8dddce21c4 wic: filemap: Fixed spared_copy skip
This patches removes the empty space in front of the copied file which
was skipped. Without this reduction it's not possible to place a
partition with rawcopy and skip parameter on a desired alignment.

c589aff080 wic: use next builtin instead of .next method
Generators in Python 3 don't have .next method. It's recommended
to use 'next' builtin instead. As it also present in Python >= 2.6
it should make wic code compatible with both Python 2 and Python 3.

5f06463c6c wic: use // operator instead of /
Division operator works differently in Python 3. It results in
float unlike in Python 2, where it results in int.
Explicitly used "floor division" operator instead of 'division'
operator. This should make the code to result in integer under
both pythons.

4b971568e1 wic: add sparse_copy API
In order to make wic images sparse sparse_copy function has been
copied from meta-ostro:
https://github.com/kad/meta-ostro/blob/master/meta-ostro/lib/image-dsk.py
This function uses filemap APIs to copy source sparse file into
destination file preserving sparseness.

The function has been modified to satisfy wic requirements:
parameter 'skip' has been added.

a468d4bc57 wic: add FIEMAP and SEEK_HOLE / SEEK_DATA APIs
In order to make wic images sparse set of APIs has been copied
from bmap-tools project.

filemap.py module is taken from bmap-tools project:
https://github.com/01org/bmap-tools/blob/master/bmaptools/Filemap.py
It implements two ways of get information about file block: FIEMAP
ioctl and the 'SEEK_HOLE / SEEK_DATA' features of the file seek
syscall.

Note that this module will be removed as soon as bmaptool utility
supports copying sparse source file into destination file (this is
already agreed with the maintainer of bmap-tools project).
