        many of seemingly-safe strcpy are safe because:
        - foo.h defines destination buffer bigger than/same size as source
          (intentionally or by coincidence?  they are hardcoded numbers, not
          macros, in many cases!)
        - MALLOC(len + 1) is performed right before strcpy

        by using strlcpy, we can avoid any overrun mistakes even when foo.h
        changes, MALLOC() changed by someone, or whatever assumption changes.

        i am doing it with reason.  care to provide asm version of strlcpy? :-)
