sigwait.3: Note sigprocmask(2) requirement, explicitly link sigtimedwait(2)/NOTES
This comes from a real user complaint. sigwait(3) is the most obvious
of the family, and it doesn't mention any of the usage details.
Most of these can be crosslinked, but not mentioning the sigprocmask(2)
requirement is malice.
