Subramanya Sastry 167dac7979 Introduce Parsing/DOM scopes for content fragments ... * Added mechanism to parse a set of tokens in its own parsing scope all the way to DOM (which in turn restricts token transformations to just that scope). This is equivalent to enforcing well-balanced requirements in restricted contexts (Ex: link content, image captions for starters). This also provides an option of enforcing balanced templates in certain contexts. This patch applies it to link content and image captions. Deleted the hacky closeUnclosedBlockTags code for dealing with bad HTML in captions. * Refactored common/duplicate code out of Cite handler and Template handler. * Updated DSR handling for dom-fragments which eliminates the warnings about cs/s dsr mismatches seen on image reuse. it:Dalmine used to get a bunch of DSR inconsistency warnings when dom-fragments were reused (reported in bug 53071) and are now fixed with this patch. * There is still one big hole in DOM fragment unpacking that has to be fixed. This pertains to improper tag nesting that will be broken up by the tree builder. The DOM fragment unpacker has to recognize these scenarios and fix up the DOM (either by fixing up the final DOM or by stripping mis-nested tags in the DOM fragment being unpacked). This patch has an incomplete hack for this that addresses the common-use case of nested a-tags generated by wikitext of this form: "[http://foo.bar a [[Wikilink] here]".
