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.
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.
