Log Message:
py-borgbackup: update to 1.1.16.

Version 1.1.16 (2021-03-23)
---------------------------

- 1.1.15 drops python 3.4 support, minimum requirement is 3.5 now.

Fixes:

- setup.py: add special openssl prefix for Apple M1 compatibility
- do not recurse into duplicate roots, #5603
- remove empty shadowed_segments lists, #5275, #5614
- fix libpython load error when borg fat binary / dir-based binary is invoked
  via a symlink by upgrading pyinstaller to v4.2, #5688
- config: accept non-int value (like 500M or 100G) for max_segment_size or
  storage_quota, #5639.
  please note: when setting a non-int value for this in a repo config,
  using the repo will require borg >= 1.1.16.

New features:

- bundled msgpack: drop support for old buffer protocol to support Python 3.10
- verbose files cache logging via --debug-topic=files_cache, #5659.
  Use this if you suspect that borg does not detect unmodified files as expected.
- create/extract: add --noxattrs and --noacls option, #3955.
  when given with borg create, borg will not get xattrs / ACLs from input files
  (and thus, it will not archive xattrs / ACLs). when given with borg extract,
  borg will not read xattrs / ACLs from archive and will not set xattrs / ACLs
  on extracted files.
- diff: add --json-lines option, #3765
- check: debug log segment filename
- borg debug dump-hints

Other changes:

- Tab completion support for additional archives for 'borg delete'
- repository: deduplicate code of put and delete, no functional change
- tests: fix result order issue (sporadic test failure on openindiana)
- vagrant:

  - upgrade pyinstaller to v4.2, #5671
  - avoid grub-install asking interactively for device
  - remove the xenial box
  - update freebsd box to 12.1
- docs:

  - update macOS install instructions, #5677
  - use macFUSE (not osxfuse) for Apple M1 compatibility
  - update docs for dev environment installation instructions, #5643
  - fix grammar in faq
  - recomend running tests only on installed versions for setup
  - add link back to git-installation
  - remove /var/cache exclusion in example commands, #5625.
    This is generally a poor idea and shouldn't be promoted through examples.
  - add repology.org badge with current packaging status
  - explain hash collision
  - add unsafe workaround to use an old repo copy, #5722
