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 ;-)

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.
