74800729c0 Proto: The active flag converted to actual fifth protocol state 
What was PS_DOWN before, is now PS_DOWN and PS_FLUSH.

7889f0c25b Neighbor locking: forgotten neighbors to unlink are actually a bug.

Tests for MRT are scarce and not automated for now, so it may behave
weirdly in corner cases.

b97d924e52 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.

330c71bd0a 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.

4ac55615e4 BGP and HCU uncorking is processed in the right loop 
closes #86

The uncork events are running from mainloop so these should just
dispatch the right event to the right loop. Doing anything long there
is bad for performance and latency as the uncork list may be huge.

3ed192edc3 Table: RCU synchronization moved to lfjour 
the sync is actually needed when the pages get freed, not precisely
after every item cleanup, as the data technically stays intact until the
deferred free's are called.

a146abc8fd Revert (partial) "Route attributes now use the common lockfree usecount" 
This partially reverts commit d617801c31.

The common lockfree doesn't work well for high-volume structures like
eattr cache because it expects the structure to be cleaned up by a
sweeper routine ... which is very ineffective for >1M records.

OTOH, we need the deferred ea_free in all cases ... so keeping that.
