Tom Lane c82207a548 Use BIO_{get,set}_app_data instead of BIO_{get,set}_data.
We should have done it this way all along, but we accidentally got
away with using the wrong BIO field up until OpenSSL 3.2.  There,
the library's BIO routines that we rely on use the "data" field
for their own purposes, and our conflicting use causes assorted
weird behaviors up to and including core dumps when SSL connections
are attempted.  Switch to using the approved field for the purpose,
i.e. app_data.

While at it, remove our configure probes for BIO_get_data as well
as the fallback implementation.  BIO_{get,set}_app_data have been
there since long before any OpenSSL version that we still support,
even in the back branches.

Also, update src/test/ssl/t/001_ssltests.pl to allow for a minor
change in an error message spelling that evidently came in with 3.2.

Tristan Partin and Bo Andreson.  Back-patch to all supported branches.

PostgreSQL Database Management System
=====================================

This directory contains the source code distribution of the PostgreSQL
database management system.

PostgreSQL is an advanced object-relational database management system
that supports an extended subset of the SQL standard, including
transactions, foreign keys, subqueries, triggers, user-defined types
and functions.  This distribution also contains C language bindings.

See the file INSTALL for instructions on how to build and install
PostgreSQL.  That file also lists supported operating systems and
hardware platforms and contains information regarding any other
software packages that are required to build or run the PostgreSQL
system.  Copyright and license information can be found in the
file COPYRIGHT.  A comprehensive documentation set is included in this
distribution; it can be read as described in the installation
instructions.

The latest version of this software, and related software, may be
obtained at https://www.postgresql.org/download/.  For more information
look at our web site located at https://www.postgresql.org/.
