Early merge of upstream headers

BEFORE:
              The show command has additional formatting options:

       -s, -stats, -statistics
              output more statistics about packet usage.

       -d, -details
              output more detailed information.

       -h, -human, -human-readble
              output statistics with human readable values number followed by suffix

       -iec   print human readable rates in IEC units (ie. 1K = 1024).

When output the netlink sockets:

    ss -A netlink state close

the layout is a little broken with a shifted 'Peer Address:Port'
stars and empty new lines. Fixed by making the port field to be
wider for 'Local Address:Port' column.

I dont see a reason that packet and netlink states will be
printed only if SS_CLOSE state is set in filter, in that case
to print states of netlink or packet sockets it is needed to run:

    ss -A netlink state close

instead of:

    ss -A netlink

As 'ip' util will share the same netns from the caller
process then we can just look at /proc/self/.. to show
the netns of the current process by:

    ip netns id

There were only few Netlink protocol names
which were printed on the screen:

Man pages for Foo-over-UDP and Generic UDP Encapsulation receive
port configuration. gue man page links to fou one.
Signed-off-by: Tom Herbert <therbert@google.com>

This patch adds support to configure foo-over-udp (FOU) and Generic
UDP Encapsulation for GRE tunnels. This configuration allows selection
of FOU or GUE for the tunnel, specification of the source and
destination ports for UDP tunnel, and enabling TX checksum. This
configuration only affects the transmit side of a tunnel.

Example:

ip link add name tun1 type gre remote 192.168.1.1 local 192.168.1.2 \
   ttl 225 encap fou encap-sport auto encap-dport 7777 encap-csum

This would create an GRE tunnel in GUE encapsulation where the source
port is automatically selected (based on hash of inner packet) and
checksums in the encapsulating UDP header are enabled.

Added 'ip fou...' commands to enable/disable UDP ports for doing
foo-over-udp and Generic UDP Encapsulation variant. Arguments are port
number to bind to and IP protocol to map to port (for direct FOU).

Examples:

ip fou add port 7777 gue
ip fou add port 8888 ipproto 4

The first command creates a GUE port, the second creates a direct FOU
port for IPIP (receive payload is a assumed to be an IPv4 packet).

Width is the maximum number of characters used for the value, excluding a
field separator. So append a single whitespace.

Add a new -iec option in addition to -human.
Cleanup code so the formatting of numbers is done in one function,
not 2 ways and 2 sizes.

Byte and packet count can increase to really big numbers. This adds a
switch to show human readable output.

- any ipv6 tunnel mode (proto == 0) could not be set
due to incomplete set of cases in do_add, do_del.
- vti6 logic was inverted: it was using "ip6_vti0" basedev
UNLESS mode is set to vti6.

We don't need a switch by p.proto in do_add()/do_del(): it
already exists in parse_args(). So if parse_args() call
was successful, no need to check tunnel mode again.

Such approach allows to run *.t scripts from any
tests/ subdirectories.

One point is that tests from tests/cls/*.t (which are needed
by tests/cls-testbed.t but does not exist yet) will also
be ran aside with tests/cls-testbed.t which is not good
because in such case they will be ran twice, so renamed these
tests path to tests/cls/*.c in tests/cls-testbed.t
