The iptables code supports a "no shared libs" mode where it can be used
without requiring dlfcn related functionality.  This adds similar support
to iproute2 so that it can easily be used on systems like nommu Linux (but
obviously with a few limitations -- no dynamic plugins).

Rather than modify every location that uses dlfcn.h, I hooked the dlfcn.h
header with stub functions when shared library support is disabled.  Then
symbol lookup is done via a local static lookup table (which is generated
automatically at build time) so that internal symbols can be found.

This patch adds support for configuring GRE tunnels using the
new rtnl_link interface.  This only works on kernels that have
the new GRE configuration interface.

This is accessed through the "ip link" command.  The previous
tunnel configuration interface "ip tunnel" remains as it is
and should be retained for compatibility with old kernels.

get_link_kind() fails for statically linked modules (vlan, veth, etc.) if "ip"
was linked without "export-dynamic".

Making veth a shared library for ip caused build problems (not PIC)
and is unneeded.
Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org>

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.

This is a resend of the iproute VLAN patch with the if_link.h changes
edited out since the headers are already synced.

Add support for using netlink for link configuration. Kernel-support is
probed, when not available it falls back to using ioctls.

The new command is called "veth" with the following syntax:
* ip veth add <dev1> <dev2>
  creates interconnected pair of veth devices.
* ip veth del <dev>
  destroys the pair of veth devices, where <dev> is either
  <dev1> or <dev2> used to create the pair.

One question that is to be solved is whether or not to create
a hard-coded netlink family for veth driver. Without it the
family resolution code has to be moved to general place in ip
utility (by now it is copy-paste-ed from one file to another
till final decision).

Fix ip6tunnel.c to be fit with current ip command style.
Unlike other modules currently iptunnel (and ip6tunnel) is not
designed as protocol-independent because of unarranged structure
between IPv4 and IPv6.

Usage: ip -f inet6 tunnel { add | change | del | show } [ NAME ]
          [ remote ADDR local ADDR ] [ dev PHYS_DEV ]
          [ encaplimit ELIM ]
          [ hoplimit HLIM ] [ tc TC ] [ fl FL ]
          [ dscp inherit ]

Where: NAME := STRING
       ADDR := IPV6_ADDRESS
       ELIM := { none | 0..255 }(default=4)
       HLIM := 0..255 (default=64)
       TC   := { 0x0..0xff | inherit }
       FL   := { 0x0..0xfffff | inherit }

Split common functions like ioctl to export them.
This is a preparation to support to configure IPv6-over-IPv6 tunnel.
This patch also includes minor improvemen:
 o to stop to include unused headers
 o to change function static if it is not needed to be exported
