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.

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).

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.

- summary lsa originating
- more OSPF areas possible
- virtual links
- better E1/E2 routes handling
- some bug fixes..

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