This change introduces a new public API symbol: SSL_get_peer_addr().
The change is QUIC-only, there are no changes for TLS connections
- API: add peer address query for QUIC connections
* Internal: declare/implement ossl_quic_get_peer_addr(SSL*, BIO_ADDR*)
* Public: declare/implement SSL_get_peer_addr(SSL*, BIO_ADDR*)
Rationale:
- Allow applications to retrieve the remote UDP tuple for QUIC sessions
(e.g., logging, access control, diagnostics)
Provided documentation and test cases for SSL_get_peer_addr().
Set peer via channel API on new-conn.
- In ch_on_new_conn_common(), BIO_ADDR_copy(&ch->cur_peer_addr, peer)
was replaced with ossl_quic_channel_set_peer_addr(ch, peer) so
addressed_mode is enabled at connection bring-up.
Dropped redundant peer detection in create_qc_from_incoming_conn()
The peer address is now propagated in ch_on_new_conn_common() via
ossl_quic_channel_set_peer_addr(), so the channel is already in
"addressed" mode. This also avoids querying the (unconnected) server
UDP BIO, reduces duplication, and simplifies the accept path. All
regression tests pass.
