-string_pool API
-===============
-
-The string_pool API provides facilities for replacing strings
-with integer keys that can be more easily compared and stored.
-The facilities are designed so that one could teach Git without
-too much trouble to store the information needed for these keys to
-remain valid over multiple executions.
-
-Functions
----------
-
-pool_intern::
-	Include a string in the string pool and get its key.
-	If that string is already in the pool, retrieves its
-	existing key.
-
-pool_fetch::
-	Retrieve the string associated to a given key.
-
-pool_tok_r::
-	Extract the key of the next token from a string.
-	Interface mimics strtok_r.
-
-pool_print_seq::
-	Print a sequence of strings named by key to a file, using the
-	specified delimiter to separate them.
-
-	If NULL (key ~0) appears in the sequence, the sequence ends
-	early.
-
-pool_tok_seq::
-	Split a string into tokens, storing the keys of segments
-	into a caller-provided array.
-
-	Unless sz is 0, the array will always be ~0-terminated.
-	If there is not enough room for all the tokens, the
-	array holds as many tokens as fit in the entries before
-	the terminating ~0.  Return value is the index after the
-	last token, or sz if the tokens did not fit.
-
-pool_reset::
-	Deallocate storage for the string pool.

-Motivation
-==========
-
-Treaps provide a memory-efficient binary search tree structure.
-Insertion/deletion/search are about as about as fast in the average
-case as red-black trees and the chances of worst-case behavior are
-vanishingly small, thanks to (pseudo-)randomness.  The bad worst-case
-behavior is a small price to pay, given that treaps are much simpler
-to implement.
-
-API
-===
-
-The trp API generates a data structure and functions to handle a
-large growing set of objects stored in a pool.
-
-The caller:
-
-. Specifies parameters for the generated functions with the
-  trp_gen(static, foo_, ...) macro.
-
-. Allocates a `struct trp_root` variable and sets it to {~0}.
-
-. Adds new nodes to the set using `foo_insert`.  Any pointers
-  to existing nodes cannot be relied upon any more, so the caller
-  might retrieve them anew with `foo_pointer`.
-
-. Can find a specific item in the set using `foo_search`.
-
-. Can iterate over items in the set using `foo_first` and `foo_next`.
-
-. Can remove an item from the set using `foo_remove`.
-
-Example:
-
-----
-struct ex_node {
-	const char *s;
-	struct trp_node ex_link;
-};
-static struct trp_root ex_base = {~0};
-obj_pool_gen(ex, struct ex_node, 4096);
-trp_gen(static, ex_, struct ex_node, ex_link, ex, strcmp)
-struct ex_node *item;
-
-item = ex_pointer(ex_alloc(1));
-item->s = "hello";
-ex_insert(&ex_base, item);
-item = ex_pointer(ex_alloc(1));
-item->s = "goodbye";
-ex_insert(&ex_base, item);
-for (item = ex_first(&ex_base); item; item = ex_next(&ex_base, item))
-	printf("%s\n", item->s);

-Functions
----------
-
-trp_gen(attr, foo_, node_type, link_field, pool, cmp)::
-
-	Generate a type-specific treap implementation.
-+
-. The storage class for generated functions will be 'attr' (e.g., `static`).
-. Generated function names are prefixed with 'foo_' (e.g., `treap_`).
-. Treap nodes will be of type 'node_type' (e.g., `struct treap_node`).
-  This type must be a struct with at least one `struct trp_node` field
-  to point to its children.
-. The field used to access child nodes will be 'link_field'.
-. All treap nodes must lie in the 'pool' object pool.
-. Treap nodes must be totally ordered by the 'cmp' relation, with the
-  following prototype:
-+
-int (*cmp)(node_type \*a, node_type \*b)
-+
-and returning a value less than, equal to, or greater than zero
-according to the result of comparison.
-
-node_type {asterisk}foo_insert(struct trp_root *treap, node_type \*node)::
-
-	Insert node into treap.  If inserted multiple times,
-	a node will appear in the treap multiple times.
-+
-The return value is the address of the node within the treap,
-which might differ from `node` if `pool_alloc` had to call
-`realloc` to expand the pool.
-
-void foo_remove(struct trp_root *treap, node_type \*node)::
-
-	Remove node from treap.  Caller must ensure node is
-	present in treap before using this function.
-
-node_type *foo_search(struct trp_root \*treap, node_type \*key)::
-
-	Search for a node that matches key.  If no match is found,
-	result is NULL.
-
-node_type *foo_nsearch(struct trp_root \*treap, node_type \*key)::
-
-	Like `foo_search`, but if the key is missing return what
-	would be key's successor, were key in treap (NULL if no
-	successor).
-
-node_type *foo_first(struct trp_root \*treap)::
-
-	Find the first item from the treap, in sorted order.
-
-node_type *foo_next(struct trp_root \*treap, node_type \*node)::
-
-	Find the next item.
