Vassil Vassilev 19765fb68c [modules] Teach the ASTWriter to ignore mutations coming from the ASTReader.
Processing update records (and loading a module, in general) might trigger
unexpected calls to the ASTWriter (being a mutation listener). Now we have a
mechanism to suppress those calls to the ASTWriter but notify other possible
mutation listeners.
