[Xen-devel] [PATCH OSSTEST v2 05/19] Refactor pxelinux configuration



The mechanism used to PXE boot can differ depending on the firmware
type. Therefore refactor into Osstest::TestSupport and key off a new
host property "firmware".

Currently supported is "bios" (the default) and "uboot", both of which
use pxelinux.cfg style files.

The default for the firmware property is "bios", hence no change for
any existing system (including those which use uboot, regardless of
whether they are now configured with the firmware proprty or not)
