/**
* avl - Key-value dictionary based on AVL trees
*
* A simple, well-tested implementation of AVL trees for mapping
* unique keys to values. This implementation supports insertion,
* removal, lookup, and traversal.
*
* An AVL tree is a self-balancing binary tree that performs
* insertion, removal, and lookup in O(log n) time per operation.
*
* Example:
* #include <ccan/avl/avl.h>
*
* #include <stdio.h>
* #include <stdlib.h>
* #include <string.h>
*
* struct tally {
* long count;
* };
* #define new_tally() calloc(1, sizeof(struct tally))
*
* static void chomp(char *str)
* {
* char *end = strchr(str, 0);
* if (end > str && end[-1] == '\n')
* end[-1] = 0;
* }
*
* int main(void)
* {
* AVL *avl = avl_new((AvlCompare) strcmp);
* AvlIter i;
* struct tally *tally;
* char line[256];
*
* while (fgets(line, sizeof(line), stdin))
* {
* chomp(line);
*
* tally = avl_lookup(avl, line);
* if (tally == NULL)
* avl_insert(avl, strdup(line), tally = new_tally());
*
* tally->count++;
* }
*
* avl_foreach(i, avl) {
* char *line = i.key;
* struct tally *tally = i.value;
*
* printf("% 5ld: %s\n", tally->count, line);
*
* free(line);
* free(tally);
* }
*
* avl_free(avl);
*
* return 0;
* }
