SD image file was 4G in size but actually the rootfs partition was only
60MB (ex.: rpi-basic-image).
The image file size is not fixed anymore but calculated inside this
class. In this way we will setup the partition for rootfs to fit the
ext file used as SDIMG_ROOTFS. By default the free space is calculated
with IMAGE_OVERHEAD_FACTOR which is by default 1.3. If more free space
is needed this can be overwritten.
IMAGE_ROOTFS_ALIGNMENT set at 4096. This should be the best value for a
SD card.

When burning the rootfs partition we use dd if rootfs file is not
compressed and xzcat piped with dd if rootfs file is a .xz file.

${KERNEL_IMAGETYPE} symlink was introduced after denzil so we use
${KERNEL_IMAGETYPE}-${MACHINE} to be able to satisfy the existence in denzil and master
as well.

Instead of being inherited by a specific image recipe, this class can
now be inherited globally in the machine configuration, allowing it to
be used with any image. This means we can remove "inherit image", and
we can also remove the IMAGE_FSTYPES modification since the machine
config does this already.

This implementation doesn't use loop mounts, it uses mcopy to copy files to partitions.
The partition creation is done with parted. Because of using these tools the
IMAGE_DEPENDS was modified accordingly.
Added a way of selecting the desired GPU firmware.
Because we don't create the rootfs image but we rely on an already created rootfs
image, the stamp is available only in the boot partition.
By default the class needs an ext3 rootfs image. This is because we don't have yet
a way of generating cmdline.txt in order to pass the partition type to the kernel.
By default ext3 is mounted so we use this fs type until this will be selectable while
generating a cmdline file.
