net: Cleanup encap items in ip_tunnels.h
Consolidate all the ip_tunnel_encap definitions in one spot in the header file. Also, move ip_encap_hlen and ip_tunnel_encap from ip_tunnel.c to ip_tunnels.h so they call be called without a dependency on ip_tunnel module. Similarly, move iptun_encaps to ip_tunnel_core.c.
