Boris Zbarsky ffcfe5490a Bug 1209035. Fix incorrect "is this control focused?" checks in form code. r=smaug
For number controls, nsContentUtils::IsFocusedContent doesn't really do the
right thing, because the thing it thinks is focused is the anonymous text
element inside the number control.  As a result, we weren't properly updating
the state of the currently-focused number control when hitting enter in it to
submit the form.

The HTMLFormElement change is enough on its own to fix the bug.  The constraint
validation change is a just-in-case.

I haven't figured out a sane way to write a reftest for this, unfortunately:
the enter key press needs to look like a real user event to trigger the
submission behavior.
