static

Helper for streamer_tree_cache_insert and streamer_tree_cache_insert_at.
   CACHE, T, and IX_P are as in streamer_tree_cache_insert.

   If INSERT_AT_NEXT_SLOT_P is true, T is inserted at the next available
   slot in the cache.  Otherwise, T is inserted at the position indicated
   in *IX_P.

   If T already existed in CACHE, return true.  Otherwise,
   return false.

bool streamer_tree_cache_lookup	(	struct streamer_tree_cache_d *	cache,

Return true if tree node T exists in CACHE, otherwise false.  If IX_P is
   not NULL, write to *IX_P the index into the cache where T is stored
   ((unsigned)-1 if T is not found).
