0ea8fb4abe Fixes and enhancements in 'show ospf state' command. 
Now it shows a distance, option to change showing reachable/all network
nodes and better handling of AS-external LSAs in multiple areas. The
command 'show ospf topology' was changed to not show stubnets in both
OSPFv2 and OSPFv3 (previously it displayed stubnets in OSPFv2).

7969ea3b41 Fixes a bug in OSPF on NBMA interfaces. 
A very tricky bug. OSPF on NBMA interfaces probably never really worked.
When a packet was sent to multiple destinations, the checksum was
calculated multiple times from a packet with already filled checksum
field (from previous calculation). Therefore, many packets were sent
with an invalid checksum.

- important bugfix in BSD kernel syncer (crash after protocol restart)
- many minor changes and bugfixes in kernel syncers and neighbor cache
- direct protocol does not generate host and link local routes
- min_scope check is removed, all routes have SCOPE_UNIVERSE by default
- also fixes some remaining compiler warnings

dca75fd7c2 Removes phantom protocol from the pipe design. 
It seems that by adding one pipe-specific exception to route
announcement code and by adding one argument to rt_notify() callback i
could completely eliminate the need for the phantom protocol instance
and therefore make the code more straightforward. It will also fix some
minor bugs (like ignoring debug flag changes from the command line).

A sad thing is that we does not have a 'router_id' filter type,
so it must be given as decimal number in filters.

20e94fb85b A change in OSPF and RIP interface patterns.

more interface patterns with different 'options' sections:

024c310b53 Fixes broken cryptographic authentication in OSPF 
Cryptographic authentication in OSPF is defective by
design - there might be several packets independently
sent to the network (for example HELLO, LSUPD and LSACK)
where they might be reordered and that causes crypt.
sequence number error.

That can be workarounded by not incresing sequence number
too often. Now we update it only when last packet was sent
before at least one second. This can constitute a risk of
replay attacks, but RFC supposes something similar (like time
in seconds used as CSN).

b722fe7ebd Fixes bug in OSPF packet retransmission. 
If a DBDES packet from a master to a slave is lost, then the old code

databases.

When OSPF neighbor state drops down to EXSTART,
clear LSA request and retransmit lists, as specified

between EXSTART and LOADING states, which sometimes
happened.

It also contains related fix from Yury Shevchuk that
properly resets DB summary list iterator.

b21f68b4cd Fix bugs in OSPF MD5 authentication. First bug is that default 
values for MD5 password ID changed during reconfigure, Second
bug is that BIRD chooses password in first-fit manner, but RFC
says that it should use the one with the latest generate-from.

It also modifies the syntax for multiple passwords.
Now it is possible to just add more 'password' statements
to the interface section and it is not needed to use
'passwords' section. Old syntax can be used too.

a3b70dc499 Two new informative CLI commands for OSPF. 
Two new CLI commands for OSPF giving nice informative (and still machine
parsable) representation of OSPF network graph (based on datas from the
LSA database).

The first command (show ospf topology) shows routers, networks and stub
networks, The second command (show ospf state) shows also external
routes and area-external networks and routers propagated by given area
boundary router.

a97122a3ca Bugfix in LSA origination for PTP OSPF links. 
The code generating LSAs for PTP OSPF links is buggy. The old behavior
is that it generates PTP link if there is a full/ptp neighbor and stub
link if there isn't. According to RFC 2328, the correct behavior is to
generate stub link in both cases (in the first case together with PTP
link).

And because of buggy detection of unnumbered networks, for numbered
networks the code creates stub links with 0.0.0.0/32.
