llmnrd: Use MAXHOSTNAMELEN for hostname buffer and zero-terminate string
Use MAXHOSTNAMELEN defined in sys/param.h to determine the size of the hostname buffer to allocate. Also make sure the string is properly zero-terminated in all cases, as in some cases it might be undefined whether a truncated string is properly terminated. Note: Also remove a TODO comment, as watching for hostname changes at runtime is outside the scope of llmnrd (also, avahi behaves the same). Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
