a957ff08ee Throttle switching kernel acceleration 
Creating/destroying interfaces etc. does take some time. When e.g. receiving
a lot of sessions as new slave, we don't want to stay stuck creating
hundreds of interfaces while we are already receiving control messages
that we have to forward to master not too late. Switching kernel
acceleration can wait a bit most of the time.

c8c197bf3a processppp: fix IP log when tunnel IP source change 
fmtaddr formats the string to a static buffer that must be selected
manually, but this log message was re-using the same buffer.

Use another index for 2nd IP so we get to know which is what.

e53fccd36c Add route for session-specific subprefix of the ipv6 prefix 
Otherwise with kernel acceleration we would only have the same /64 route
on all ppp devices. We need separate /96 routes on each ppp device for
packets of the /96 subprefix to be routed to the correct session.

b2bc6da827 Add support for deleting all kernel tunnels/sessions 
Unfortunately, tunnels and session can survive us, so we have to drop any
tunnel/session left from a previous instance that might have crashed.

e442a69fc1 cluster: try make the cluster socket high-priority 
The heartbeat messages, notably, should really not be lost, otherwise the
cluster will dismantle itself if some very-high trafic is filling packet
queues.

9daccab8ba shutdown_handler: really shutdown when we are last 
If we are a master and we don't have peers, there is no use keeping the
sessions alive, when we'll restart we will have forgotten them all.
Better gracefully close them, so they can be quickly respawn on restart,
instead of having to wait for timeouts.
