From: Elijah Newren <newren@gmail.com>

This allows us to replace includes of cache.h with includes of the much
smaller alloc.h in many places.  It does mean that we also need to add
includes of alloc.h in a number of C files.

+ * Define your array with:

+ * - a pointer (`item`) that points at the array, initialized to `NULL`
+ *   (although please name the variable based on its contents, not on its
+ *   type);
+ *
+ * - an integer variable (`alloc`) that keeps track of how big the current
+ *   allocation is, initialized to `0`;
+ *
+ * - another integer variable (`nr`) to keep track of how many elements the
+ *   array currently has, initialized to `0`.
+ *
+ * Then before adding `n`th element to the item, call `ALLOC_GROW(item, n,
+ * alloc)`.  This ensures that the array can hold at least `n` elements by
+ * calling `realloc(3)` and adjusting `alloc` variable.

+ * ------------

+ * You are responsible for updating the `nr` variable.
+ *
+ * If you need to specify the number of elements to allocate explicitly
+ * then use the macro `REALLOC_ARRAY(item, alloc)` instead of `ALLOC_GROW`.

+ * Consider using ALLOC_GROW_BY instead of ALLOC_GROW as it has some

- * Dynamically growing an array using realloc() is error prone and boring.
- *
- * Define your array with:
- *
- * - a pointer (`item`) that points at the array, initialized to `NULL`
- *   (although please name the variable based on its contents, not on its
- *   type);
- *
- * - an integer variable (`alloc`) that keeps track of how big the current
- *   allocation is, initialized to `0`;
- *
- * - another integer variable (`nr`) to keep track of how many elements the
- *   array currently has, initialized to `0`.
- *
- * Then before adding `n`th element to the item, call `ALLOC_GROW(item, n,
- * alloc)`.  This ensures that the array can hold at least `n` elements by
- * calling `realloc(3)` and adjusting `alloc` variable.
- *
- * ------------
- * sometype *item;
- * size_t nr;
- * size_t alloc
- *
- * for (i = 0; i < nr; i++)
- * 	if (we like item[i] already)
- * 		return;
- *
- * // we did not like any existing one, so add one
- * ALLOC_GROW(item, nr + 1, alloc);
- * item[nr++] = value you like;
- * ------------
- *
- * You are responsible for updating the `nr` variable.
- *
- * If you need to specify the number of elements to allocate explicitly
- * then use the macro `REALLOC_ARRAY(item, alloc)` instead of `ALLOC_GROW`.
- *
- * Consider using ALLOC_GROW_BY instead of ALLOC_GROW as it has some
- * added niceties.
- *
- * DO NOT USE any expression with side-effect for 'x', 'nr', or 'alloc'.
