I didn't want to change the interface of view_query_is_auto_updatable()
because this might be called from other third-patry software, so I renamed
this function to view_query_is_auto_updatable_or_lockable() and added the flag
to this. I created view_query_is_auto_updatable() as a wrapper of this function.
I also made view_query_is_lockable() that returns a other message than
view_query_is_auto_updatable().

I adopted #1 and I didn't change anything about this.
