explain_realloc_or_die - Allocate and free dynamic memory and report errors

#include <libexplain/realloc.h>

void explain_realloc_or_die(void *ptr, size_t size);

The explain_realloc_or_die function is used to call the realloc(3) system call. On failure an explanation will be printed to stderr, obtained from explain_realloc(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:

void *new_ptr = explain_realloc_or_die(ptr, size);
The ptr, exactly as to be passed to the realloc(3) system call.
The size, exactly as to be passed to the realloc(3) system call.
This function only returns on success. On failure, prints an explanation and exits.
