In kern_sigtimedwait(), move initialization code out of process lock,
instead of using SIGISMEMBER to test every interesting signal, just
unmask the signal set and let cursig() return one, get the signal
after it returns, call reschedule_signal() after signals are blocked
again.

In kern_sigprocmask(), don't call reschedule_signal() when it is
unnecessary.

In reschedule_signal(), replace SIGISEMPTY() + SIGISMEMBER() with
sig_ffs(), rename variable 'i' to sig.
