With many open PRs that could benefit from loading SDKs when needed, instead adding vast amounts of code to RIOTs master, this PR provides the "functions" `$(DOWNLOAD_TO_STDOUT)`, `$(DOWNLOAD_TO_FILE)`, and `$(UNZIP_HERE)`. The first "function" takes one argument, the URL from where to download the content. It is then piped to stdout. To be used e.g. with `tar xz`. The second "function" taken two arguments, the destination file name, and the source URL. If the previous invocation was interrupted, then the download gets continued, if possible. The last "function" takes one argument, the source ZIP file. The file gets extracted into the cwd, so best use this "function" with `cd $(SOME_WHERE) &&`. The clumsy name `$(UNZIP_HERE)` is taken because the program "unzip" takes the environment variable `UNZIP` as the source file, even if another file name was given on the command line. The rationale for that is that the hackers of "unzip" hate their users. Also they sacrifice hamsters to Satan.
