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.

877fcb35f4 fix return type of netif_add_ip6_address mismatch 
the netif_add_ip6_address function was declared err_t in
src/include/lwip/netif.h, but defined as s8_t (the default value of
err_t) in its implementation in src/core/netif.c.

this causes "conflicting types for 'netif_add_ip6_address'" errors if
err_t is defined differently in cc.h (as for example recommended in
[1]).

as it only returns error constants, it is changed to use err_t
throughout.

5b0d9338fd netif, loopif: set link up on loopback interface 
When LWIP_HAVE_LOOPIF is enabled, a separate loopback interface is added
as a netif. A netif need to have its link state set to up to be able to be
selected as a route in ip4_route or ip6_route.

The regression appears to be when bug #43904 (ip_route() and ip6_route()
must detect linkup status) was fixed.

Furthermore, there is no point of having the loopif down by default.

9f065c0ea5 (api break) qualify ip_addr_t as const where feasible 
this changes the callback signatures of the ip_output and the
{udp,raw}_recv functions.

changes were made by going through all header files, searching for
occurrences of ip_addr_t, qualifying them as const and if required
modifying the corresponding c files, looking for other uses of ip_addr_t
that would be required.

the following header files were not treated as i'm not using them and
wouldn't see them compiled: api.h api_msg.h dhcp.h dns.h igmp.h
netifapi.h pppapi.h snmp.h snmp_msg.h snmp_structs.h ppp.h pppol2tp.h
