This patch is to add LWTUNNEL_IP(6)_OPTS and LWTUNNEL_IP_OPTS_GENEVE's
parse and print to implement geneve options support in iproute_lwtunnel.
Options are expressed as class:type:data and multiple options may be
listed using a comma delimiter, class and type are numbers and data
is a hex string.
With this patch, users can add and dump geneve options like:
# ip netns add a
# ip netns add b
# ip -n a link add eth0 type veth peer name eth0 netns b
# ip -n a link set eth0 up; ip -n b link set eth0 up
# ip -n a addr add 10.1.0.1/24 dev eth0
# ip -n b addr add 10.1.0.2/24 dev eth0
# ip -n b link add geneve1 type geneve id 1 remote 10.1.0.1 ttl 64
# ip -n b addr add 1.1.1.1/24 dev geneve1
# ip -n b link set geneve1 up
# ip -n b route add 2.1.1.0/24 dev geneve1
# ip -n a link add geneve1 type geneve external
# ip -n a addr add 2.1.1.1/24 dev geneve1
# ip -n a link set geneve1 up
# ip -n a route add 1.1.1.0/24 encap ip id 1 geneve_opts \
1:1:1212121234567890,1:1:1212121234567890,1:1:1212121234567890 \
dst 10.1.0.2 dev geneve1
# ip -n a route show
# ip netns exec a ping 1.1.1.1 -c 1
1.1.1.0/24 encap ip id 1 src 0.0.0.0 dst 10.1.0.2 ttl 0 tos 0
geneve_opts 1:1:1212121234567890,1:1:1212121234567890 ...
PING 1.1.1.1 (1.1.1.1) 56(84) bytes of data.
64 bytes from 1.1.1.1: icmp_seq=1 ttl=64 time=0.079 ms
v1->v2:
- improve the changelog.
- use PRINT_ANY to support dumping with json format.
v2->v3:
- implement proper JSON array for opts instead of just bunch of strings.
v3->v4:
- keep the same format between input and output, json and non json.
- print class and type as uint and print data as hex string.

How to compile this.
--------------------
1. libdbm
arpd needs to have the berkeleydb development libraries. For Debian
users this is the package with a name like libdbX.X-dev.
DBM_INCLUDE points to the directory with db_185.h which
is the include file used by arpd to get to the old format Berkeley
database routines. Often this is in the db-devel package.
2. make
The makefile will automatically build a config.mk file which
contains definitions of libraries that may or may not be available
on the system such as: ATM, ELF, MNL, and SELINUX.
3. To make documentation, cd to doc/ directory , then
look at start of Makefile and set correct values for
PAGESIZE=a4 , ie: a4 , letter ... (string)
PAGESPERPAGE=2 , ie: 1 , 2 ... (numeric)
and make there. It assumes, that latex, dvips and psnup
are in your path.
4. This package includes matching sanitized kernel headers because
the build environment may not have up to date versions. See Makefile
if you have special requirements and need to point at different
kernel include files.
