Remove configure probes for poll and poll.h.
poll() and <poll.h> are in SUSv2 and all targeted Unix systems havethem.Retain HAVE_POLL and HAVE_POLL_H macros for readability. There's anerror in latch.c that is now unreachable (since we always have one ofWIN32 or HAVE_POLL defined), but that falls out of a decision to keepusing defined(HAVE_POLL) instead of !defined(WIN32) to guard the poll()code.Reviewed-by: Tom Lane <tgl@sss.pgh.pa.us>Reviewed-by: Andres Freund <andres@anarazel.de>Discussion:https://postgr.es/m/CA+hUKGJ3LHeP9w5Fgzdr4G8AnEtJ=z=p6hGDEm4qYGEUX5B6fQ@mail.gmail.com
