* gc.c: rename heap management functions with prefix "heap_".
* allocate_sorted_array() -> heap_allocate_sorted_array().
* slot_add_freeobj() -> heap_slot_add_freeobj().
* assign_heap_slot() -> heap_assign_slot().
* add_heap_slots() -> heap_add_slots().
* init_heap() -> heap_init().
* set_heap_increment() -> heap_set_increment().
* gc.c (initial_expand_heap): inlined in rb_gc_set_params().
