Btrfs progs pre-release 4.19-rc1

Btrfs progs pre-release 4.19-rc1

[David Sterba]

Hi,

this is a pre-release of btrfs-progs, 4.19-rc1. The version 4.18 was skipped to
keep the time of release close to kernel. The sort-of promise that
'progs version X supports features from kernel X' does not hold for the user
accessible ioctls to list subvolumes. As this is not a critical feature that's
missing, hopefully this is berable.

On the downside this blocked the whole 4.18 release as this is a user interface
change that must be done right on the first try. I don't want to repeat this in
future releases so the kernel/userspace feature parity will be more relaxed.

The 4.19 release is scheduled to this Friday, +4 days (2018-11-02).

Changelog:

* check: support repair of fs with free-space-tree feature
* core:
  * port delayed ref infrastructure from kernel
  * support write to free space tree
* dump-tree: new options for BFS and DFS enumeration of b-trees
* quota: rescan is now done automatically after 'assign'
* btrfstune: incomplete fix to uuid change
* subvol: fix 255 char limit checks
* completion: complete block devices and now regular files too
* docs:
  * ship uncompressed manual pages
  * btrfsck uses a manual page link instead of symlink
* other
  * improved error handling
  * docs
  * new tests
