/**
* objset - unordered set of pointers.
*
* This code implements a very simple unordered set of pointers. It's very
* fast to add and check if something is in the set; it's implemented by
* a hash table.
*
* License: LGPL (v2.1 or any later version)
*
* Example:
* // Silly example to determine if an arg starts with a -
* #include <ccan/objset/objset.h>
* #include <stdio.h>
*
* struct objset_arg {
* OBJSET_MEMBERS(const char *);
* };
*
* int main(int argc, char *argv[])
* {
* struct objset_arg args;
* unsigned int i;
*
* objset_init(&args);
* // Put all args starting with - in the set.
* for (i = 1; i < argc; i++)
* if (argv[i][0] == '-')
* objset_add(&args, argv[i]);
*
* if (objset_empty(&args))
* printf("No arguments start with -.\n");
* else {
* for (i = 1; i < argc; i++)
* if (objset_get(&args, argv[i]))
* printf("%i,", i);
* printf("\n");
* }
* return 0;
* }
* // Given 'a b c' outputs No arguments start with -.
* // Given 'a -b c' outputs 2,
* // Given 'a -b -c d' outputs 2,3,
