> what is the reason for removing `xstrdup.patch` instead of updating it?

What do you want to update?

The function does no longer exist and the file is also removed.

In `lib/alloc.c` a comment says:
```
/* Replacements for malloc and strdup with error checking.  Too trivial
   to be worth copyrighting :-).  I did that because a lot of code used
   malloc and strdup without checking for NULL pointer, and I like some
   message better than a core dump...  --marekm

   Yeh, but.  Remember that bailing out might leave the system in some
   bizarre state.  You really want to put in error checking, then add
   some back-out failure recovery code. -- jfh */
```

As I understand the patch is no longer needed.
