Derrick Stolee 080ab56a46 cache-tree: implement cache_tree_find_path() ...

Given a 'struct cache_tree', it may be beneficial to navigate directly
to a node within that corresponds to a given path name. Create
cache_tree_find_path() for this function. It returns NULL when no such
path exists.

The implementation is adapted from do_invalidate_path() which does a
similar search but also modifies the nodes it finds along the way. The
method could be implemented simply using tail-recursion, but this while
loop does the same thing.

This new method is not currently used, but will be in an upcoming
change.
