commit 9140a24b312176ebb4e6eb6458b33ce640c04440
Author: Tom Lane <tgl@sss.pgh.pa.us>
Date:   Tue Nov 28 12:34:03 2023 -0500

    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.
