With '%', non-ascii worked because the '%' automatically got promoted to
unicode. With format that doesn't happen, which led to encoding errors. This
fix goes back to using %, and adds a test to make sure non-ascii string values
work in iterdump.
Although there is not a regression in Python2, we make the same update here to
keep the code bases in sync.
(The fix for issue 9750 introduced a regression in Python 3 by sorting the row
objects returned by fetchall. But if a row_factory such as sqlite3.Row is
used, the rows may not be sortable (in Python3), which leads to an exception.
The sorting is still a nice idea, so the patch moves the sort into the sql.)

and threading modules
* Add @unittest.skipUnless(threading, ...) to testcases using threads

Avoid also a duplicate connection in some tests: setUp() does already open a

characters. This avoids the common case of something like 'NUMBER(10)' not
being parsed as 'NUMBER', like expected. Also corrected the docs about
converter names being case-sensitive. They aren't any longer.
