part 1.  Stop touching rv in DO_FOR_EACH_ROWGROUP on table rows collections.

This relies on GetTHead/GetTBodies/GetTFoot never returning an error except OOM. Could we replace GetTHead/GetTFoot with nsHTMLTableElement::GetSection (would need to make it public) and maybe have a nsHTMLTableElement::GetTBodies that returns a nsContentList*? nsHTMLTableElement::GetSection should also return a nsIContent*, but I disgress :-/.

> nsHTMLTableElement::GetSection should also return a nsIContent*

That would involve QIs at all the callsites.  I don't think that really helps anything.

I added public inline GetTHead and GetTFoot methods that take no args and don't fail and that call GetSection() appropriately.  I then made the existing GetTHead and GetTFoot use those, and made DO_FOR_EACH_ROWGROUP do likewise.

I added a TBodies() function that returns nsContentList and used it in DO_FOR_EACH_ROWGROUP as well.
