951d0422fa Attributes: fix collision on free-lookup 
Freeing the eattrs is tricky as somebody else may find them
via RTA-unlocked lookup inbetween.

5c8179d63a Time accounting must be done by coarse timers 
on some ARM, the precise timers are too slow to be actually useful

4d01ca3e8f Every table has its own netindex now 
It's obnoxiously slow to walk over sparse tables.

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.

1032bf2543 Hash: Added a spinlocked variant 
The spinlocked hash has a main rw spinlock for the data blocks
and then a rw spinlock for each hash chain. Rehashing is asynchronous,
running from an event, and it happens chain-wise, never blocking more
than one chain at a time.

d4733b28d9 Dropping netindex fragile manipulation 
Now the netindex doesn't expose its internals and can be converted
to the spinlocked implementation much easier.

Maria Matejka
499d5e6fb3 ROA tables have now an auxiliary table 
There is an IP table for every ROA table, holding special records
combining all known ROAs for every top-prefix.

The ROA digestor is now an IP digestor, running over the auxiliary
table.

The sending channel may be already gone when rte_free_deferred()
is finally called so we have to log about route freeing in the
synchronous call instead.

dbe246a4bd Proto: fix reimporter crash on shutdown
