selftests/net: Add TCP-AO + TCP-MD5 + no sign listen socket tests
The test plan was (most of tests have all 3 client types): 1. TCP-AO listen (INADDR_ANY) 2. TCP-MD5 listen (INADDR_ANY) 3. non-signed listen (INADDR_ANY) 4. TCP-AO + TCP-MD5 listen (prefix) 5. TCP-AO subprefix add failure [checked in setsockopt-closed.c] 6. TCP-AO out of prefix connect [checked in connect-deny.c] 7. TCP-AO + TCP-MD5 on connect() 8. TCP-AO intersect with TCP-MD5 failure 9. Established TCP-AO: add TCP-MD5 key 10. Established TCP-MD5: add TCP-AO key 11. Established non-signed: add TCP-AO key Output produced: > # ./unsigned-md5_ipv6 > 1..72 > # 1592[lib/setup.c:239] rand seed 1697567046 > TAP version 13 > ok 1 AO server (INADDR_ANY): AO client:
