1a2ad348f6 OSPF: Support for graceful restart
Implement OSPFv2 (RFC 3623) and OSPFv3 (RFC 5187) graceful restart,
for both restarting and helper sides. Graceful restart is initiated
by 'graceful down' command.

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.

9e7d3a7810 OSPF: Fix net-summary origination combined with stubnet option
Stubnet nodes in OSPF FIB were removed during rt_sync(), but the pointer
remained in top_hash_entry.nf, so net-summary LSA origination was
confused, reported 'LSA ID collision' and net-summary LSAs were not
originated properly.

Thanks to Naveen Chowdary Yerramneni for bugreport and analysis.

fe9f1a6ded Initial commit on integrated BIRD
New data types net_addr and variants (in lib/net.h) describing
network addresses (prefix/pxlen). Modifications of FIB structures
to handle these data types and changing everything to use these
data types instead of prefix/pxlen pairs where possible.

The commit is WiP, some protocols are not yet updated (BGP, Kernel),
and the code contains some temporary scaffolding.

Comments are welcome.

145368f547 Extends multipath support for OSPF.
Fixes cases where the same network or external route are propagated by
several OSPF routes and some other corner cases in next hop construction
and ECMP. Allows to specify whether external routes should be merged.

Thanks to Peter Christensen for the original patch.

e0a62ad0f8 Fixes a bug in duplicit configured stubnets.
If there was the same configured stubnet on local and remote
router, the remote route always won regardless of its cost.

c27b2449d1 Shows source (Router ID) for OSPF routes and adds such attribute.
A sad thing is that we does not have a 'router_id' filter type,
so it must be given as decimal number in filters.

98ac61766d A lot of changes:
- metric is 3 byte long now
	- summary lsa originating
	- more OSPF areas possible
	- virtual links
	- better E1/E2 routes handling
	- some bug fixes..

I have to do:
	- md5 auth (last mandatory item from rfc2328)
	- !!!!DEBUG!!!!! (mainly virtual link system has probably a lot of bugs)
	- 2328 appendig E
