Btrfs progs release 4.2

[David Sterba <dsterba@suse.cz>]

Hi,

here goes anoher release. There are many cleanups/bugfixes and just a handful
of user-visible improvements.

Thanks to all contributors!

enhancements:
  * mkfs: do not create extra single chunks on multiple devices
  * resize: try to guess the minimal size, 'inspect min-dev-size'
  * qgroup assign: add option to schedule rescan
  * chunk-recover: be more verbose about the scanning process

fixes:
  * check:
    * find stripes crossing stripe boundary -- created by convert
    * print correct range for file hole when there are no extents
      and learn how to fix it
  * replace: more sanity checks
  * convert: concurrency fixes related to reporting progress
  * find-root: option -a will not skip the current root anymore
  * subvol list: fix occasional crash
  * do not create stripes crossing stripe boundary

build:
 * fixes for musl libc
 * preliminary support for android (not working yet, more code changes needed)
 * new EXTRA_CFLAGS and EXTRA_LDFLAGS

other:
 * lots of cleanups
 * tests: lots of updates, new tests, framework improvements
 * documentation updates
 * debugging: print-tree shows stripe length
