3e236955c9 Build: switch on -Wextra, get rid of most of the warnings
There are several unresolved -Wmissing-field-initializers on older
versions of GCC than 5.1, all of them false positive.

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.
Since 2.6.19, the netlink API defines RTA_TABLE routing attribute to
allow 32-bit routing table IDs. Using this attribute to index routing
tables at Linux, instead of 8-bit rtm_table field.

f515e22924 Allows other than IA_PEER addresses on PtP ifaces on BSD.
Also fixes a potential problem with link-local dest_addrs
for IA_PEER addresses.

Thanks to Alexander V. Chernikov for the suggestion.

094d2bdb79 Implements ADD-PATH extension for BGP.
Allows to send and receive multiple routes for one network by one BGP
session. Also contains necessary core changes to support this (routing
tables accepting several routes for one network from one protocol).
It needs some more cleanup before merging to the master branch.

396dfa9042 Cleanup in sysdep KRT code, part 1.
OS-dependent functions renamed to be more consistent,
prepared to merge krt-set and krt-scan headers.

Name changes:

struct krt_if_params -> struct kif_params
struct krt_if_status -> struct kif_status
struct krt_set/scan_params -> struct krt_params
struct krt_set/scan_status -> struct krt_status

krt_if_params_same -> kif_sys_reconfigure
krt_if_copy_params -> kif_sys_copy_config
krt_set/scan_params_same -> krt_sys_reconfigure
krt_set/scan_copy_params -> krt_sys_copy_config

krt_if_scan -> kif_do_scan
krt_set_notify -> krt_do_notify
krt_scan_fire -> krt_do_scan

krt_if_ -> kif_sys_
krt_scan_ -> krt_sys_

cfe34a316e Implements hostcache and recursive next hops.
Hostcache is a structure for monitoring changes in a routing table that
is used for routes with dynamic/recursive next hops. This is needed for
proper iBGP next hop handling.

c429d4a4ba Restrict export of device routes to the kernel protocol.
In usual configuration, such export is already restricted
with the aid of the direct protocol but there are some
races that can circumvent it. This makes it harder to
break kernel device routes. Also adds an option to
disable this restriction.

ff2857b03d Many changes in (mainly) kernel syncers.
- 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
