To: devel; +Cc: jiewen.yao, jordan.l.justen, kraxel, sebastien.boeuf
From: Sebastien Boeuf <sebastien.boeuf@intel.com>
Don't make the package Qemu centric so that we can introduce some
alternative support for other VMMs not using the fw_cfg mechanism.
This patch is purely about renaming existing files with no functional
change.

> The goal is to allow the same binary to be used either by QEMU or Cloud
> Hypervisor, using the Cloud Hypervisor way as a fallback if the fw_cfg
