For sqlite3_win32_is_nt(), assume WinRT is NT-based. (check-in: 2f59e71fbf user: mistachkin tags: winrt)

Fix a faulty assert() statement. Add comments to clarify the behavior of the sqlite3OpenTableAndIndices() routine in insert.c. Add test cases to verify that the assert() statement is not firing inappropriately. Ticket [369d57fb8e5ccdff06f1]. (check-in: 7029b3404d user: drh tags: trunk)
