It follows the general rule: If foobar.c needs a certain include file
but foobar.h doesn't already include it, then let foobar.c include it.
This rule enables modular development: If someone modifies safe-read.h
in the future, to remove <stddef.h> from there, he will update all the
callers of the functions safe_read() if needed, but he will usually
not add <stddef.h> to all .c files that #include "safe-read.h".
