93c3923462 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.

09d99617d3 Table feeds are now lockless
This commit makes the route chains in the tables atomic. This allows not
only standard exports but also feeds and bulk exports to be processed
without ever locking the table.

Design note: the overall data structures are quite brittle. We're using
RCU read-locks to keep track about readers, and we're indicating ongoing
work on the data structures by prepending a REF_OBSOLETE sentinel node
to make every reader go waiting.

All the operations are intended to stay inside nest/rt-table.c and it
may be even best to further refactor the code to hide the routing table
internal structure inside there. Nobody shall definitely write any
routines manipulating live routes in tables from outside.

cf4c91a07e Fixed best route announcements after NHU
When more routes in one net changed at once, the best route
announcements were inconsistent which confused exporters.

068b1520d4 Lockless hostentry resolution
Now the hostentry doesn't need to lock table, instead it tracks the
hostentry version and retries if the hostentry changed while updating.

27f2fd4aa9 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.

a0b4835253 MPLS: Fix issue with recursive MPLS routes
