should work now. Initial feeding of protocols by interfaces/routes is
done from the event queue to prevent unwanted recursion.

of various callbacks.
Events are just another resource type objects (thus automatically freed
and unlinked when the protocol using them shuts down). Each event can
be linked in at most one event list. For most purposes, just use the
global event list handled by the following functions:
ev_schedule Schedule event to be called at the next event
scheduling point. If the event was already
scheduled, it's just re-linked to the end of the list.
ev_postpone Postpone an already scheduled event, so that it
won't get called. Postponed events can be scheduled
again by ev_schedule().
You can also create custom event lists to build your own synchronization
primitives. Just use:
ev_init_list to initialize an event list
ev_enqueue to schedule event on specified event list
ev_postpone works as well for custom lists
ev_run_list to run all events on your custom list
ev_run to run a specific event and dequeue it

Introduced bug() which is like die(), but with level L_BUG. Protocols
should _never_ call die() as it should be used only during initialization
and on irrecoverable catastrophic events like out of memory.
Also introduced ASSERT() which behaves like normal assert(), but it calls
bug() when assertion fails. When !defined(DEBUGGING), it gets ignored.

o Interface syncing is now a part of krt and it can have configurable
parameters. Actually, the only one is scan rate now :)
o Kernel routing table syncing is now synchronized with interface
syncing (we need the most recent version of the interface list
to prevent lots of routes to non-existent destinations from
appearing). Instead of its own timer, we just check if it's
route scan time after each iface list scan.
o Syncing of device routes implemented.
o CONFIG_AUTO_ROUTES should control syncing of automatic device routes.
o Rewrote krt_remove_route() to really remove routes :)
o Better diagnostics.
o Fixed a couple of bugs.

when their destination comes on/off link. Deserves better testing :)
See example in bird.conf.

intended to serve as an example of interface pattern list use. As a side
effect, you can disable generating of device routes by disabling
this protocol.

user-defined numeric symbols. Whenever possible, use `expr' instead
of `NUM' to get full express ion power :-)

this happens, don't reject the whole interface, just mark it as index 0.
o Removed Pavel's comment about EFAULT and SIGSEGV. EFAULT is a valid return
code for cases where the buffer is too small.
o Commented out the smart interface list size logic temporarily as it seems
Linux 2.0 SIOCGIFCONF doesn't react to ifc_req==NULL sanely. Replaced it
by exponential stepping.

%I IP address
%#I IP address in hexadecimal

interface since it makes much trouble everywhere. Instead, we understand
secondary addresses as subinterfaces.
- In case interface addresses or basic flags change, we simply convert it
to a down/up sequence.
- Implemented the universal neighbour cache. (Just forget what did previous
includes say of neighbour caching, this one is brand new.)
