Also update log message for error-triggered startup delay.

Permit specifying neighbor address, AS number and port independently.
Add 'interface' parameter for specifying interface for link-local
sessions independently.

Thanks to Alexander V. Chernikov for the original patch.

This value is specified in documentation.

Make proto_config_new() use this info instead of supplied size.

When multiple protocols have a lock for the same IP address, it crashes
under some circumstances.

Thanks to Matthias Schiffer for the bugreport.

Thanks to Andrew (seti.kr.ua) for the bug report.

Configurable fast shutdown of a BGP session when an interface loses link.

Message 'Network not in table' was not reported if a network node without
any routes was found in a routing table.

Now the order is:

Up   -> iface, addr, neigh
Down -> neigh, addr, iface

It fixes the case when an iface appears, related static routes are
activated and exported to OSPF before the iface notification and
therefore forwarding addresses are not encoded in generated external
LSAs.

Shows routes that would be exported to the protocol but are rejected by
the export filter.

Thanks to João Taveira Araújo for the original patch.

When an interface goes down, (Linux) kernel removes routes pointing to
that ifacem but does not send withdraws for them. We rescan the
kernel table to ensure synchronization.

Thanks to Alexander Demenshin for the bugreport.
