757cab18d6 BGP: Support for MD5SIG together with remote range
When dynamic BGP with remote range is configured, MD5SIG needs to use
newer socket option (TCP_MD5SIG_EXT) to specify remote addres range for
listening socket.

Thanks to Adam Kułagowski for the suggestion.

cc75b3e1dc KRT: Remove KRF_SYNC_ERROR flag
This info is now stored in an internal bmap. Unfortunately, net.flags
is still needed for temporary kernel data.

a1ee5eb2aa BSD: Fix TCP-MD5 code on current FreeBSD kernels
Current FreeBSD kernels require SA records for both directions.

Thanks to Joseph Mulloy and Andrey V. Elsukov for reporting and
solving the issue.

318acb0f6c BSD: Use MSG_DONTROUTE for unicast packets on FreeBSD
BSD systems cannot use SO_DONTROUTE, because it does not work properly
with multicast packets (perhaps it tries to find iface based on multicast
group address). But we can use MSG_DONTROUTE sendmsg() flag for unicast
packets. Works on FreeBSD, is ignored on OpenBSD and is broken on NetBSD
(i guess due to integrated routing table and ARP table).

13c0be19d3 Nest: Removing separate tmpa from route propagation
This is a fundamental change of an original (1999) concept of route
processing inside BIRD. During import/export, there was a temporary
ea_list created which was to be used instead of the another one inside
the route itself.

This led to some confusion, quirks, and strange filter code that handled
extended route attributes. Dropping it now.

The protocol interface has changed in an uniform way -- the
`struct ea_list *attrs` argument has been removed from store_tmp_attrs(),
import_control(), rt_notify() and get_route_info().

4d36796131 KRT: Fix direct routes for BSD
Old way to set direct routes is to use local IP as gateway, but that does
not work properly on newer FreeBSDs. Now we use sockaddr_dl containing
interface index as gateway.

4e276a8920 Merged multipath and single-path data structures.
Dropped struct mpnh and mpnh_*()
Now struct nexthop exists, nexthop_*(), and also included struct nexthop
into struct rta.

Also converted RTD_DEVICE and RTD_ROUTER to RTD_UNICAST. If it is needed
to distinguish between these two cases, RTD_DEVICE is equivalent to
IPA_ZERO(a->nh.gw), RTD_ROUTER is then IPA_NONZERO(a->nh.gw).

From now on, we also explicitely want C99 compatible compiler. We assume
that this 20-year norm should be known almost everywhere.

e86cfd41d9 KRT: Fix route learn scan when route changed
When a kernel route changed, function krt_learn_scan() noticed that and
replaced the route in internal kernel FIB, but after that, function
krt_learn_prune() failed to propagate the new route to the nest, because
it confused the new route with the (removed) old best route and decided
that the best route did not changed.

Wow, the original code (and the bug) is almost 17 years old.

9ddbfbddf8 Netlink: Allow more than 256 routing tables.

allow 32-bit routing table IDs. Using this attribute to index routing
tables at Linux, instead of 8-bit rtm_table field.
