[PATCH v2 1/4] btrfs-progs: Remove btrfs-debug-tree command

[Nikolay Borisov <nborisov@suse.com>]

There is already a replacement in the face of btrfs inspect-internal
dump-tree. And this command is just a simple wrapper around it. Just
remove it and adjust the show-blocks script to call the main btrfs
binary to achieve the same effect.
