From d8c2c24507c0999240c74c4b85e33e1646d84e7f Mon Sep 17 00:00:00 2001
From: Leah Rowe <leah@libreboot.org>

Subject: vendor.sh: move some functions to vendor/download

they are the functions only used by the download
script, so they don't belong in vendor.sh

an include file should only contain variables and
functions used by multiple main scripts
