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 Change-Id: Ia0251514e36a6242bbf3f03c5e0df123aba60ed2
