d87740bb96 mdns: Fix multicast destination check for IPv6 
This broke when IPv6 got scopes added. Scopes/zones are checked
even if none of the compared addresses are link local.

Result of the bug was that IPv6 replies were always sent unicast to
the source instead of to the multicast address.

Add ip-generic version that ignores IP zone info, since the v6 group
address is not tied to any netif.

b536fd9767 Apply modified version of bug #52747: mdns resp: separate the announce function and add netifapi support for it 
Changes made by me:
- Move all error handling code into mdns_resp_announce() so it can be safely used by external code
- Remove mdns_resp_netif_settings_changed() because it is the same as mdns_resp_announce() after my changes
- Declare #define for a "thread-safe" version of mdns_resp_announce in mdns.h instead of netifapi.h - I don't want to intermix netif API with APPs

Our Air Quality
1b57284bb4 mdns: guard against there being no ip4 address. 
* Avoid announcing to an interface with no ip4addr.

* Avoid emitting A answers if there is no ip4 address.

Our Air Quality
5eff45cac0 Correct a few uses of sizeof(ip6_addr_t) to sizeof(ip6_addr_p_t) 
The ip6_addr_t structure may have an addition slot so is not necessarily
the size of an ipv6 address, so some uses of sizeof(ip6_addr_t) were not
correct.

557a11047d Patch #9307: Replace mem_malloc+memset with mem_calloc 
Aside from reducing source code, on systems which use MEM_LIBC_MALLOC,
this has the potential to improve performance depending on the underlying
memory allocator

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.
