use netbsd <sys/signal.h> and sigset_t

Browse Source 
. 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
	. rename kernel call specific signals fields to SYS_*
