Modified Files:
	src/sys/kern: kern_sig.c
	src/sys/sys: siginfo.h

Log Message:
Add the notion of an "empty" ksiginfo_t (one where on signo is filled in).
Add an initializer for them: KSI_INIT_EMPTY
Add a predicate for them: KSI_EMPTY_P
Don't bother storing empty ksiginfo_t's since they have no information.
Change uses of KSI_INIT to KSI_INIT_EMPTY where no other information other
than the signo is being filled in.
