71810d0415 ipv6: adjust MLD membership on address state changes 
If MLD support is enabled, each locally assigned IPv6 address in the
appropriate state must be a member of the solicited-node multicast
group corresponding to that address.  Ensure that this is always the
case by (re-)deciding on the membership upon every address state
change.  By doing so, this patch enforces that user-initiated state
changes to addresses (e.g., deletion) never cause a desynchronization
with the corresponding solicited-node multicast group membership,
thereby making such user-initiated state changes simpler and safer.

1d4cbe768d netif: Add proper lock protect for accessing netif->loop_first 
All the reset part of the code accessing netif->loop_first has lock protection,
the only missing part is "while (netif->loop_first != NULL)".
Fix it by adding lock protect around the while loop.

Also convert the code to use while{} loop instead of do .. while{} loop,
then we can avoid NULL test for in pointer in each loop and reduce a level of indent.

1c9e603299 netif: fix reset of IPv6 addresses in netif_add() 
Previously, only the state of the first IPv6 address would be reset,
thus possibly keeping other addresses valid (even though zeroed).

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>

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.
