e5d2707924 - Update to 0.11: 
* Introduce *extent scan mode* that scans the extent tree directly. It is the
    new default scan mode.
  * Show estimated data size and expected time to finish scanning in logs and
    status outputs.
  * Smarter dedupe criteria that prevents dedupe operations that save less than
    half the blocks in an extent or require more than 100 copy/dedupe operations
    to free space.
  * Add the new dynamic rate throttling option `--throttle-factor` to estimate
    the rate at which the kernel deletes extents and slow down dedupe requests
    to match this rate.
  * Threads now dynamically redistribute their work so that they can make
    continuous progress without waiting for each other.
  * Remove excessively costly "toxic extent" workarounds yielding up to
    100x–1000x speed boost on some workloads.
  * Coordinate between threads to prevent thrashing during disk reads.
  * Prefetche data into page-cache before dedupe calls.
  * Submit full-extent dedupe operations, avoiding obsolete 16M kernel limits.
  * Reduce the size of `ioctl` buffers, which avoids forcing the kernel to
    evict pages from memory to accommodate large buffers.
  * Limit reference counts for very frequently duplicated data, which avoids
    performance issues in btrfs (even when bees is not running).
  * Use the new `openat2` system call for improved robustness against rename and
    symlink attacks.
  * Use a private mount namespace for isolation even without `systemd`.
  * Recude warning and debug log verbosity.
  * `SIGUSR1` and `SIGUSR2` signals allow bees to be paused and unpaused without
    preventing bees from closing open files and subvols during the pause.
  * It is now safe to locate `$BEESHOME` on filesystems such as XFS that lack
    data flushing on `rename`.
  * Fix 32-bit `ioctl` compatibility for mixed 32/64-bit systems.
  * Detect a `btrfs send` in progress, and wait for it to complete
    automatically. `--workaround-btrfs-send` is no longer necessary when used
    with extent scan mode.
