This patch makes the back reference system to explicit record the
location of parent node for all types of extents. The location of
parent node is placed into the offset field of backref key. Every
time a tree block is balanced, the back references for the affected
lower level extents are updated.

This patch corrects open-coded inode_map iteration, which happens to be
illegal in new libext2fs due to inode_map being private, causing warning,
which becomes a compile error.

This patch improves converter's allocator and fixes a bug in data relocation
function. The new allocator caches free blocks as Btrfs's default allocator.
In testing here, the user CPU time reduced to half of the original when
checksum and small file packing was disabled. This patch also enlarges the
size of block groups created by the converter.

The main changes in this patch are adding chunk handing and data relocation
ability. In the last step of conversion, the converter relocates data in system
chunk and move chunk tree into system chunk. In the rollback process, the
converter remove chunk tree from system chunk and copy data back.

Hello,
This patch fixes two newly found bugs in the converter. The important
one is in create_ext2_image, sub-volume root directory's size not
properly updated after creating the ext2 image file. The other one is
a small bug in xattr support codes. In addition to the fixes, this
patch moves the 'if mounted' check to main() function.
Regards
YZ

This patch adds readonly inode flag support. A file with this flag
can't be modified, but can be deleted.

This patch adds rollback support for the converter, the converter can
roll back a conversion if the image file haven't been modified. In
addition, I rearrange some codes in convert.c and add a few comments.

run make convert to build it, the program is named btrfs-convert and is
not installed by default.
