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.

1db43fc51d Separate out PPP processing 
So we can later call it on frames obtained from kernel ppp interface.

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.

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.

2229ac6a8a RA: Fix announcing on the right tunnel

e6a933153d RA: announce after the actions which may be dropping the session

05772e2295 Add periodic RA sends 
The RFC indeed say that we should send them periodically.  We were
previously only sending them along LCP echo replies, but echo requests
are typically sent only when there is no trafic, which RA need to be
sent even when there is trafic.

3667bdfe80 Also clamp MSS on IPv6 
Some routers erratically drop "Packet too big" icmp messages, and PMTU
discovery then doesn't work. We can however easily clamp MSS on IPv6 too.

1a89fc3f63 initippool: drop redundant memset 
The size of the memset was just wrong, but the data has already been
zeroed in initdata so we can just remove it.

7bf791816c Fix the password used when acting as LAC 
When acting as LNS, we have to answer challenges with our own secret, but
when acting as LAC, we have to answer challenges with the LNS secret, not
ours.

8e7bfa9a77 Add mp_mrru option 
Some equipments seem not able to actually put options in Configure-Reject
messages, so we then have to disable MRRU by hand.

af92de5eeb processudp: fix memory leak 
send/recvchalresponse should be freed before early returns in the function,
as there are code paths where they would be allocated before these.

Note free is no-op on null pointer so checking for non-null value is useless.
