When nsRange::*JS() is called, mCalledByJS is set to true. In such case, Selection::NotifySelectionListeners() may move focus or anyway, it calls selection listeners. Then, they may cause calling non-*JS() methods of the nsRange instance. In this case, nsRange treats the call as called by JS since mCalledByJS is still true.
For preventing this issue, before calling Selection::NotifySelectionListeners(), nsRange should set mCalledByJS to false.
This patch renames AutoCalledByJSSetter to AutoCalledByJSRestore and make it stop setting mCalledByJS automatically. So, AutoCalledByJSRestore works same as AutoRestore now.

Selection needs to be able to distinguish if every selection change is caused by JS (i.e., via Selection API) or the others.
This patch maps some methods of Range and Selection to *JS(). Each of them marks its instance as "used by JS" and calls corresponding method.
With this change, Selection::NotifySelectionListeners() can move focus only when it's caused by Selection API.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.
