[PATCH v4 0/2] btrfs: Reformat and make btrfs_tree.h self-contained

[Qu Wenruo <wqu@suse.com>]

Before this patch, although btrfs_tree.h contains most of needed
structures for one to read on-disk btrfs data, it still has some missing
parts:
- Missing some structures and flags
  Like btrfs_super_block, and BTRFS_INODE_* flags

- Not self-contained
  It still needs to include <linux/btrfs.h>

- Uses old/deprecated comment style

This patchset will first move on-disk structure definition to
btrfs_tree.h first, making it self-contained.

Then reformat btrfs_tree.h to make it follow current comment style.

This patchset is mostly designed for incoming projects like U-boot to
share the kernel definitions more easily.

Changelog:
v2:
- Add the reason why we move the code

v3:
- Move more flags/enum shared with ioctl to btrfs_btree.h
  This makes ioctl header to rely on btree_btree.h.
  But this makes btrfs_tree.h completely self-consistent.
  This problem is mostly exposed when syncing the header to btrfs-progs.

v4:
- Update btrfs_tree.h comment style
- Update btrfs_tree.h header define line
- Move enum btrfs_compression_type to btrfs_tree.h
