2016-05-06	wic: add sparse_copy API	Ed Bartosh	1
	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.

2016-05-06	wic: add FIEMAP and SEEK_HOLE / SEEK_DATA APIs	Ed Bartosh	1
	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).
