  digests, copy-file: increase the IO buffer size from 4KiB to 32KiB
  
  This results in a significant decrease in syscall overhead
  giving a 3% speedup to the digest utilities for example
  (when processing large files from cache).
  Storage is moved from the stack to the heap as some
  threaded environments for example can have small stacks.
  
  * lib/copy-file.c (copy_file_preserving): Use a 32KiB malloced buffer
  * modules/copy-file: Depend on xalloc
