Bug 1190882: If the focused accessible is removed from the tree, fire a11y focus on the document. r=eeejay

If the DOM focus is removed before something else is focused, the document gets DOM focus, but no blur event is fired (bug 559561).
This means that no a11y focus event is fired, so clients aren't notified.
This is particularly problematic for screen readers when dismissing some ARIA dialogs, as the screen reader doesn't know that focus has returned to the top level document.

We destroy them manually, so it's the right thing to do.

This allows us to not run destructors of any members of nsStyle*, which in turn allows us to:

 * Remove the hack that replaced all nsStrings for nsStringReprs.
 * Remove ns{,C}StringRepr (followup)
 * Add members with destructors to the style structs (you see where I'm going :)).

XPIDL has the requirement that [scriptable] interfaces with [notxpcom]
methods or attributes are [builtinclass]. Currently, if you don't
explicitly mark something builtinclass when it should be, then the
XPIDL compiler will just silently treat it like builtinclass. This
means that you can cause the JS implementation of an XPCOM to start
failing without any warning by marking a method notxpcom.

This patch instead makes it an error. A prior patch fixed the existing
instances in the tree that relied on the implicit behavior.

I also added a test that we reject such classes missing builtinclass
at compile time, as well as classes that inherit from builtinclass
interfaces without themselves being builtinclass. I left behind a part
of the runtime test for this behavior, but now this test just ensures
that you can't implement a [builtinclass] interface in JS.
