itimer: Schedule silent NULL pointer fixup in setitimer() for removal
setitimer() should return -EFAULT if called with an invalid pointer
for value. The current code excludes a NULL pointer from this rule and
silently uses it to stop the timer. This violates the spec.
Warn about user space apps which rely on that feature and schedule it
for removal.
