By returning early when no upgrade device can be found and handling the
SAVE_PARTITIONS=0 case differently, we can get rid of two levels of if.

The staged sysupgrade will prevent us from using ask_bool in
platform_do_upgrade; therefore, the check is moved to platform_check_image.

Even when the disk uses 4k blocks, the partition table still uses units
of 512 byte sectors. Always use ibs=512 for the offsets

Generalize the partition discovery in sysupgrade in order to fix sysupgrade
and config backup/recovery on MMC block devices which use a different naming
scheme compared to mtdblock or sd* devices.
The change also adds the find applet to the ramdisk utilities so that upgrade
code can rely on it.
The commit is based on the initial submission by Russell Senior at
http://patchwork.ozlabs.org/patch/625440/ .

Virtual disk devices in a Xen virtual machine (DomU) can be /dev/xvda,
/dev/xvdb and so on with partitions like /dev/xdva1. Devices named like
this where not considered before. This resulted in a non working
sysupgrade, because the boot partition could not be found.

With this patch sysupgrade will write directly to the partitions
instead of to the main disk. The UUID is copied from the image
to the MBR as well. This prevents the mbr from being completely
overwritten and losing the partition table. The -p option has
been added to maintain the original behavior and overwite the
entire disk with the new image. Tests have been added to ensure
that the image partitions match up with the active partitions.

This changes the x86 image generation to match x86_64, using the PARTUUID for
the rootfs instead of explicitly configuring the device.
It unbreaks KVM with VirtIO, which uses /dev/vda2 instead of /dev/sda2.
Tested in QEMU/KVM with VirtIO, VirtualBox and VMware.

ARGC is a 'C-ism', but not known/valid in shell-syntax - insert the correct
var $# (=number of args) here. under normal conditions this had no impact,
but we should at least correct it. the error was observable like this:
root@box:~ [ -e "/etc/functions.sh" ] && . /etc/functions.sh
root@box:~ [ -e "/lib/functions.sh" ] && . /lib/functions.sh

ash: bad number

Sysupgrade broke on x86 when grub2 superceded grub. This patch
corrects tha magic_word to be expected in grub2 combined images.
