Previously if using rtnl_addr_set_prefixlen() the new prefix length
was not forwarded to the corresponding 'struct nl_addr' objects
associated with address already and thus the comparison function
would fail.
This patch also clears the internal ADDR_ATTR_PREFIXLEN flag if
the prefix length has been reset.

Introduces new unit tests based on `check`. Each subsystem/module can
have its own unit tests in tests/check-<name>.c that will be linked
together in tests/check-all.c.
Running 'make check' will compile and run the unit tests automatically.
A reference unit test implementation has been done for the abstract
address module.

Use a debugging message to warn applications if an attribute is
found multiple times in the same message. It is perfectly valid
to rely on this behaviour but it is likely to indicate a bug.

This patch fixes a bug where because of the af_ops check
being first in the function, we were returning ~0 if af_ops
was null even if both objects really did not have af_data
and we should be returning 0.
Its better to have the af_data present check before anything else.
So, Rearranged some of the code in rtnl_link_af_data_compare.
Changes include:
- Do the attribute present check before anything else
- If ao_compare op not present, return ~0

In the current code if rtnl_link_af_data_compare returns value > 0
we mark PROTINFO attribute in the diff mask and return without
comparing flags.
This patch makes af_data to be the last thing we compare.

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.

This check was introduces to not accidently return AF_BRIDGE objects
to unaware API users as they do differ in structure. However, such
objects are only available if explicitely requests using the
NL_CACHE_AF_ITER flag or by using arg1 == AF_BRIDGE for the cache.
Therefore remove this check and allow rtnl_neigh_get() to be used to
fetch any neighbor object of a cache.

This patch reverts back the AF_UNSPEC check introduced by AF_BRIDGE
changes at http://lists.infradead.org/pipermail/libnl/2012-November/000796.html
After the addition of AF_BRIDGE support, link cache can now contain objects of
type AF_BRIDGE. To make sure existing api's did not return AF_BRIDGE objects
and surprise existing callers, I introduced the check for AF_UNSPEC.
But from what Andy Wang reported, rtnl_link_get_by_name returns the first
link object with matching ifindex and that could have not only been AF_UNSPEC
but also of family AF_INET6. And his app always got an AF_INET6 object prior
to the patch that introduced the AF_UNSPEC check.
I could just add AF_INET6 family check along with AF_UNSPEC in the apis and that
should work well.
But thinking about it some more, removing the AF_UNSPEC change seems to be safer at
this point. That way this api will retain its semantics and return the first object
with matching ifindex. It could be of any supported family. The user will know if the
cache contains bridge objects, because they are available only with the cache flag
NL_CACHE_AF_ITER. Besides, if new users want to search for a specific object,
nl_cache_find is a better option.
