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.

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.

Recent changes in neighbor code caused RIP to access neighbor field which
is NULL during interface/neighbor removal and caused crash when debug
messages are enabled. Use correct field to get iface from neighbor.

0f88200247 BGP: Fix processing of IPv6 Flowspec 
During NLRI parsing of IPv6 Flowspec, dst prefix was not properly
extracted from NLRI, therefore a received flow was stored in a different
position in flowspec routing table, and was not reachable by command
'show route <flow>'.

Add proper prefix part accessors to flowspec code and use them from BGP
NLRI parsing code.

Thanks to Alex D. for the bugreport.

active, channel reload is done from it instead of doing full route
refresh. So in this case we request it internally.

typecasts.

exported (post-filtered) routes are stored there. An export table can be
examined using e.g. 'show route export table bgp1.ipv4'.
