Fix compilation with OpenSSL 4 OpenSSL 4.0.0 changed some parameters and returnvalues to const, so we need to update our declarations and subsequently cast away const- ness from a few callsites to make libpq build without warnings. This is tested with OpenSSL 1.1.1 through 4.0.0 as well as with LibreSSL. No functional change is introduced, this commit only allows postgres to be compiled against OpenSSL 4.0.0 without warnings.
There is also an errormessage change in OpenSSL 4.0.0 which needed to be covered by our testharness. This will be backpatched to all supported branches since they are all equally likely to be built against OpenSSL 4.0.0 as it becomes available in distributions. Backpatching will be done once it has been in master for a few days without issues.
