When the UDP tunnel compat code was written, it backported some
functions that were slated to be in the next kernel release, then
called 3.20. However, this was ultimately released as 4.0 instead.

With the latest change of separating vports into their own modules,
it is necessary to export all public functions in linux/compat/
directory. Also, we should prefix functions which replace the
upstream ones with 'rpl_' and others with 'ovs_'. This will prevent
the linker error when vport modules use those functions in the future.
e.g., the to be merged vport-stt module will use the flex_array_*
functions which are not currently exported.

Account for kernels which provide udp_sock_create() in an
insufficient version.
Avoids the following error when inserting openvswitch.ko on
respective kernels:
openvswitch: exports duplicate symbol udp_sock_create (owned by udp_tunnel)

Upstream commit:
udp: Do not require sock in udp_tunnel_xmit_skb
The UDP tunnel transmit functions udp_tunnel_xmit_skb and
udp_tunnel6_xmit_skb include a socket argument. The socket being
passed to the functions (from VXLAN) is a UDP created for receive
side. The only thing that the socket is used for in the transmit
functions is to get the setting for checksum (enabled or zero).
This patch removes the argument and and adds a nocheck argument
for checksum setting. This eliminates the unnecessary dependency
on a UDP socket for UDP tunnel transmit.

Upstream commit:
udp-tunnel: Add a few more UDP tunnel APIs
Added a few more UDP tunnel APIs that can be shared by UDP based
tunnel protocol implementation. The main ones are highlighted below.
setup_udp_tunnel_sock() configures UDP listener socket for
receiving UDP encapsulated packets.
udp_tunnel_xmit_skb() and upd_tunnel6_xmit_skb() transmit skb
using UDP encapsulation.
udp_tunnel_sock_release() closes the UDP tunnel listener socket.

Upstream commit:
udp: Add udp_sock_create for UDP tunnels to open listener socket
Added udp_tunnel.c which can contain some common functions for UDP
tunnels. The first function in this is udp_sock_create which is used
to open the listener port for a UDP tunnel.
