That is kind of the problem with the whole change,
however we do not really have untrusted input here,
and the normal avstrlcpy etc. would just silently
truncate.
What we'd really want is a strcpy that fails
to compile when the string does not fit.
Unfortunately I know of none such, and even
just compiletime asserts are a problem by
themselves.
