add context pointer to read_tree_recursive()

Browse Source 
Add a pointer parameter to read_tree_recursive(), which is passed to the
callback function.  This allows callers of read_tree_recursive() to
share data with the callback without resorting to global variables.  All
current callers pass NULL.
