9ba9dee2aa tcp: advance next seq nr for zero window probes 
It is possible that the byte sent as a zero window probe is accepted
and acknowledged by the receiver side without the window being opened.
In that case, the stream has effectively advanced by one byte, and
since lwIP did not take this into account on the sender side, the
result was a desynchronization between the sender and the receiver.
That situation could occur even on a lwIP loopback device, after
filling up the receiver side's receive buffer, and resulted in an ACK
storm. This patch corrects the problem by advancing the sender's next
sequence number by one as needed when sending a zero window probe.

ee27daffc4 Fix bug #48876: nd6: timers should be in ticks, not ms 
delay_time and stale_time are ticks now.
reachable_time and invalidation_timer are untouched since they may originate from telegram values -> not converting them to ticks avoids an integer division

5e15125b3d igmp: Fix optimized code by always skipping the first entry in the linked groups list 
commit 8c52afb6ca ("igmp: Optimize code by always skipping the first entry in the linked groups list - it is always the "allsystems" entry")
accidently changes the code logic. it should check groupref rather than group.

c7c6b7ce93 Rework IGMP and MLD6 code to store group info per-netif. 
Reasoning:
- Makes code in single-netif case perform better and smaller
- IGMP / MLD6 code is a little bit easier to read and understand
- Easier to get multicast groups per netif when implementing drivers

Downside: In multi-netif mode, there are two more pointers on each netif, even if IGMP/MLD6 is not used on it. But these systems should not be so memory-constrained that this will matter.

c9bae5ea9b Fix bug #49134: Do not announce invalid IPv4 address via mDNS 
In a dual stack configuration it is not really feasible to wait
until the IPv4 address is valid before starting the mDNS responder.
If there is no DHCPv4 server in the network, the IPv4 address may
never become valid, which should however not preclude IPv6 mDNS
from working.
