Added new option --fixed-size to wks. The option can be used to indicate
the exact size of a partition. The option cannot be added together with
--size, in which case an error will be raised. Other options that
influence automatic partition size (--extra-space, --overhead-factor),
if specifiec along with --fixed-size, will raise an error.
If it partition data is larger than the amount of space specified with
--fixed-size option wic will raise an error.

It turns out that dd's conv=sparse doesn't look at the file extents, but simply
checks if a "block" is all zero. If the block of zero was meaningful it gets
lost and if the image is subsequently written to media using a sparse-aware
writer then the block of zeros won't be written at all.

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.

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.

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.
