10bb1c1e9d Real almost-lockless feeds and more pull-like exports 
Introducing a new omnipotent internal API to just pass route updates
from whatever point wherever we want.

From now on, all the exports should be processed by RT_WALK_EXPORTS
macro, and you can also issue a separate feed-only request to just get a
feed and finish.

The exporters can now also stop and the readers must expect that to
happen and recover. Main tables don't stop, though.

091130e84b Using ea_lookup_tmp() for temporarily keeping attribute references 
To avoid needs for keeping local temporary references for attributes,
now one can use ea_lookup_tmp() to ensure that the attributes are
valid and stored until the task ends. After that, the attributes are
automatically unref'd and also deallocated if needed.

2b38a833cd Avoiding RCU synchronization deadlock when locking in critical section 
Explicitly marking domains eligible for RCU synchronization. It's then
forbidden to lock these domains in RCU critical section to avoid
possible deadlock.

6a13c02d3b Removed the obsolete birdloop flagger 
This was useful when events were locking. As now sending events is lockless,
we can drop this obsolete routine for good.

114be2af28 Filter: Add route attribute gw_mpls_stack 
Add route attribute gw_mpls_stack to make MPLS stack of route nexthop
accessible from filters. Its type is T_CLIST, which is really not correct
(as it is a list, while T_CLIST is a set). Therefore, we keep this
attribute *undocumented* and it will be *changed* without further notice.

Based on a patch from Trisha Biswas <tbiswas@fastly.com>, thanks!

574d7eb241 BGP: Allow multiple EBGP neighbors with the same peer. 
We can distinguish BGP sessions if at least one side uses a different IP
address. Extend olock mechanism to handle local IP as a part of key, with
optional wildcard, so BGP sessions could local IP in the olock and not
block themselves.

The UDP logging had to be substantially rewritten due to a different
logging backend and reconfiguration mechanisms.

54d5e36ec0 Index of different net_addr values for hashing and bit-marking

known net_addr values. This is a data structure keeping this mapping.
