- Replace inline implementations of sigprocmask() with calls to

  kern_sigprocmask() in the various binary compatibility emulators.
- Replace calls to sigsuspend(), sigaltstack(), sigaction(), and
  sigprocmask() that used the stackgap with calls to the corresponding
  kern_sig*() functions instead without using the stackgap.
