* src/number.c (numset_add_num): add debugging output to print the args.

(numset_release): likewise
(numset_request): add debugging output to print the requested number

* src/manage.c (withdraw_window): Print an error when withdrawing
a window who's number is -1.

* src/main.c (clean_up): free the global frame numset.
(free_screen): don't free the screen's numset, since it's a
pointer to the global numset.

* src/group.c (group_del_window): don't release the window number
here. It's already been done in group_unmap_window.

* src/events.c (configure_request): only change the stack mode for
non withdrawn windows.
