net: support being a TCP server to unblock TCP fastboot
Make following changes to unblock TCP fastboot support:
1. Implement being a TCP server support
2. Introduce dedicated TCP traffic handler (get rid of UDP signature)
3. Ensure seq_num and ack_num are respected in net_send_tcp_packet
function (make sure existing wget_cmd code is reflected with the fix)
