…thonGH-114573) * pythongh-114572: Fix locking in cert_store_stats and get_ca_certs cert_store_stats and get_ca_certs query the SSLContext's X509_STORE with X509_STORE_get0_objects, but reading the result requires a lock. See openssl/openssl#23224 for details. Instead, use X509_STORE_get1_objects, newly added in that PR. X509_STORE_get1_objects does not exist in current OpenSSLs, but we can polyfill it with X509_STORE_lock and X509_STORE_unlock. * Work around const-correctness problem * Add missing X509_STORE_get1_objects failure check * Add blurb (cherry picked from commit bce6931) Co-authored-by: David Benjamin <davidben@google.com>
