Previously, we used to scroll the text control's selection into view after a reframe. This had two problems: it was not precise (in case the selection was modified by the mouse, for example), and it lead to problems such as bug 629878 if the control's frame was reconstructed because of the control being moved inside the DOM. This patch disables that behavior by wrapping the selection scroll function into nsITextControlFrame::ScrollSelectionIntoView, so that APIs such as setSelectionRange on the text control's content node can still call it explicitly (since they actually need this behavior), but other callers of nsITextControlFrame::SetSelectionRange (such as the nsTextEditorState object's selection offset restoring mechanism) don't get this behavior as an undesired side-effect.
