. create signals-related struct message type to store sigset_t directly . create notify-specific message types, so the generic NOTIFY_ARG doesn't exist anymore . various related test expansions, improvements, fixes . add a few error-checks to sigismember() calls Change-Id: I53c18999b5eaf0cfa0cb25f5330bee9e7ad2b478
