explain_readdir_or_die - read directory entry and report errors

#include <libexplain/readdir.h>

struct dirent *explain_readdir_or_die(DIR *dir);

The explain_readdir_or_die function is used to call the readdir(2) system call. On failure an explanation will be printed to stderr, obtained from explain_readdir(3), and then the process terminates by calling exit(EXIT_FAILURE).

This function is intended to be used in a fashion similar to the following example:

explain_readdir_or_die(dir);
The dir, exactly as to be passed to the readdir(2) system call.
a pointer to a dirent structure, or NULL if end‐of‐file is reached. On failure, prints an explanation and exits.

read directory entry
explain readdir(2) errors
terminate the calling process
