Renamed partition images into <final image>.p<partition number>
This should make output directory look more organized and easier

Switched debug level to 'normal' to prevent huge 'bitbake -e'
output to go into wic debug output. This should help to make
wic debug info much more clean and easier to read.

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.

Set type GUID and UUID for partition using sgdisk utility.
Type GUID can be specified for partition in .wks with
--part-type option.
UUID is generated when --use-uuid option is specified for
partition.

Specifying partition type(GUID) makes sense for gpt partition table.
Current code checks if part-type is specified and throws exception
if it is. This makes sense to do only for msdos partition table.

All wic exceptions are now inherited from new base exception
class WicError. It makes them easy to maintain and catch.
Processing of exceptions is done this way:
Known wic exceptions cause wic to print error message to stdout.
Unknown exceptions are not catched anymore and produce standard
python traceback.

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.

Used exec_native_cmd instead of find_binary_path to run parted.
Got rid of find_binary_path as it's not used anywhere else.
There are several tools wic is trying to find not only in sysroot,
but also in host root. Parted is a special as on some distros it's
installed in /usr/sbin, which is not in the user's PATH. This makes
wic to fail with error "External command 'parted' not found, exiting."

For some architectures it is necessary to reserve space on disk without
it being present in the partition table.
For example, u-boot on i.mx is placed at an offset of 1kB on the sdcard.
While it would be possible to create a partition at that offset and
place u-boot there, it would then be necessary to update the default
u-boot environment to use partition 2 on the mmc instead of partition 1.

Use kB instead of MB for the partition size to get a better granularity.
This is needed on some SoC (i.mx, omap) where it is necessary to create
partitions as small as 64kB.
Keep the backward compatibility by assuming MB when no unit is provided.

The patch fixes an issue in laying out extended and logical partitions
by wic. The original code produced disk images in which the size 3rd
partition as described in MBR was incorrect. Depending on the type of
file system used for that partition and size of the partition, it would
be impossible to mount the partition correctly. For instance, kickstart
file in which the 3rd partition had size of 1GB and used ext4 fs, would
result in an image with an umountable partition. The root cause is
reservation of sectors for EBR through stealing of last sector from the
last primary partition.

To support yocto on systems with python3 as default version, scripts
should use /usr/bin/env python in the shebang, as this allows the use of
a fake env to mimic python2 as default version.
This patch simply replaces occurrences of #!/usr/bin/python with
#!/usr/bin/env python and was done with this oneliner:
git grep -lE '^#!/usr/bin/python' | xargs \
sed -i 's|/usr/bin/python|/usr/bin/env python|'

When creating partitions sized to given rootfs directories, filesystem
creation could fail in cases where the calculated target partition
size was too small to contain the filesystem created using mkfs. This
occurred in particular when creating partitions to contain very large
filesystems such as those containing sdk image artifacts.
This same limition is present in the oe-core image creation classes,
which can be readily see by changing IMAGE_OVERHEAD_FACTOR from the
default 1.3 to 1.0 and building a sato-sdk image.
It should be possible to calculate required sizes exactly given the
source rootfs and target filesystem types, but for now, to address the
specific problem users are hitting in such situations, we'll just do
exactly what oe-core does and define and use an IMAGE_OVERHEAD_FACTOR
or 1.3 in those cases.
Fixes [YOCTO #6863].

In order to make up for space loss due to overhead located before the
first partition, same amount of bytes was extracted from the first
partition's size. This leads to unexpected change of first partition's
size, and is not matched by similar adjustment at the time the partition
image is generated. Thus it is possible that the first partition may
partially overwrite contents of the following partition, as the
partition image is larger than the allocated space.
This is also problematic on certain platforms such as OMAP, where the
first partition is required for have an even number of
sectors (typically already expressed by --size in kickstart
file). Subtracting an odd number of sectors lost for overhead, leads to
an odd number of sectors assigned for partition, preventing the board,
such as beaglebone, from booting correctly.
