Add BIT column support. (Bug 1468725)
Return BINARY columns as normal strings, not arrays. (Bug 1495765)
Add support for a new VARCHAR type; behaves like other CHAR types.
Defer issuing warnings when using SSCursors. (Bug 1495782)

(Bug 1521274)
Fix problem with callproc() when it is used before execute() (which is
legal). (Bug 1541124)
Fix formatting of datetime.timedelta values. (Bug 1527801)
Fix connect_timeout documentation bug. (Bug 1523883)
Try to fix some memory leaks. I think cursors don't leak any more
but I've had no luck with connections. If you close your connections
you should be fine, even if you don't close your cursors.
Clean up setup.cfg so it doesn't break RPM builds on files which
are no longer included.
Add a test case for warnings for column truncation.
Clean up warnings; was working around the introduced bug that
returned (var)char columns with binary collations as array.
Exposed the column flags (values from constants.FLAG) as
description_flags on the cursor.
* Remove version_info from metadata before calling setup() to avoid
complaints
* Fix cursor.callproc() as good as can be fixed.
* Improve/fix various tests for stored procedures.
