-/**
- * hashtable - hash table routines
- *
- * A hash table is an efficient structure for looking up keys.  This version
- * grows with usage and allows efficient deletion.
- *
- * Caveat: pointers placed into the hash must be aligned to 64 bits.
- * ie. from malloc or because the structure they point to is aligned.
- * An assert will be raised if this isn't true.
- *
- * Example:
- *	#include <ccan/hashtable/hashtable.h>
- *	#include <ccan/hash/hash.h>
- *	#include <stdio.h>
- *	#include <err.h>
- *	#include <string.h>
- *	
- *	struct name_to_digit {
- *		const char *name;
- *		unsigned int val;
- *	};
- *	
- *	static struct name_to_digit map[] = { 
- *		{ "zero", 0},
- *		{ "one", 1 },
- *		{ "two", 2 },
- *		{ "three", 3 },
- *		{ "four", 4 },
- *		{ "five", 5 },
- *		{ "six", 6 },
- *		{ "seven", 7 },
- *		{ "eight", 8 },
- *		{ "nine", 9 }
- *	};
- *	
- *	// Wrapper for rehash function pointer.
- *	static unsigned long rehash(const void *e, void *unused)
- *	{
- *		return hash_string(((struct name_to_digit *)e)->name);
- *	}
- *	
- *	// Comparison function.
- *	static bool streq(const void *e, void *string)
- *	{
- *		return strcmp(((struct name_to_digit *)e)->name, string) == 0;
- *	}
- *	
- *	// We let them add their own aliases, eg. --alias=v=5
- *	static void add_alias(struct hashtable *ht, const char *alias)
- *	{
- *		char *eq;
- *		struct name_to_digit *n;
- *	
- *		n = malloc(sizeof(*n));
- *		n->name = strdup(alias);
- *	
- *		eq = strchr(n->name, '=');
- *		if (!eq || ((n->val = atoi(eq+1)) == 0 && !strcmp(eq+1, "0")))
- *			errx(1, "Usage: --alias=<name>=<value>");
- *		*eq = '\0';
- *		hashtable_add(ht, hash_string(n->name), n);
- *	}

- *			errx(1, "Usage: %s [--alias=<name>=<val>]... <str>...",
- *			     argv[0]);
- *	
- *		// Create and populate hash table.
- *		ht = hashtable_new(rehash, NULL);
- *		for (i = 0; i < sizeof(map)/sizeof(map[0]); i++)
- *			hashtable_add(ht, hash_string(map[i].name), &map[i]);
- *	
- *		// Add any aliases to the hash table.
- *		for (i = 1; i < argc; i++) {
- *			if (!strncmp(argv[i], "--alias=", strlen("--alias=")))
- *				add_alias(ht, argv[i] + strlen("--alias="));
- *			else
- *				break;
- *		}
- *	
- *		// Find the other args in the hash table.
- *		for (val = 0; i < argc; i++) {
