8ecbaf9c70 Fixes a bug with neighbor cache and overlapping IP prefixes.
When there are overlapping IP prefixes and one disappears,
neighbors associated with it was removed even if there
is another covering IP prefix.

69a8259c5e Allows sticky link-local neighbors.
Allows using NEF_STICKY neighbors with link-local addresses. This is
used for static route nexthops, they can be specified like fe80::1%eth0
.

52a43ae3b7 Minor changes in addresses.
Mainly changes IA_UNNUMBERED to IA_PEER and adds IA_HOST. Also do not
show broadcast addr in show interfaces. Nobody cares for that.

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

d6a836f8d6 Fixes core state machine.
The core state machine was broken - it didn't free resources
in START -> DOWN transition and might freed resources after
UP -> STOP transition before protocol turned down. It leads
to deadlock on olock acquisition when lock was not freed
during previous stop.

The current behavior is that resources, allocated during
DOWN -> * transition, are freed in * -> DOWN transition,
and flushing (scheduled in UP -> *) just counteract
feeding (scheduled in * -> UP). Protocol fell down
when both flushing is done (if needed) and protocol
reports DOWN.

BTW, is thera a reason why neighbour cache item acquired
by protocol is not tracked by resource mechanism?

0f32f2a65a Modified the neighbor cache to remember local addresses as well.
neighbor->scope now contains proper address scope which is zero (SCOPE_HOST)
for local addresses, higher (SCOPE_LINK, ..., SCOPE_UNIVERSE) for remote ones.

200accf396 if_connected() is again private.
Introduced neigh_connected_to() to serve the same purpose efficiently.

6b9fa32080 Great cleanup of debug messages. LOCAL_DEBUG turned off in most modules,
several debug() calls converted to DBG().
