Previously, it would only output something like

  ClientException: Object PUT failed <url> 413 Request Entity Too Large
  Your request is too large.

... which is misleading as it implies that Swift simply can't handle
large objects.

With MD5Sum checking being added, a concern was brought up that It was
a change with no possibility of reverting to the old behaviour.
This change adds the flag '--ignore-checksum' to the upload subcommand
allowing the checks to be turned off.

Changed occurrences of the magic string for a null md5 to use a descriptive
constant instead.

Updated Error messages generated when validation fails. They should now be more descriptive
and not output a literal newline sequence.

The chunk looks like nicely containable, but it pushes against the
right edge of the screen annoyingly. This patch _only_ prettifies,
without any observable changes.

Using -l, -d /, or a pseduo folder by itself works fine, but if you
combine all of them, this happens:

[zaitcev@guren s]$ swift list -d / testcont
amazon_lili.jpg
pseudodir/
rin_shibuya_pixiv.jpg
swift-c134855-5a.diff
[zaitcev@guren s]$ swift list -d / -l testcont

The patch is a straightforward fix that assigns expected variables.

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__.

Removes an account stat from the object upload path.
This stat fails when user is not account admin even
though the user may have container ACL permission to
write objects.

Reduces the severity of the CLI output message when
upload fails to create the given container (this is
not an error since the container may exist - the user
just does not have permission to PUT or POST the
container).

Changes the 'swift upload' exit return code from 1 to
0 if container PUT fails but object PUT succeeds.

For segment uploads, makes the attempt to create the
segment container conditional on it not being the same
as the manifest container. This avoids an unnecessary
container PUT.

Fixes another bug that became apparent: with segmented
upload a container HEAD may be attempted to determine
the policy to be used for the segment container. When
this failed the result dict has headers=None which was
causing an exception in the shell result handler.

Add unit tests for object upload/download and container
list with --os-storage-url option.

Added test coverage for --totals.
