Emilio Cobos Álvarez fb89acd3b5 Bug 1362907 - Make select use nsHTMLButtonControlFrame for layout. r=jfkthame,dholbert
This simplifies our combobox code a bit more:

 * Reflow() is only needed to compute the label isize.
 * Frame construction uses a setup more similar to <input type=file> to
   get the right frame tree, removing a bunch of special code.
 * Lots of special code removed all over the place.
