OpenSSL 3.6.1 diff

[Alex Strickland]

Hi

I upgraded my OpenSSL to 3.6.1 (to enable secure websockets). I could
not get a clean build because of some compiler errors (MSVC) with the
Harbour contrib code. I asked Claude to help and it seems to have done
quite a nice job. I've attached a diff.

Claude had this to say:

"The header fix is the most important — it restores the compat macros
that OpenSSL 3.0 provides for all the renamed accessor functions
(EVP_CIPHER_key_length → EVP_CIPHER_get_key_length, EVP_PKEY_size →
EVP_PKEY_get_size, sk_num → OPENSSL_sk_num, SSL_get_peer_certificate →
SSL_get1_peer_certificate, etc.). The version guards handle functions
that are truly no-ops since 1.1.0."

Thanks also to Budyanto for this required change:

{!HB_DYNBIND_OPENSSL&allmsvc&HB_COMP_VER>'1909'}libs=libssl-3 libcrypto-3

I really feel like a barbarian wandering around in a church when editing
Harbour code, but needs must.
