1e37e35c3e BGP: Support for MPLS labels and VPN SAFI
Basic support for SAFI 4 and 128 (MPLS labeled IP and VPN) for IPv4 and
IPv6. Should work for route reflector, but does not properly handle
originating routes with next hop self.

Based on patches from Jan Matejka.

a5d2a34497 Minor cleanups
BTW, 'prefices' is hypercorrection, as 'prefix' is from 'praefixum' with
plural 'praefixa'.

7a855725f2 Some autoconf cleanups
The patch allows to use autoreconf, replaces some long obsolete
constructs and does some other minor cleanups. Also, the file
configure.in is renamed to configure.ac, as the old name has been
deprecated for a long time.

Thanks to Ruben Kerkhof for the patchset.

This may be useful if multple interfaces share the same network range.

27f6ba651e BGP: Fix bug in ADD_PATH
When a BGP session with ADD_PATH is restarted and the neighbor do not
announce ADD_PATH capability during reconnect, the accept_ra_types is
still set to RA_ANY.

7126cadf80 Static: Minor overhaul
The patch fixes several bugs introduced in previous changes, simplifies
the protocol by handing routes uniformly, introduces asynchronous route
processing to avoid issues with separate notifications for each next-hop
in ECMP routes, and makes reconfiguration faster by avoiding quadratic
complexity.

93f50ca317 Nest: names for nhu_state values
It took too much time to analyze what's the meaning of nhu_state values
so I spent less than the same amount of time documenting it.

30c734fc73 Static: Fix bug in static route filter expressions
During reconfiguration, old and new filter expressions in static routes
are compared using i_same() function. When filter expressions contain
function calls, it is necessary that old filter expressions are the
second argument in i_same(), as it is internally modified by i_same().
Otherwise pointers to old (and freed) data appear in the config
structure.

Thanks to Lennert Buytenhek for tracking and reporting the bug.

d311368bc5 VPN4 and VPN6 literals
From now on, protocol static accepts VPN4 and VPN6 addressess.
With some concerns about VPN6 Route Distinguishers, I finally chose
to have the same format as for VPN4 (where it is defined by RFC 4364).

d14f8c3c45 Netlink: MPLS routes in kernel
Anyway, Bird is now capable to insert both MPLS routes and MPLS encap
routes into kernel.

It was (among others) needed to define platform-specific AF_MPLS to 28
as this constant has been assigned in the linux kernel.

No support for BSD now, it may be added in the future.

4e276a8920 Merged multipath and single-path data structures.
Dropped struct mpnh and mpnh_*()
Now struct nexthop exists, nexthop_*(), and also included struct nexthop
into struct rta.

Also converted RTD_DEVICE and RTD_ROUTER to RTD_UNICAST. If it is needed
to distinguish between these two cases, RTD_DEVICE is equivalent to
IPA_ZERO(a->nh.gw), RTD_ROUTER is then IPA_NONZERO(a->nh.gw).

From now on, we also explicitely want C99 compatible compiler. We assume
that this 20-year norm should be known almost everywhere.

Stubnet nodes in OSPF FIB were removed during rt_sync(), but the pointer

confused, reported 'LSA ID collision' and net-summary LSAs were not
originated properly.
