	syssrc/sys/kern: kern_sig.c kern_sysctl.c
	syssrc/sys/sys: sysctl.h

Log Message:
Add kernel logging of processes which exit on signals which can
cause a core to drop, and whether the core dropped, or, if it did
not, why not (i.e. error number). Logs process ID, name, signal that
hit it, and whether the core dump was successful.

logging only happens if kern_logsigexit is non-zero, and it can be
changed by the new sysctl(3) value KERN_LOGSIGEXIT. The name of this
sysctl and its function are taken from FreeBSD, at the suggestion
of Greg Woods in PR 6224. Default behavior is zero for a normal
kernel, and one for a kernel compiled with DIAGNOSTIC.
