Add a sigfilter emulation hook. It is used at the beginning of kpsignal2()
so that a specific emulation has the oportunity to filter out some signals.
if sigfilter returns 0, then no signal is sent by kpsignal2().
There is another place where signals can be generated: trapsignal. Since this
function is already an emulation hook, no call to the sigfilter hook was
introduced in trapsignal.
This is needed to emulate the softsignal feature in COMPAT_DARWIN (signals
sent as Mach exception messages)
