It's a rather useless interface:
* nsITextControlFrame is only implemented by nsTextControlFrame, so we
can just use that.
* nsIFormControlFrame had very few actual functionality, mostly
scattered around:
* SetFormProperty(select) was only useful for nsTextControlFrame.
* SetFormProperty(value) was only called on file controls.
* SetFocus() did mostly nothing, or things that can be done in
ElementStateChanged instead.
There are some do_QueryFrame calls that I replaced for better checks in
font inflation and nsIFrame, but I'll adjust to preserve behavior if you
insist (it just such a somewhat-random check).
