1) Add socket ops for SOCK_SEQPACKET type.
2) For receive, create another loop. It looks like
stream receive loop, but it doesn't call notify
callbacks, it doesn't care about 'SO_SNDLOWAT' and
'SO_RCVLOWAT' values, it waits until whole record is
received or error in found during receiving and it takes
care about 'MSG_TRUNC' flag.
3) Update some comments('stream' -> 'connect oriented').
