After bug 769967, FindUserSelectAllNode always returns nullptr. So we get rid of this method. Also, AreaRestriction is used by this, so it is unnecessary now.

Giving '0' (literal zero) to RefPtr is now ambiguous, as both
RefPtr(decltype(nullptr)) and RefPtr(T*) could be used.
In any case, our coding standards mandate the use of 'nullptr' for pointers.
So I'm changing all zeroes into nullptr's where necessary.

Perhaps, there may be better name like WhitespaceRunObject or something, however, for now keep using the term because I don't understand well what it does.
With this patch, following objects are renamed:
nsWSRunObject -> mozilla::WSRunObject
WSType -> mozilla::WSType
nsWSRunObject::WSFragment -> mozilla::WSRunObject::WSFragment
nsWSRunObject::WSPoint -> mozilla::WSRunObject::WSPoint
