HP NonStop (currently) doesn't have setitimer().
As setitimer() is only used in cases of perceived latency and it doesn't affect
correctness, it gets disabled entirely if NO_SETITIMER is set.
HP NonStop does provide struct itimerval, but other platforms may not, so this
is taken care of in this commit too, by setting NO_STRUCT_ITIMERVAL.
