Merge branch 'ingela/ssl/shrink-state' into maint
* ingela/ssl/shrink-state: ssl: Remove duplicate record_cb handling ssl: Add test case for continued handshake with a timeout ssl: Use gen_statem named timers to handle connection and recv timeouts ssl: Move and rename diffie_hellman_keys and srp_keys to kex_keys ssl: Move key_algorithm to handshake_env ssl: srp ssl: Rename ssl: Move diffie_hellman_params to handshake_env ssl: Move and rename psk_identity state record field ssl: Move premaster_secret to handshake_env ssl: Make flight_state DTLS specific ssl: Add private_key to connection_env ssl: Remove unused record field ssl: Add erl_dist_handle to connection_env ssl: Add negotiated_version to connection_env ssl: Add key exchange items to handshake_env ssl: Add hashsign_algorithm and cert_hashsign_algorithm to handshake_env ssl: Add downgrade handling to connection_env ssl: Create connection_env ssl: Handle renegotiation and extensions in handshake_env
