[PATCH 0/7] btrfs-progs: cmds/tune: add set/clear features

[Qu Wenruo <wqu@suse.com>]

This is the first step to convert btrfstune functionality to "btrfs
tune" subcommand group.

For now only binary features, aka set and clear, is supported,
thus uuid and csum change is not yet implemented.
(Both need their own subcommand groups other than set/clear groups)

And even for set/clear, there is some changes to btrfstune:

- Merge seed feature into set/clear
  To enable seeding, just go "btrfs tune set seed <device>".

- All supported features can be checked by "list-all" feature
  Please note that, "btrfs tune set list-all" and
  "btrfs tune clear list-all" will have different output.

  The reason is some fundamental features like no-holes can not be
  disabled.
