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

50a5d85f45 tcp: handle segmentation oversize during segment split (bug #52676)
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

920ee2d07e sntp: use const for servername
This adds const to the sntp servername get/set API and internal storage

SNTP's usage of this name is read only and SNTP only passes it to dns_gethostbyname()

This was found by compiling with GCC -Wwrite-strings which makes the literal
SNTP_SERVER_ADDRESS a const string. This then produced warnings with sntp_init()'s
call to sntp_setservername()
