Btrfs progs release 4.3

Btrfs progs release 4.3

[David Sterba]

Hi,

the btrfs-progs 4.3 have been released.

There's a notable change in the behaviour of mkfs on devices smaller than 1
GiB. The forced --mixed mode is no more. The resulting filesytem will have a
split data and metadata groups. This may lead to earlier 'no-space' because the
space is reserved for metadata use.

* mkfs
  * mixed mode is not forced for filesystems smaller than 1GiB
  * mixed mode broken with mismatching sectorsize and nodesize, fixed
  * print version info earlier
  * print devices sorted by id
  * do not truncate target image with --rootsize

* fi usage:
  * don't print global block reserve
  * print device id
  * minor output tuning
  * other cleanups

* calc-size:
  * div-by-zero fix on an empty filesystem
  * fix crash

* bugfixes:
  * more superblock sanity checks
  * consistently round size of all devices down to sectorsize
  * misc leak fixes
  * convert: don't try to rollback with a half-deleted ext2_saved subvolume

* other:
  * check: add progress indicator
  * scrub: enahced error message
  * show-super: read superblock from a given offset
  * add README
  * docs: update manual page for mkfs.btrfs, btrfstune, balance, convert and
    inspect-internal
  * build: optional build with more warnings (W=...)
  * build: better support for static checkers
  * build: html output of documentation
  * pretty-print: last_snapshot for root_item
  * pretty-print: stripe dev uuid
  * error reporting wrappers, introduced and example use
  * refactor open_file_or_dir
  * other docs and help updates

* testing:
  * test for nodes crossing stripes
  * test for broken 'subvolume sync'
  * basic tests for mkfs, raid option combinations
  * basic tests for fuzzed images (check)
  * command intrumentation (eg valgrind)
  * print commands if requested
  * add README for tests
