Reviewed by Ryosuke Niwa and Chris Dumez.

The code is largely structured like the HTML Standard, except we
currently do not fake an end tag as needed for m_scriptToProcess to be
properly assigned to.

As foreign content supports self-closing start tags we also have to
pretend the start tag is a non-self-closing one. This results in some
slight code smell, but it seems acceptable enough.

Gecko does this correctly already.
