The netif_do_set_{ipaddr|netmask|gw} are static functions what won't be called
directly, thus move LWIP_ASSERT_CORE_LOCKED to netif_set_{ipaddr|netmask|gw}.
This avoid duplicated LWIP_ASSERT_CORE_LOCKED checking by netif_set_addr().

This ensures the core is locked when executing the init done function
passed to tcpip_init
The could manifest as a synchronization issue during early init if
another thread was in the LwIP context at the same time
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.
This fixes a bug in tcp_split_unsent_seg() where a chained pbuf was
not correctly updating pcb->snd_queuelen during trimming and snd_queuelen
would desynchronize if pbuf_realloc() freed some of the chain
Also, use pbuf_clen() for adding the new remaining segment rather than ++.
The new remaining segment should always be one pbuf due to the semantics
of PBUF_RAM, but this follows the best practice of using pbuf_clen()
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
Fix below build warning if LWIP_6LOWPAN_IPHC=0.

This fixes a bug in tcp_split_unsent_seg where oversized segments were not
handled during the split, leading to pcb->unsent_oversized and
useg->oversize_left getting out of sync with the split segment
This would result in over-writing the pbuf if another call to tcp_write()
happened after the split, but before the remainder of the split was sent in
tcp_output
Now pcb->unsent_oversized is explicitly cleared (because the remainder at
the tail is never oversized) and useg->oversized_left is cleared after it is
trimmed
This also updates the test_tcp_persist_split unit test to explicitly check for
this case
Current code only works if the argument happen to be named as fraghdr,
fix it.

The goto freepbuf code path is also used when IP_REASS_CHECK_OVERLAP=0.
Thus remove #if IP_REASS_CHECK_OVERLAP around the freepbuf label to fix

Use ip_addr_copy instead of ip_addr_set to avoid NULL test for
&sntp_last_server_address. This fixes build warning when
