83045e9a1f Configuration obstacles made a separate, explicit structure 
With this, one can walk the obstacle list in a debugger and
easier see which specific object is holding the reference.

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.

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

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.

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.
