0034abfa45 Always check whether netif_default is NULL 
In general, netif_default may be NULL, and various places in the code
already check for this case before attempting to dereference the
netif_default pointer.  Some places do not perform this check though,
and may cause null pointer dereferences if netif_default is not set.
This patch adds NULL checks to those places as well.

13fb616bb2 Cleanup hton*/ntoh* function handling and platform abstraction 
Let lwip use functions/macros prefixed by lwip_ internally to avoid naming clashes with external #includes.
Remove over-complicated #define handling in def.h
Make functions easier to override in cc.h. The following is sufficient now (no more LWIP_PLATFORM_BYTESWAP):
#define lwip_htons(x) <your_htons>
#define lwip_htonl(x) <your_htonl>

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.

4d4710dadf Bug #49125 addendum: Remove group from list before callback 
When leaving a multicast group, remove the group from the list
before invoking the MAC filter callback. This avoids the need
for the callee to skip over the group that is about to be deleted.
