OSPF: Redesign LSA checksumming
...
New LSA checksumming code separates generic Fletcher-16 and OSPF-specific
code and avoids back and forth endianity conversions, making it much more
readable and also several times faster.

OSPF: Fixes validation of LSA checksums
...
Prior to this patch, BIRD validates the OSPF LSA checksum by calculating
a new checksum and comparing it with the checksum in the header. Due to
the specifics of the Fletcher checksum used in OSPF, this is not
necessarily correct as the checkbytes in the header may be calculated via
a different means and end up with a different value that is nonetheless
still correct.
The documented means of validating the checksum as specified in RFC 905
B.4 is to calculate c0 and c1 from the unchanged contents of the packet,
which must result in a zero value to be considered valid.
Thanks to Chris Boot for the patch.

Vastly improved OSPF reconfiguration.
...
Now it can handle a change in iface pattern structure.
It can add, remove and reconfigure interfaces, vlinks and areas.

Huge OSPF database redesign. Since now, all LSAs of all areas
...
are in single database. This avoids duplication of external LSAs and
fixes bug in external LSA distribution.
