Apsw

=========

Removed tests that checked directly calling VFS read/write with
negative offsets or amounts returns errors. This version of SQLite no
longer returns errors in those circumstances and typically crashes
instead.

Various new constants.

===========

No APSW changes - just a binary rebuild. Windows users are
recommended to upgrade their SQLite version.

===========

Updated tables of functions and pragmas in the :doc:`shell` to match
current SQLite version.

=========

Adjust to different SQLite download URLs

Added SQLITE_CONSTRAINT_* and SQLITE_READONLY_ROLLBACK `extended error
codes <https://www.sqlite.org/c3ref/c_abort_rollback.html>`__

Removed CouchDB virtual table

===========

No APSW changes - binary rebuild to pickup new SQLite version

===========

Use https (SSL) for SQLite web site references (downloads and
documentation links). On some platforms/versions/SSL libraries,
Python's SSL module `doesn't work
<https://www.google.com/webhp?q=python%20ssl%20EOF%20occurred%20in%20violation%20of%20protocol>`__
with the SQLite website so a fallback to http is used - the downloads
still have their checksum verified.
