring
across multiple tags at once which can be more efficient.
gwicke: Removed now passing test from whitelist, and updated another whitelist
entry which is now improved.

This was caused by the fact that a non-structural leaf can not have children, which makes it appear incompatible as a sibling to an arbitrary structural element (like a paragraph) but since it can not contain content we can check that instead.

This fix only affects following transforms, of which there are few right now.
Also removed a stray token mutation in QuoteTransformer.
Change-Id: Id6d4adce944b06fc1a3651cfbf63fc2670125225
* 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.

I was using data.length to check if the range was out of bounds, but
this is a problem when using selectNodes() inside of tree sync code
(which happens when performing rebuilds). While tree sync is in
progress, the model tree and the linear model don't match, so we
shouldn't be looking at the linear model for information about the model
tree. Instead, get the length of the DocumentNode and use that.
