Better logging output. Added 'struct proto *' info 'struct ospf iface'.

addresses per interface (needed for example for IPv6 support).

Visible changes:

o  struct iface now contains a list of all interface addresses (represented
   by struct ifa), iface->addr points to the primary address (if any).
o  Interface has IF_UP set iff it's up and it has a primary address.
o  IF_UP is now independent on IF_IGNORED (i.e., you need to test IF_IGNORED
   in the protocols; I've added this, but please check).
o  The if_notify_change hook has been simplified (only one interface pointer
   etc.).
o  Introduced a ifa_notify_change hook. (For now, only the Direct protocol
   does use it -- it's wise to just listen to device routes in all other
   protocols.)
o  Removed IF_CHANGE_FLAGS notifier flag (it was meaningless anyway).
o  Updated all the code except netlink (I'll look at it tomorrow) to match
   the new semantics (please look at your code to ensure I did it right).

Things to fix:

o  Netlink.
o  Make krt-iface interpret "eth0:1"-type aliases as secondary addresses.

networks).

Removed old #ifndef logic which was used to avoid IPv4/IPv6 clashes
before conditionals in Modules lists were introduced.

Just changes of comments.

Hello timer implemented.

Work on hello continues.

gateway, and who told us, so they can do usefull jobs from now on.

Redesigned struct ospf_iface & new struct ospf_sock.

Small bug fix in memcpy.

and not ip_mreqn). This should get multicasts on unnumbered PtP links work.

o  ((flags & IF_CHANGE_UP) == IF_CHANGE_UP)   ->   (flags & IF_CHANGE_UP)
o  bcopy  ->  memcpy   (bcopy is unportable)
o  Ifdeffed out add_tail(&(ifa->sk_list),NODE mcsk) -- the node in socket
   structure is for internal use by the resource manager only. (Now, the
   debugging dump of open sockets looks sane :-)).

Added wait timer for eligible BCAST & NBMA interface.

Change in ospf_iface. (My bad understanding of lists manipulation.)

IPv6 changes.

possible to write if 1.2.3.4 < 1.2.3.5, but I'm not sure if it is good
for anything.)

Small change to stop using loopback.

A small init change to avoid core dump.

Not all I mean serious. Almost everything will change.
Changes: struct ospf_iface draft, various constants added...

compare function is ready.

operations on 2.1/2.2 kernels. This allows passing of real interface
indexes instead of referencing interfaces by their IP addresses which
fails badly in presence of unnumbered interfaces.

Unfortunately, this structure is not visible with glibc 2.0 as it provides
its own networking headers :-(  Both libc5 and glibc 2.1 should be OK.

See comments in lib/socket.h for a detailed guide on how to use them.

Also made "depend" work before the tree is compiled first time.
