RIP sockets for multiple ifaces collided, because we cannot bind to
a specific iface on BSD. Workarounded by SO_REUSEPORT.

Thanks to Eugene M. Zheganin for the bugreport.

Inspired by the patch from Alexander V. Chernikov.

Remove support for historic Linux kernels,
merge krt-iface, krt-set and krt-scan stub headers.

- BSD kernel syncer is now self-conscious and can learn alien routes
- important bugfix in BSD kernel syncer (crash after protocol restart)
- many minor changes and bugfixes in kernel syncers and neighbor cache
- direct protocol does not generate host and link local routes
- min_scope check is removed, all routes have SCOPE_UNIVERSE by default
- also fixes some remaining compiler warnings

BSD hates it, Linux needs it.

multicast abilities depending on definedness of symbols and use hard-wired
system-dependent configuration defines instead.

Please test whereever you can.

to distinguish between our own routes and alien ones.

documented the remaining ones (sysdep/cf/README).

Available configurations:

   o  linux-20: Old Linux interface via /proc/net/route (selected by default
		on pre-2.1 kernels).
   o  linux-21: Old Linux interface, but device routes handled by the
		kernel (selected by default for 2.1 and newer kernels).
   o  linux-22: Linux with Netlink (I play with it a lot yet, so it isn't
		a default).
   o  linux-ipv6: Prototype config for IPv6 on Linux. Not functional yet.

but the framework is there and I'll try finish it soon.

CONFIG_ALL_MULTICAST (all interfaces capable of multicasting, not depending
on IFF_MULTICAST flag).

by the `mergedirs' script. Few more IP address manipulation functions
and some fixes.
