0ab21da820 Add multicast support to loopif
This commit adds support to send and receive multicast on the loopback
netif by enabling IGMP via NETIF_FLAG_IGMP

This commit also introduces an LwIP configuration option,
LWIP_LOOPIF_MCAST, to control the behavior and it defaults to off

177c06b1f1 - prework for fixing bug #45029: access IPv4 configuration of struct netif via new API (netif_ip4_addr()/netif_ip4_netmask()/netif_ip4_gw()) instead of accessing the struct member directly. This way, we can change the struct member types from ip4_addr_t to ip_addr_t;
- fixed some bugs in calls to ip4_addr*() where the cast to u8_t* did not reveal the wrong address type

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
test/*

no modifications were done on ip6_addr_t.
