Fix for:

37247 (nsbeta2+) - XIF DTD / HTMLContentSinkStream shouldn't add end tags
for IMG,PARAM,SOUND,INPUT..etc., ( leaf tags ).

r=akkana.

41427 (nsbeta2+) - Avoid transient style handling in a head context.
40408 (nsbeta2+) - Check for nsresult in nsFragmentContentSink::AddLeaf().
The HTMLTag array was,erroneously,going out-of-bounds for XMP tag.
40741 (nsbeta2+) - Text, only document, was getting sucked up into <!DOCTYPE>
40143 (nsbeta2+) - Use scanner's mIncremental memeber wisely when data is
supplied through document.write();
40552 (nsbeta2+) - Contain default <!DOCTYPE> to html documents only.

r=rickg

30617 (nsbeta2+) - Misplaced AREA tag should be informed with base target info.
