stringop-truncation warnings
G++ 8 has a new warning stringop truncation which is emitted when strncat or strncpy (only the second in kea) fails to terminate (i.e. append a null character) its result.
There are on Fedora 28 spurious warnings on local/unix socket address or ifname because they are filled using strncpy.
I have a mixed feeling about this: IMHO the issue is not in Kea but in the system header files which should add a nonstring
attribute but did not, so no action is a possible answer to this...
