Additionally, a few more simple time-based magic words are added in

values. This includes comments, templates and template arguments.
This also replaces the specialized expansion logic in the TemplateHandler. The
removal of link validation lets one more parser test fail for now. External
link target validation will need to be implemented in the token stream handler
for links. This is noted as TODO in

consolidate that area.

to drop the type attribute on most tokens and match on the constructor in the
token transform machinery.

Wohoo!
Complex pages with templates won't render properly yet, as noinclude /
includeonly and parser functions are not yet implemented. As a result, the
parser will run out of memory or hit the currently low expansion depth limit
as it tries to expand documentation for all templates.
disable it by default in parserTests as it tries to fetch all sorts of parser
functions and is not yet fully supported in parserTests. The next step will be
to build a list of parser functions (to avoid fetching them as templates) and
pushing the event interface into parserTests.
* Created AttributeTokenTransformManager for generic attribute conversion, and
removed { title, template argument {key, value} } expansion from
TemplateHandler.
* Added caching for attribute and input sub-pipelines. Especially attribute
pipelines would otherwise be recreated for each attribute value and key.
* TokenTransformDispatcher is now renamed to TokenTransformManager, and is
also turned into a base class
* SyncTokenTransformManager and AsyncTokenTransformManager subclass
TokenTransformManager and implement synchronous (phase 1,3) and asynchronous
(phase 2) transformation stages.
* Communication between stages uses the same chunk / end events as all the
other token stages.
* The AsyncTokenTransformManager now supports the creation of nested
AsyncTokenTransformManagers for template expansion.
The AsyncTokenTransformManager object takes on the responsibilities of a
preprocessor frame. Transforms are newly created (or potentially resurrected
from a cache), so that transforms do not have to worry about concurrency.
* The environment is pushed through to all transform managers and the
individual transforms.
