Remove dead setenv, unsetenv replacement code.
setenv() and unsetenv() are in SUSv3 and targeted Unix systems havethem. We still need special code for these on Windows, but that doesn'trequire a configure probe.This marks the first time we require a SUSv3 (POSIX.1-2001) facility(rather than SUSv2). The replacement code removed here was not neededon any targeted system or any known non-EOL'd Unix system, and wastherefore dead and untested.No need for vestigial HAVE_SETENV and HAVE_UNSETENV macros, because weprovide a replacement for Windows, and we didn't previously test themacros.Reviewed-by: Tom Lane <tgl@sss.pgh.pa.us>Reviewed-by: Greg Stark <stark@mit.edu>Reviewed-by: Robert Haas <robertmhaas@gmail.com>Reviewed-by: Andres Freund <andres@anarazel.de>Discussion:https://postgr.es/m/CA+hUKGJ3LHeP9w5Fgzdr4G8AnEtJ=z=p6hGDEm4qYGEUX5B6fQ@mail.gmail.com
