Fix wrench build on Windows
Merge branch 'master' of https://github.com/juju/juju
Revert "Revert "Merge pull request #530 from ericsnowcurrently/backups-storage""

This reverts commit 68c71ec48f16eac6f8aff2a66496afb148ec95c6.
version: add OSSupportedSeries

OSSupportedSeries returns the supported series
for the specified OS.
Unexpose environs/tools.ToolsLtsSeries
state/api: always "upload" all supported series

UploadTools no longer accepts a "fakeSeries"
parameter; the client just sends all of the
supported series of the same OS as the uploaded
tools. This is to support old API servers.

A separate commit will change the API server
side to disregard the parameter, and compute
the supported series on the server side. We
can deprecate the client side parameter in a
future version.

Also: return a generic error if status code
is not 200. We no longer need to check the
"method not supported" error specifically.
state/apiserver: clone uploaded tools for supported series

Disregard additional series specified by client, and clone
for all supported series of the same OS as the uploaded tools.
cmd/juju: remove redundant code from upgrade-juju

- Ignore/obsolete "--series" as in "juju bootstrap". UploadTools
  now computes the series to send to the API server (for backwards
  compat), and the API server now computes the same.
- Remove old backwards compat code.

Also, change jujud/bootstrap to use new version.OSSupportedSeries.
state: NetworkInterfaces type uses Tags

Return the correctly typed name.Tag implementation from NetworkInterfaces methods.
Bump build number when uploading tools during bootstrap

CI was broken due to expectations of build number
being bumped when we upload tools for bootstrap.
Bumping the build number also makes it more straightforward
to identify tools that have been uploaded vs. official ones.
