When debugging a build (or maintaining an existing packer file), teach `packer build -debug` how to step through individual `boot_command`s in order to triage the packer template.
This fixes building `packer` with Go >1.6. From https://golang.org/cmd/link/:
```
-X importpath.name=value
Set the value of the string variable in importpath named name to value.
Note that before Go 1.5 this option took two separate arguments.
Now it takes one argument split on the first = sign.

On Windows, packer's 'file' provisioner fails to copy files/directories that include both a volume identifier (e.g. C:) and spaces in the path.
The root cause of this was found to be embedded single quotes in the 'destination' value, added by the github.com/packer-community/winrmcp/winrmcp project.
This updated winrmcp revision includes the fix to resolve this issue.
This is last merge that will happen from the github.com/Azure/packer-Azure
repository. All development is being over to this repository.
The biggest change in this merge is support for Windows. There are a few other
fixes as well.
* If the user cancels the build, clean up any resources.
* Output a reasonable build artifact.
* Log requests and responses with Azure.
* Support for US Government and the China clouds.
* Support interrupting long running tasks.
* Allow the user to set the image version.
* Device login support.
