Recent OpenBSD (at least 5.9 and up) has a version of getopt(3) that will not cope with the "-:" spec we use to accept double-dash options in postgres.c and postmaster.c. Admittedly, that's a hack because POSIX only requires getopt() to allow alphanumeric option characters. I have no desire to find another way, however, so let's just do what we were already doing on Solaris: force use of our own src/port/getopt.c implementation. In passing, improve some of the comments around said implementation. Per buildfarm and local testing. Back-patch to all supported branches.

* Postgres files that use getopt(3) always include this file.
|
|
* We must cope with three different scenarios:
|
|
* 1. We're using the platform's getopt(), and we should just import the
|
|
* appropriate declarations.
|
|
* 2. The platform lacks getopt(), and we must declare everything.
|
|
* 3. The platform has getopt(), but we're not using it because we don't
|
|
* like its behavior. The declarations we make here must be compatible
|
|
* with both the platform's getopt() and our src/port/getopt.c.
