Under specific circumstances there might be two mixed-up netlink sessions (one for scan, the other for route change request). This patch separates netlink scans and requests to two fds (and seq counters). This should fix http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=428865

Old AS path maching supposes thath AS number appears only once in AS path, but that is not true. It also contains some bugs related to AS path sets. New code does not use any assumptions about semantic structure of AS path. It is asymptotically slower than the old code, but on real paths it is not significant. It also allows '?' for matching one arbitrary AS number.

Cryptographic authentication in OSPF is defective by design - there might be several packets independently sent to the network (for example HELLO, LSUPD and LSACK) where they might be reordered and that causes crypt. sequence number error. That can be workarounded by not incresing sequence number too often. Now we update it only when last packet was sent before at least one second. This can constitute a risk of replay attacks, but RFC supposes something similar (like time in seconds used as CSN).

If a DBDES packet from a master to a slave is lost, then the old code does not retransmit it and instead send a next one with the same sequence number. That leads to silent desynchronization of LSA databases.

Prefix sets were broken beyond any repair and have to be reimplemented. They are reimplemented using a trie with bitmasks in nodes. There is also change in the interpretation of minus prefix pattern, but the old interpretation was already inconsistent with the documentation and broken. There is also some bugfixes in filter code related to set variables.

Routes comming through pipe from primary to secondary table were filtered by both EXPORT and IMPORT filters, but they should be only filtered by EXPORT filters.

KRF_INSTALLED flag was not cleared during reconfiguration that lead to not removing routes during reconfigure when export rules changed. We also should not try to remove routes we didi not installed, on Linux this leads to warnings (as kernel checks route source field and do not allow to remove non-bird routes) but we should not rely on it.

AS4 optional attribute errors were handled by session drop (according to BGP RFC). This patch implements error handling according to new BGP AS4 draft (*) - ignoring invalid AS4 optional attributes. (*) http://www.ietf.org/internet-drafts/draft-chen-rfc4893bis-02.txt

This patch extends the length for attributes from 1024 to 2048 (because both AS_PATH and AS4_PATH attributes take 2+4 B per AS). If there is not enough space for attributes, Bird skips that route group. Old behavior (skipping remaining attributes) leads to skipping required attributes and session drop.

When slave was in full state, it didn't retransmit lost packets. That leads to OSPF connection locked in states loading-full.

When OSPF neighbor state drops down to EXSTART, clear LSA request and retransmit lists, as specified by RFC. I hope that this will prevent oscillations between EXSTART and LOADING states, which sometimes happened. It also contains related fix from Yury Shevchuk that properly resets DB summary list iterator.
