Disk operations were spread over DirectPlugin, DiskImage and Image
code making the code hard to understand.
Renamed Image class to PartitionedImage.
Removed DiskImage class.
Moved disk operations to PartitionedImage.
There was an implicit support for multiple disks: if different devices
were specified in .wks file (e.g. --ondisk sda and --ondisk sdb), wic
would theoretically generate multiple images. This is quite confusing
option and the code supporting it was broken for a long time. The same
effect (multiple output images) can be achieved in obvious and clear
way - by using multiple .wks files.
This functionality was removed. PartitionedImage works only with
one image. This makes the code less complex and easier to maintain.

As syslinux module has been recently removed and
serial_consloe_form_kargs became local API in rootfs_pcbios_ext plugin
it should be called without syslinux. prefix.

This module contains singe function serial_console_form_kargs, which
is used only by rootfs_pcbios_ext plugin. Moved it there and removed
syslinux module to make it easy to find and mainain plugin code.

Got rid of get_rootfs and set_rootfs java-like getter and
setter. Renamed rootfs to rootfs_dir to be consistent with
the name of kickstart parameter --rootfs-dir.

Used bootloader.timeout instead of kickstart.get_timeout getter.
Accessing attributes instead of getting them with getters is
more pythonic, shorter and readable. It also more consistent as
most of partition and bootloader attributes are used this way.
This change also takes care of appendLine bootloader attribute:
it's renamed to bootloader.append attribute provided by new parser.

Wic gets bitbake variables by parsing output of 'bitbake -e' command.
This implementation improves this procedure as it runs 'bitbake -e' only
when API is called and does it only once, i.e. in a "lazy" way. As parsing
results are cached 'bitbake -e' is run only once and results are parsed
only once per requested set of variables.
get_bitbake_var became the only API call. It replaces find_artifacts,
find_artifact, find_bitbake_env_lines, get_bitbake_env_lines,
set_bitbake_env_lines and get_line_val calls making API much more clear.

The wic plugin creates a disk image containig one ext2/3/4 partition.
No additional boot partition is required. Syslinux is installed into
the image. The target device is a legacy BIOS PC.
Purpose of this plugin:
Other avaliable plugins create a fat partition for /boot and an ext
partition for rootfs. Current linux-yocto kernel packages are not
compatible with this disk layout. The boot partition is not mounted
by default, hence the kernel is installed into rootfs and not into
boot partition. A kernel update ends up in a bricked device. The old
kernel which is still in boot likely does not even boot with updated
kernel modules from /. Even if the boot partition is mounted during
the kernel update the update will fail. The kernel package installs
a symbolic link which is not supported by the fat partition.
Creating just one ext partition for boot and rootfs solves all issues
related to package based kernel updates on the device.
The plugin depends on syslinux-nomtools a user space installer for
syslinux on ext filesystems.
Thanks to Robert Yang who implemented syslinux-nomtools and supported
the implementation of this plugin.
