1. remove most occurences of strcpy/strcat …

   those functions are insecure and in the case of strcat even slow,
   since the strlen has to be checked on each call.
   they are considered a code-smell; instead, snprintf should be used.
   
   snprintf(buf, sizeof buf, "%s", mystring) is the only way offered
   by C99 to do a bounds-checked copy of a string (and after parsing
   the format string (which should only take a handful of cycles),
   performance is identical to a naive strcpy implementation using
   a for loop until 0 is hit).
   
   note that strncpy() always fills the entire buffer, so it is a
   performance hog.
