Turning attention to some plumbing.
* unwind.c (uw_env_stack): New static variable.
(uw_unwind_to_exit_point): Maintain correct uw_env_stack
during unwinding.
(uw_find_env): Just retrieve the env stack pointer; no search.
(uw_push_env): Store a pointer to the previous
environmental frame and just initialize the bindings to nil.
No need to cons up a copy of the bindings from the previous frame.
(uw_get_func): Perform a search through the environment stack.
* unwind.h (struct uw_dynamic_env): New member, up_env.
