The SCTP protocol allows to bind multiple address to a socket. That
feature is currently only exposed as a socket option. Add a bind_add

socket option from kernel

The APIs are being designed based upon
The only difference between a few missing fixes applied to the SCTP
one is that TCP uses ->getpeername to get the remote address, while
SCTP uses kernel_getsockopt(.. SCTP_PRIMARY_ADDR). But given that
getpeername is defined to return the primary address for sctp, there
doesn't seem to be any
