userspace: add erspan tunnel support.
ERSPAN is a tunneling protocol based on GRE tunnel. The patch
add erspan tunnel support for ovs-vswitchd with userspace datapath.
Configuring erspan tunnel is similar to gre tunnel, but with
additional erspan's parameters. Matching a flow on erspan's
metadata is also supported, see ovs-fields for more details.
