IPVLAN and IPVTAP are using the same functions and parameters. So we can
just add a new link_util with id ipvtap. Others are the same.

IPvlan supported bridge-only functionality prior to commits
a190d04db937 ('ipvlan: introduce 'private' attribute for all
existing modes.') and fe89aa6b250c ('ipvlan: implement VEPA mode').
These two commits allow to configure the VEPA and private modes now.
This patch adds those options in ip command.
e.g.
bash:~# ip link add link eth0 name ipvl0 type ipvlan mode l2 private
-or-
bash:~# ip link add link eth0 type ipvl0 type ipvlan mode l2 vepa
Also the output will reflect the mode and the mode-flag accordingly.
e.g.
bash:~# ip -details link show ipvl0
4: ipvl0@eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc ...
link/ether 00:1a:11:44:a5:3e brd ff:ff:ff:ff:ff:ff promiscuity 0
ipvlan mode l2 private addrgenmode eui64 numtxqueues 1 ...

The new mode 'l3s' can be set like -
ip link add link <master> dev <IPvlan-slave> type ipvlan mode l3s
e.g. ip link add link eth0 dev ipvl0 type ipvlan mode l3s
Also did some trivial code restructuring.

Adding basic support to create virtual devices using 'ip'
utility. Following is the syntax -
ip link add link <master> <virtual> type ipvlan mode [ l2 | l3 ]
e.g. ip link add link eth0 ipvl0 type ipvlan mode l3
