0dc0e9c2af More improvements to TreeView output for Window objects: 
(1) Show when the frame-spec is implied rather than explicit.
(2) Move the FILTER clause out from within the OVER clause, making it
a sibling of the OVER clause, to match syntax.

ed26483346 We learn that readdir_r() is deprecated in favor of plain old readdir(), which 
is now suppose to be threadsafe using thread-local storage.  So remove the
use of readdir_r() from the test code.  (SQLite itself never calls readdir()
or readdir_r()).
