Added --uuid option to the configuration of wks parser.

option.

Image file name is not unique for the partitions without label.
This causes image being rewritten and used as a source for all
partitions without label. Wic produces broken or incorrect result
images because of that.
Added wks line number to the image name to make it unique.

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 tries to find plugins in every layer and prints a message
'Plugin dir is not a directory or does not exist' if layer
doesn't have plugin dir. It causes a lot of duplicated
messages in the debug output, which makes it hard to find
useful info there.

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.

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

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."
