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.

ipv6_find_hdr() already fixed in newer upstram kernel by Ansis, we
can start using this API safely.
This patch also backports fix (ipv6: ipv6_find_hdr restore prev
functionality) to compat ipv6_find_hdr().

OVS required some extensions to ipv6_skip_exthdr() which have
since been accepted upstream. On kernels with these changes we can
now use the upstream version instead of our compatibility code.

This patch prepares ipv6_find_hdr() function so that it could be
able to skip routing headers, where segements_left is 0. This is
required for us to handle multiple routing header case correctly.

Implementation of the IPv6 'set' action depends on ipv6_find_exthdr()
function to find routing header. By looking at the routing headers,
it is possible to tell, whether L4 checksums will need to be
recalculated, whenever the destination address is changed in
the main IPv6 header.
This function will need to be customized so that it would skip all
routing headers, where segements_left is equal to 0.

We currently have a version of ipv6_skip_exthdr() which is
identical to the main one with the addition of fragment reporting.
We can propose our version for upstream and then use it directly
without duplication.
