Bug 1000675.  Don't always include nsContentUtils in example codegen, fix example header guards to not end with __, don't use fully-qualified names in argument types when those argument types are in the mozilla::dom namespace already, and include headers from mozilla/dom.  r=jst

Bug 959209 - Thunderbird should use toolkit autocomplete widget, not the XPFE one. r=neil
Bug 1001936 - Clear the value cache when the editor is being destroyed because it won't get updated when we don't have a bound frame; r=bzbarsky
Bug 997805 - Correctly restore the placeholder text after the editor object is re-attached to a text control as a result of a reframe; r=bzbarsky

Recomputing the placeholder visibility does not require the placeholder div
itself to be present, as the only information required for that is the current
value of the text control which is present either way.  This patch fixes
nsTextEditorState::ValueWasChanged and nsTextEditorState::UpdatePlaceholderVisibility
to that effect.

But the real fix is in nsTextEditorState::UpdatePlaceholderText, where after
setting the placeholder text on the anonymous div, we redo the placeholder
visibility computation.  Since this function can be called from
HTMLTextAreaElement::CreatePlaceholderNode during frame construction, the
GetValue function may return the wrong value since the editor has not properly
been set up yet, resulting in this bug.  And this function call is useless
anyway, because changing the placeholder text does not really affect the
result of the visibility computation, so there is no need to do this work
in the first place.
