* Add new functions to communicator helper to return the user, password, host, based on the communicator used.
This implementation can help then generalize the provisioeners later on.
* Update null builder checks to utilize the new functions and check for ANY hostname or user or password
* Update builder to user any hostname
When debugging a build (or maintaining an existing packer template), teach `packer build -debug` how to step through individual `boot_command`s in order to triage the packer template.
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.
