* removed packer.Cache and references since packer.Cache is never used except in the download step. The download step now uses the new func packer.CachePath(targetPath) for this, the behavior is the same.
* removed download code from packer that was reimplemented into the go-getter library: progress bar, http download restart, checksuming from file, skip already downloaded files, symlinking, make a download cancellable by context.
* on windows if packer is running without symlinking rights and we are getting a local file, the file will be copied instead to avoid errors.
* added unit tests for step_download that are now CI tested on windows, mac & linux.
* files are now downloaded under cache dir `sha1(filename + "?checksum=" + checksum) + file_extension`
* since the output dir is based on the source url and the checksum, when the checksum fails, the file is auto deleted.
* a download file is protected and locked by a file lock,
* updated docs
* updated go modules and vendors
This changeset performs the following:
- Updates `masterzen/winrm` vendor to include change from (https://github.com/masterzen/winrm/pull/73).
- Removes `masterzen/xmlpath` dependency, as it is licensed under the LGPL license.
- Updates `dylanmei/winrmtest` vendor to include change from (https://github.com/dylanmei/winrmtest/pull/4).
- Updates `packer-community/winrmcp` vendor to include the removal of the `masterzen/winrm/winrm` sub-class as a result of the `winrm` CLI tool being removed from the `masterzen/winrm` repository.
- Updates nested dependencies as a result of the above vendor changes.
- Refactors `parallels/driver_9` to use `goxpath` instead of `xmlpath`, as `xmlpath` is licensed under LGPL.
- Adds a basic unit test for the refactor work in `parallels/driver_9` to confirm functionality.
This should completely remove any LGPL licensed dependencies inside of the Packer project.
