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.

/*
Rewrote the kernel syncer. The old layering was horrible. The new kernel syncer is cleanly split between generic UNIX module and OS dependent submodules: - krt.c (the generic part) - krt-iface (low-level functions for interface handling) - krt-scan (low-level functions for routing table scanning) - krt-set (low-level functions for setting of kernel routes) krt-set and krt-iface are common for all BSD-like Unices, krt-scan is heavily system dependent (most Unices require /dev/kmem parsing, Linux uses /proc), Netlink substitues all three modules. We expect each UNIX port supports kernel routing table scanning, kernel interface table scanning, kernel route manipulation and possibly also asynchronous event notifications (new route, interface state change; not implemented yet) and build the KRT protocol on the top of these primitive operations.

extern int if_scan_sock;
Implements protocol templates. Based on the patch from Alexander V. Chernikov. Extended to support almost all protocols. Uses 'protocol bgp NAME from TEMPLATE { ... }' syntax.
