Bug fixes in aboutId assignment during DOM Fragment unpacking

* isForeignContent now flags content that is not originally
  present in the top-level page => transclusion and extension
  content. During DOM fragment unpacking, top-level children
  of the fragment are always re-assigned the fragment wrapper's
  about-id.

* For content that is not flagged isForeignContent (figures that
  are reused from cache, and all other users of dom-fragment
  including scoped parsing), the fragment DOM is walked and all
  about-ids are reassigned fresh about ids.

* From an earlier patchset (now unrelated to the bug fixes here)
  * Renamed older badly named isEncapsulatedElt helper
    to isFirstEncapsulationWrapperNode.
  * Left behind helper to recognize when a node is an
    encapsulation wrapper (in case it comes handy later on).

* No change in parser tests.

  TODO: We need a parser test with extensions in them.

  {{echo|<div>foo</div> <math>1+2</math> <div>bar</div>}} would
  not RT properly before this patch because the inner <math> node
  did not have the about-id as the surrounding <div>s. This patch
  fixes this.

  This should also fix a lot of the <timeline> regressions seen
  in latest RT testing.
