Update the necessary make and configure files to remove the Linux
datapath and then remove the datapath.
Move datapath/linux/compat/include/linux/openvswitch.h to
include/linux/openvswitch.h because it is needed to generate header
files used by the userspace switch.
Also remove references to the Linux datapath from auxiliary files
and utilities since it is no longer supported.

Recent changes in Linux kernel TC action subsystem introduced new
TCA_ACT_FLAGS_NO_PERCPU_STATS flag. The purpose of the flag is to request
action implementation to skip allocating action stats with expensive percpu
allocator and use regular built-in action stats instead. Such approach
significantly improves rule insertion rate and reduce memory usage for
hardware-offloaded rules that don't need benefits provided by percpu
allocated stats (improved software TC fast-path performance). Set the flag
for all compatible actions.
Modify acinclude.m4 to use OVS-internal pkt_cls.h implementation when
TCA_ACT_FLAGS is not defined by kernel headers and to manually define
struct nla_bitfield32 in netlink.h (new file) when it is not defined by
kernel headers.

OvS includes compat code for several TC actions including vlan, mirred and
tunnel key. MPLS actions have recently been added to TC in the kernel. In
preparation for adding TC offload code for MPLS, add the MPLS compat code.

Bake in the SCTP states from the kernel UAPI. This means an older
revision of the kernel headers won't interfere with the SCTP display
enhancement. Additionally, if a newer version is available, or if
x-compiling the datapath module we defer to that version (since this
is just meant to provide the missing definitions).
This will be used in a future commit.

Added compatibility headers for actions vlan and tunnel key.
Do not use compat code when compiling kernel datapath
there is no need for it as TC compatibility is not provided there.
In other words, the compat code is only used when compiling user-space
code against old kernel headers.

Until now, the OVS source tree has had a whole maze of header files that
make "#include <linux/openvswitch.h>" work OK regardless of platform, but
this confuses everyone new to the tree, at first glance, and is difficult
to understand at second glance too.
This commit renames include/linux/openvswitch.h to
datapath/linux/compat/include/linux/openvswitch.h without other change,
then modifies the userspace build to generate a header that makes sense in
portable Open vSwitch userspace from that header.
It then removes all the remaining include/linux/* files since they are now
unused.

We want datapath-protocol.h to be acceptable as a Linux kernel header, so
it must use Linux kernel types and must not have references to Open vSwitch
symbols or header files. This commit primarily makes that change to
datapath-protocol.h.
At the same time, at least for now we also want datapath-protocol.h to be
usable on non-Linux platforms, so we need some kind of compatiblity. Thus,
this commit also introduces a <linux/types.h> header file that defines the
necessary Linux kernel types on non-Linux platforms.
In turn, this requires openvswitch/types.h to use the Linux types directly
for ovs_be<N>; otherwise, sparse complains because now __be<N> and
ovs_be<N> are incompatible from its perspective, so this commit makes that
change too.
I don't have a non-Linux kernel platform readily available, so I only
tested the non-Linux part of the linux/types.h substitute by forcing that
case to be triggered with #if 0. It worked, except for errors in actual
Linux kernel headers included explicitly from OVS source files, so I think
it's likely to work in practice.
Bug #7559.

Currently ovs is using device stats for Linux devices and count them
itself in other situations. This leads to overlap with hardware stats,
inconsistencies, etc. It's much better to just always count the packets
flowing through the switch and let userspace do any merging that it wants.
Following patch removes vport->get_stats() interface. vport-stat is changed
to use new `struct ovs_vport_stat` rather than rtnl_link_stats64.
Definitions of rtnl_link_stats64 is removed from OVS. dipf_port->stat is also
removed as aggregate stats are only available at netdev layer.
