Details:
The MDNS code makes use of snprintf() without including stdio.h:
src/apps/mdns/mdns.c:508: error: implicit declaration of function 'snprintf'
However, rather than adding the #include, I would prefer if MDNS did not use
snprintf() at all, or at least not directly. Many embedded applications avoid
using the C library's printf() altogether due to code size and stack usage
restrictions, and lwIP should not drag it in.
