nfs.stp, nfs_proc.stp, nfsd.stp, rpc.stp, scsi.stp, signal.stp,
socket.stp, task.stp, tcp.stp, vfs.stp: Protect pointer dereferences
with kread wherever possible. Some places still have hazards, as
marked with FIXMEs.
* errno.stp (returnstr): Don't use return in tapset C functions.
* aux_syscalls.stp (__uget_timex_m): Ditto.
