3de52e8fa0 Including the phrase EXCLUDE NO OTHERS in the frame-spec of a window function 
(which is the default setting for EXCLUDE) silently disables the xInverse
optimization.  This is a feature, but we will keep it undocumented for now
in case we later decide it is a bad idea.

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()).
