Previously we were trying to test writing bytes in Python 3 using only
native (unicode) string objects. That doesn't test what we thought we
were testing.

This patch fixes downloading files to stdout and modifies
_SwiftReader to operate as an iterator that performs file
checks at the end of iteration as well as a context manager.
File verification checks have been removed from __exit__
and added to __iter__.

This patch adds a SwiftService class that incorporates the high
level logic from swiftclient/shell.py. It also ports shell.py to
use the new class, and updates the code in swiftclient/multithreading.py
to allow the SwiftService to be used for multiple operations whilst
using only one thread pool.

Currently, code that imports swiftclient has to have its own logic for
things like creating large objects, parallel uploads, and parallel
downloads. This patch adds a SwiftService class that makes that
functionality available in Python code as well as through the shell.

There is no testtools.main() at all (this was a
unittest.main() before). Let's remove this unused
and non-working code.

The following code can be used if someone needs
to start tests manually:

    python -m unittest <test_file.py>

Coverage for swiftclient.client is 71% with these tests.

Unit tests have been moved into another subdirectory
to separate them from functional tests.
