sctp: add encap_port for netns sock asoc and transport
encap_port is added as per netns/sock/assoc/transport, and the
latter one's encap_port inherits the former one's by default.
The transport's encap_port value would mostly decide if one
packet should go out with udp encapsulated or not.
This patch also allows users to set netns' encap_port by sysctl.
v1->v2:
- Change to define encap_port as __be16 for sctp_sock, asoc and
transport.
v2->v3:
- No change.
v3->v4:
- Add 'encap_port' entry in ip-sysctl.rst.
v4->v5:
- Improve the description of encap_port in ip-sysctl.rst.
