Make the libcrypto Version.map export the same symbol names as upstream
3.5.8.
Remove 52 names that upstream does not export:
- the internal threading and record layer functions (ossl_crypto_*, ssl3_cbc_*, tls1_cbc_*), which only libssl used;
- the internal WPACKET_quic_* functions;
- OPENSSL_cpuid_setup;
- ASN.1 item functions that are not in util/libcrypto.num.
Add 7 public names that were missing (ASYNC_get_mem_functions,
ASYNC_set_mem_functions, CMS_EnvelopedData_it, EVP_CipherPipeline*) to
OPENSSL_3_5_0, where the other symbols from upstream 3.1 to 3.5 are.
The version node names do not change. EC_GFp_nistp224_method,
EC_GFp_nistp256_method and EC_GFp_nistp521_method stay unexported
(6f6446b33064).
Compatibility: libssl.so.35 from earlier builds imports the removed
internal symbols, so it does not load with this libcrypto.so.35.
libcrypto and libssl must be updated together. This change needs the
previous libssl change, which gives libssl its own copies. On the test
host, nothing else in the base system (including lib32) imports a
removed symbol, and neither do the few installed ports.
Tested on arm64: the build links with --no-undefined-version. The
libcrypto exports match upstream except for the three nistp methods
above. libssl, the engines, the legacy provider and openssl(1) load
with LD_BIND_NOW=1.
