Use pxelinux "ipappend" option to choose rootfs source
This fixes the issue described in the first 'netkeys' commit, where the network would need to be available even when it was not used. The "ipappend" option results in a $BOOTIF variable in the initrd environment. This variable is now used to determine whether to wait on the network for a rootfs & keys, or to wait on the boot device becoming available to determine whether it has the keys. That is, there may or may not be a boot device which may or may not have keys and/or rootfs, but we will always know for sure whether it does, therefore there are no races and no waiting on the network unnecessarily. The qemu.sh script was updated to provide the BOOTIF variable when PXE boot is emulated.
