8d4cd47d40 Proto: adding lockless state table and journal 
To allow reading of protocol states from other protocols or completely
different routines, we have to export these states to data structures
not requiring to lock the protocol loops.

On one hand, this doesn't give the reader the actual state "right now",
on the other hand, getting that is impossible in a properly
multithreaded environment and you will always get the information with
some (little but noteworthy) delay.

This implementation handles only the basic state information of the
protocols, common for all the protocols. Adding protocol-specific state
information should be done by implementing the protocol hook init_state().

Channel information is stored but not announced, as we don't need the
announcements for now.

64c6252e7c More attribute types: pointers, strings, btime 
For the upcoming rework of protocol state information propagation,
we need some more eattr types to be defined.

These types are probably not defined completely and before using
them for route attributes, you should check that they don't lack
some crucial methods.

716472957b Kernel: protocol shuts down synchronously 
Before this commit, on kernel shutdown, the routes were re-exported by
the regular export but treated as withdraw. This was too hairy and
caused unnecessary complexity of the protocol's state machine.

Instead of that, we found out that it makes more sense to just refeed
the routes synchronously and convert to withdraw. This is done by the
direct export access instead of the channel.

It would (maybe) make more sense to run export filters on this in case
the export filter updates the krt_metric attribute, but as this doesn't
work on regular withdraw anyway, it's better for now to just let it be
and maybe somebody in the future fixes this issue.

a4a7e09478 Revert "BGP: Export uses common attribute cache" 
This reverts commit d01a7c2bda.

It seems that the performance penalty in global ea cache is actually
very high so returning back to local attribute caches in every BGP.
