Global signal dispositions.
Although they should not change the
default behaviors of signals for cthread programs, these patches add
new functions which can be used by libpthread to enable
POSIX-conforming behavior of signals on a per-thread basis.
e407ae3 Hurd signals: implement global signal dispositions
38eb4b3 Hurd signals: provide a sigstate destructor
344dfd6 Hurd signals: fix sigwait() for global signals
fb055f2 Hurd signals: fix global untraced signals.
