Adrien Delorme 9f82b75e57 Use the hashicorp/go-getter to download files
* 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

go-homedir

This is a Go library for detecting the user's home directory without the use of cgo, so the library can be used in cross-compilation environments.

Usage is incredibly simple, just call homedir.Dir() to get the home directory for a user, and homedir.Expand() to expand the ~ in a path to the home directory.

Why not just use os/user? The built-in os/user package requires cgo on Darwin systems. This means that any Go code that uses that package cannot cross compile. But 99% of the time the use for os/user is just to retrieve the home directory, which we can do for the current user without cgo. This library does that, enabling cross-compilation.
