creation of links with given index (if it's free, or course). This
functionality is available since linux-v3.5.
This patch makes this API available via ip tool.

Currently ip-link(8) parses, but ignores "group" argument to
peer interface on veth creation.
Insert IFLA_GROUP attribute for peer interface when present.

Based on patch by Sergey Popovich <popovich_sergei@mail.ru>
This fixes crash when ip-link(8) invoced with command:
ip link add dev veth1a type veth peer
Add the group keyword to ip link set, which has the following meaning:
If both a group and a device name are pressent, we change the device's
group to the specified one. If only a group is present, then the
operation specified by the rest of the command should apply on an entire
group, not a single device.
So, to set eth0 to the default group, one would use
ip link set dev eth0 group default
Conversely, to set all the devices in the default group down, use
ip link set group default down

Making veth a shared library for ip caused build problems (not PIC)
and is unneeded.

The usage is
# ip link add [name] type veth [peer <name>] [mac <mac>] [peer_mac <mac>]
This version doesn't include the fix for ip/iplink.c as Patrick
said that he had included it into his patches already.
