ANSI C conversion, libmudflap specialization, recursion limiting.
* splay-tree.h (splay_tree_{de,}allocate_fn): Remove allocation_data
argument and indirection function pointers, update callers.
(splay_tree_s): Add statistics and recursion control fields
num_keys, max_depth, depth, rebalance_p.
* splay-tree.c (splay_tree_splay_helper): Track recursion depth.
Back out of search if it exceeds limit.
(splay_tree_splay): Manage recursion limiting with rebalancing as
needed.
(splay_tree_new): More initialization.
(splay_tree_rebalance): New function.
(splay_tree_foreach): Rewrite using nonrecursive logic.
(splay_tree_xmalloc_allocate, splay_tree_xmalloc_deallocate):
Remove. Point indirect calls to mf-runtime.c's routines.
(splay_tree_compare_ints, splay_tree_compare_pointers): Remove unused
functions.
(splay_tree_delete, splay_tree_delete_helper): Ditto.
* testsuite/heap-scalestress.c: New test based on one from
