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.

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.

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!

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.

C Compiler Attribute Cleanup Test
...
There is a long-known CC attribute cleanup which allows to call a custom
cleanup function when an auto-storage variable ceases to exist. We're
gonna use it for end-of-loop and leave-locked-block macros.
This commit adds a static unit test for this compiler feature to be sure
that it really does what we want. We're looking forward to the next ISO
C norm where this may finally get a nice syntax and standardization.
