Btrfs progs release 4.13.1

[David Sterba <dsterba@suse.com>]

Hi,

btrfs-progs version 4.13.1 have been released.

The ZSTD support has been added, the kernel code will land in 4.14. Now
configure will detect if libzstd is available and will use it. In the future
this will become a mandatory dependency. Please check your distro for libzstd
and ask them to add it eventually. As a fallback, it is and will be possible to
disable zstd detection (and btrfs restore will obviously lack the support).

Changes:
  * image: speed up generating the sanitized names, do not generate unprintable chars
  * completion: add missing commands, better mount point detection
  * restore: add zstd support; libzstd detected automatically, will be
    requested by default in the future, or can be configured out
  * other:
    * misc fixes found by sparse
    * doc enhancements, ioctl manual page started
    * updated and new tests
    * build fixes
