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
