This reverts commit 3a64d6491a1e83adcaf5f97edd18b7898dce241d. strlcpy already had a check to make sure that as long as the size passed in wasn't zero, it would leave enough space to write the final null. So, the only check that was necessary was to see if strlcpy was called with size = 0. strlcpy returns the number of bytes that it took, or would take, to write the entire string. There is no reason why bytes would usually end up equalling size, so this commit caused strlcpy to stop null terminating many strings.
