pointers are mapped read-only in the kernel image.

before adding it to the routing table. The rtable code is doing memcmp()
of those rt_dest sockaddrs so it is important that they are stored in a
canonical form. To do this struct domain is extended to include the
sockaddr size for this address family.

basic anyway. Simplifies the code a lot also by calling the mpls sysctl no
longer via the protosw but instead directly.
OK mpi@ on a previous diff. Also tested by renato@ who actually found a bug
which is now fixed.

route entry in ART.
rt_plen() now represents the prefix length of a route entry and should
be used instead.
For now use a "struct sockaddr_in6" to represent the mask when needed,
this should be then replaced by the prefix length and RTA_NETMASK only
used for compatibility with userland.

The routing table is not an optional component of the network stack
and initializing it inside the "routing domain" requires some ugly
introspection in the domain interface.
This put the rtable* layer at the same level of the if* level. These
two subsystem are organized around the two global data structure used
in the network stack:
- the global &ifnet list, to be used in process context only, and
- the routing table which can be read in interrupt context.
This change makes the rtable_* layer domain-aware and extends the
"struct domain" such that INET, INET6 and MPLS can specify the length
of the binary key used in lookups. This allows us to keep, or move
towards, AF-free route and rtable layers.
While here stop the madness and pass the size of the maximum key length
in *byte* to rn_inithead0().

length of the key as argument.
This way every consumer of the radix tree has a chance to explicitly
initialize the shared data structures and no longer rely on another
subsystem to do the initialization.
As a bonus ``dom_maxrtkey'' is no longer used an die.
ART kernels should now be fully usable because pf(4) and IPSEC properly
initialized the radix tree.

As a side effect there's no need to run if_attachdomain() after the
list of domains has been built.

Code abusing the radix internals for the routing table should now
includes <net/rtable.h> and only deal with "struct rtentry".
Code using a radix tree for another purpose can still include
<net/radix.h>.

the priority support that comes together with it. Currently no balancing
will happen, only the first path will be used.

Now it contains just the label as it must be.
This introduces a ugly hack in rtentry that will be removed
as soon as possible.

Remove smpls_in_iface as labels must be per platform unique.
Remove smpls_out_iface. It is redudant and can be inferred from nexthop.
Move smpls_operation to rt_flags and temporary remove smpls_out_exp.

Fix my faulty import....

MPLS support partly based on the (abandoned?) AYAME project.
Basic LSR (Label Switch Router) functionality is present, but not fully
functional yet.
It is currently possible to insert entries in the LIB (Label Information Base)
with route(8), but setting the operation type is not supported yet.
Imported to allow more people to work on this in the coming weeks.
