[PATCH 0/9] btrfs-progs: image: Data dump support, restore optimization and small fixes

[Qu Wenruo <wqu@suse.com>]

This patchset can be fetched from github:
https://github.com/adam900710/btrfs-progs/tree/image_data_dump
Which is based on v5.1 tag.

This patchset contains the following main features:
- various small fixes for btrfs-image
  From indent misalign, SZ_* cleanup to too many core cores causing
  btrfs-image crash.

- btrfs-image dump support 
  This introduce a new option -d to dump data.
  Due to item size limit, we have to enlarge the existing limit from
  256K (enough for tree blocks, but not enough for free space cache) to
  256M.
  This change will cause incompatibility, thus we have to introduce a
  new magic as version. While keeping all other on-disk format the same.

- btrfs-image restore optimization
  This will speed up chunk item search during restore.
