Since almost every UNIX system requires different techniques for reading the kernel routing table as opposed to modifying it which is approximately the same on non-netlink systems, I've split the kernel routing table routines to read and write parts. To be implemented later ;-)

Hopefully finished kernel syncer (krt) rewrite: 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.

KRF_* flags moved to krt.h as they are internal to kernel syncer, fib->pad0,pad1 renamed to x0,x1 and in case of struct net x0 is reserved for kernel syncing as well.

/* Flags stored in net->n.flags */
Rewritten kernel syncer. Now uses the rta trickery I've introduced yesterday and does things "the right way". Few things are still missing (device routes etc.), I'll add them later in the evening.

Kernel syncer is now configurable. It will probably need some more options, but at least basic tuning is possible now.
