Btrfs progs pre-release 4.15-rc1

[David Sterba <dsterba@suse.com>]

Hi,

a pre-release has been tagged.

The only significant change is removing the custom chunk allocator from mkfs
for the --rootdir option.

ETA for 4.15 is in +2 days (2018-02-02).

Changes:

* mkfs --rootdir reworked, does not minimize the final image but can be still
  done using a new option --shrink
* fix allocation of system chunk, don't allocate from the reserved area
* other
  * new and updated tests
  * cleanups, refactoring
  * doc updates
