836e857b30 Sockets: Unified API for main and other loops
Now sk_open() requires an explicit IO loop to open the socket in. Also
specific functions for socket RX pause / resume are added to allow for
BGP corking.

And last but not least, socket reloop is now synchronous to resolve
weird cases of the target loop stopping before actually picking up the
relooped socket. Now the caller must ensure that both loops are locked
while relooping, and this way all sockets always have their respective
loop.

571c4f69bf More efficient IO loop event execution to avoid long loops
If there are lots of loops in a single thread and only some of the loops
are actually active, the other loops are now kept aside and not checked
until they actually get some timers, events or active sockets.

This should help with extreme loads like 100k tables and protocols.

Also ping and loop pickup mechanism was allowing subtle race
conditions. Now properly handling collisions between loop ping and pickup.

731ec00840 Allowing to restart a route refresh.
Repeated pipe refeed should not end route refresh as the prune routine
may start pruning otherwise valid routes.

The same applies for BGP repeated route refresh.

97d2875e99 Fixed bad filter re-evaluation with import table if filtered->accepted
The import table feed wasn't resetting the table-specific route values
like REF_FILTERED and thus made the route look like filtered even though
it should have been re-evaluated as accepted.

2898f8f177 BGP: LLGR Staleness optimization dropped.
This brought unnecessary complexity into the decision procedures while the
performance aspects weren't worth it. It just saved one ea_list traversal
when many others are also done.

6899ba2232 Conf: Fix too early free of old configuration
The change 371eb49043 introduced early free
of old_config. Unfortunately, it did not properly check whether it is not
still in use (blocked by obstacle during reconfiguration). Fix that.

It also means that we still could have a short peak when three configs
are in use (when a new reconfig is requeste while the previous one is
still active).

c354e8f4c1 Interface updates are asynchronous
Instead of propagating interface updates as they are loaded from kernel,
they are enqueued and all the notifications are called from a
protocol-specific event. This change allows to break the locking loop
between protocols and interfaces.

Anyway, this change is based on v2 branch to keep the changes between v2
and v3 smaller.

e077d0e770 Moved interface list flush to device protocol cleanup hook.
The interface list must be flushed when device protocol is stopped. This
was done in a hardcoded specific hook inside generic protocol routines.
The cleanup hook was originally used for table reference counting late
cleanup, yet it can be also simply used for prettier interface list flush.

05d8c3699d Object locks use events
Instead of calling custom hooks from object locks, we use standard event
sending mechanism to inform protocols about object lock changes. This is
a backport from version 3 where these events are passed across threads.

This implementation of object locks doesn't use mutexes to lock the
whole data structure. In version 3, this data structure may get accessed
from multiple threads and must be protected by mutex.

f7c2a886c9 Object locks use events
Instead of calling custom hooks from object locks, we use standard event
sending mechanism to inform protocols about object lock changes. As
event sending is lockless, the unlocking protocol simply enqueues the
appropriate event to the given loop when the locking is done.

This reverts commit 7144c9ca46.

The onlink attribute implementation collides with the nexthop attribute
behavior in v3; keeping it aside until finding out how to reimplement it
correctly.
