Ben Wiederhake 9795c61464 LibC: Prevent slowness and overrun in strdup/strndup ...

strdup: Because the length is already known at the time of copying, there is
no need to use strcpy (which has to check every single byte, and thus tends
to be slower than memcpy).

strndup: If 'str' is not NUL-terminated, strndup used to run off into the
adjacent memory region. This can be fixed by using the proper strlen variant:
strnlen.
