Taken from upstream kernel commit bfe01a5ba2490f299e1d2d5508cbbbadd897bbe9

When we test idiag on 3.4 kernel, we always get ERANGE.
This is because libnl has its own copy for SK_MEMINFO_*,
which is actually newer than 3.4, where SK_MEMINFO_VARS
is larger than kernel's.
We add a copy from latest kernel, so on older kernel
libnl should still compile. Note, for kernel < 3.6
we don't have SK_MEMINFO_BACKLOG, we have to relax
the minlen.
'sock_diag.h' comes from v3.17 kernel sources
(bfe01a5ba2490f299e1d2d5508cbbbadd897bbe9), file
'include/uapi/linux/sock_diag.h'.

libnl3 contains a private copy of some kernel header files.
Normally, users are expected to install libnl and specify
-I$PREFIX/include/libnl3 as include path. As the private kernel
header files are not installed, this works fine.
However, it can be convenient to build against the libnl source
directory, without installing libnl. In this case, the private kernel
header files shaddow the system provided ones. This is undesired.
Move these files to a different directory to avoid this clash.

It can easily happen that the generated local netlink port is alrady in
use. In that case bind will fail with ADDRINUSE.
Users of libnl3 could workaround this, by managing the local ports
themselves, but sometimes these users are libraries too and they also
don't know which ports might be used by other components.
This patch changes that nl_socket_alloc() no longer initilizes the local
port id immediately. Instead it will be initialized when the user calls
nl_socket_get_local_port() the first time and thereby shows interest in
the value.
If bind() fails with ADDRINUSE, check if the user ever cared about the
local port, i.e. whether the local port is still unset. If it is still
unset, assume that libnl should choose a suitable port and retry until
an unused port can be found.

libnl used 'inetdevice.h' for the IPV4_DEVCONF_* names, which the kernel
in the meantime moved to public user space API and are now defined in 'ip.h'.
As a first step, rename the file 'inetdevice.h'.

- Inet diag allows users to gather low-level socket information.
- This library provides a higher-level API for creating inetdiag requests (via
idiagnl_connect and idiagnl_send_simple) and parsing the replies (via
idiagnl_msg_parse). A cache is also provided (via idiagnl_msg_alloc_cache).
- Request and message objects provide APIs for accessing and setting the
various properties of each.
- This library also allows the user to parse the inetdiag response attributes
which contain information about traffic class, TOS, congestion, socket
memory info, and more depending on the kernel version used.
- Includes doxygen documentation.
This provides support for the new bridging attributes provided
in IFLA_PROTINFO while maintaining backwards compatibility
with older kernels.
A set of new API functions are exported to access the bridging
information. rtnl_link_bridge_has_ext_info() can be used to
check whether a bridge object has been constructed based on
the newly available attributes or the old message format.

Some projects seem to have mistakenly included the private
API headers without actually needing them.
Provide dummy headers referring to the real headers to
provide backwards compatibility.

Various header files providing an API to implement own cache and
object types or implement link types have been available in the
past. Their API is marked unstable in the documentation and nobody
is using them so far.
Technically they have been causing ABI breakages in at least two
3.2.x releases. In order to avoid future accidental breakage, no
longer install these and require module developers to clone the
git tree and build modules off the git tree directly to make sure
that the API is unstable at this point.

The header has not been included in the headers list so it has been
been distributed in the tarball making it fail to build in old kernels.

The plug qdisc supports two operations - plug and unplug. When the
qdisc receives a plug ("buffer") command via netlink request,
packets arriving henceforth are buffered until a corresponding unplug
command is received. Depending on the type of unplug ("release_one"
or "release_indefinite"), the queue can be unplugged indefinitely or
selectively.
The plug qdisc allows a user to implement network output buffering
(aka output commit), used commonly in checkpoint based fault tolerance
systems. It also supports a general purpose queue plug/unplug
functionality.
The associated kernel module is available in David Miller's net-next
tree, commit: c3059be16c9ef29c05f0876a9df5fea21f29724f
This patch introduces userspace tools and API, to control the qdisc
via netlink messages.

This allows for multiple major versions to be installed in parallel. Pkg-config
files are adapted to provide appropriate cflags to find new header locations.
This commit adds some missing files (some header files, the files below
/etc and the bison/flex files) to the distribution tarball to ensure
that libnl can be built from the tarballs created using "make dist".
It also adds some incantations to properly generate the flex and bison
output since the generated output is no longer shipped in the tarball.
Finally got rid of all the qdisc/class/cls code duplication in
the tc module API. The API takes care of allocation/freeing the
tc object specific data.
I hope I got it right this time.
Issues solved:
* PACKAGE_VERSION was abused for SOVERSION
* unneeded DEP stage
* did not support out-of-tree builds
* no way to turn off silent mode
* overriding CFLAGS at make time was not supported
* no static libs were provided
