Implement more socket APIs, refer to #1336 and below PRs: - Implement wasi_addr_resolve function (#1319) - Fix socket-api byte order issue when host/network order are the same (#1327) - Enhance sock_addr_local syscall (#1320) - Implement sock_addr_remote syscall (#1360) - Add support for IPv6 in WAMR (#1411) - Implement ns lookup allowlist (#1420) - Implement sock_send_to and sock_recv_from system calls (#1457) - Added http downloader and multicast socket options (#1467) - Fix `bind()` calls to receive the correct size of `sockaddr` structure (#1490) - Assert on correct parameters (#1505) - Copy only received bytes from socket recv buffer into the app buffer (#1497) Co-authored-by: Marcin Kolny <mkolny@amazon.com> Co-authored-by: Marcin Kolny <marcin.kolny@gmail.com> Co-authored-by: Callum Macmillan <callumimacmillan@gmail.com>
