dccee40826 OSPF: variable-length array of size 0 replaced by alloca()'d pointer 
NULL pointer is safer than a random pointer onto stack if this function
gets changed and eventually broken.

17de3a023f BGP: Fix handling of strange IPv6 link-local-only next hops 
There are three common ways how to encode IPv6 link-local-only next hops:
(:: ll), (ll), and (ll ll). We use the first one but we should accept all
three. The patch fixes handling of the last one.

Thanks to Sebastian Hahn for the bugreport.

78e4a123bb BGP: Handle flowspec rules without dst part 
The RFC 5575 does not explicitly reject flowspec rules without dst part,
it just requires dst part in validation procedure for feasibility, which
we do not implement anyway. Thus flow without dst prefix is syntactically
valid, but unfeasible (if feasibilty testing is done).

Thanks to Alex D. for the bugreport.

newer socket option (TCP_MD5SIG_EXT) to specify remote addres range for
listening socket.

7d767c5a3d KRT: Improve syncer code to avoid using temporary data in rtable 
The old code stored route verdicts and temporary routes directly in
rtable. The new code do not store received routes (it immediately
compares them with exported routes and resolves conflicts) and uses
internal bitmap to keep track of which routes were received and which
needs to be reinstalled.

By not putting 'invalid' temporary routes to rtable, we keep rtable
in consistent state, therefore scan no longer needs to be atomic
operation and could be splitted to multiple events.

4ab54f1aef Nest: Fix bitmap cleanup 
Channel currently does not have independent pool and uses protocol pool,
which is freed when protocol changes state to down, while channel is
still in flushing. Move some some cleanup code to channel_do_flush()
so it is done before freeing of protocol pool.
