explain_unlink_or_die - delete a file and report errors

#include <libexplain/unlink.h>

void explain_unlink_or_die(const char *pathname);

The explain_unlink_or_die function is used to call the unlink(2) system call. On failure an explanation will be printed to stderr, obtained from explain_unlink(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_unlink_or_die(pathname);
The pathname, exactly as to be passed to the unlink(2) system call.
This function only returns on success. On failure, prints an explanation and exits.

delete a name and possibly the file it refers to
explain unlink(2) errors
exit(2)
terminate the calling process
