bd7d6d45d4 btrfs-progs: Improvement for making btrfs image from source directory.
* Initialize ret in btrfs_csum_file_block
* Do not abort when xattr is not supported in the source directory
* Remove size limitation of 256M
* Alloc data chunk in a smaller size (8M) to make btrfs image smaller
* Let user specify the btrfs image name
Depends on below patch from samsung guys:

'ret' value was not initialized for 'found' branch.

The same fix sits in kernel:

0d53b212d8 Btrfs: update converter for the new disk format
This patch updates the ext3 to btrfs converter for the new
disk format. This mainly involves changing the convert's
data relocation and free space management code. This patch
also ports some functions from kernel module to btrfs-progs.
Thank you,

1148e55804 btrfs-progs: support for different csum algorithims
This is the btrfs-progs version of the patch to add the ability to have
different csum algorithims.  Note I didn't change the image maker since it
seemed a bit more complicated than just changing some stuff around so I will let
Yan take care of that.

Everything else was converted and for now a mkfs just
sets the type to be BTRFS_CSUM_TYPE_CRC32.

aa62e84c84 Btrfs image tool
This patch adds btrfs image tool. The image tool is
a debugging tool that creates/restores btrfs metadump
image.

857e9a2a63 btrfs-progs: Fix printf format casting errors
We get lots of warnings of the flavor:

utils.c:441: warning: format '%Lu' expects type 'long long unsigned int' but argument 2 has type 'u64'

And thanks to -Werror, the build fails. Clean up these printfs
by properly casting the arg to the format specified.
