William Wilgus f6c719d7ec replace strlcpy with strmemccpy
replace applicable calls to strlcpy with calls to strmemccpy
which null terminates on truncation

in theory the strmemccpy calls should be slightly faster since they
don't traverse the rest of the source string on truncation
but I seriously doubt there is too much of that going on in the code base
