Update borgbackup to 1.0.11.
(I am not 100% sure about the PLIST changes, I'd appreciate for someone
to verify.)

Version 1.0.11 (2017-07-21)
---------------------------

Bug fixes:

- use limited unpacker for outer key (security precaution), #2174
- fix paperkey import bug

Other changes:

- change --checkpoint-interval default from 600s to 1800s, #2841.
  this improves efficiency for big repositories a lot.
- docs: fix OpenSUSE command and add OpenSUSE section
- tests: add tests for split_lstring and paperkey
- vagrant:

  - fix openbsd shell
  - backport cpu/ram setup from master
  - add stretch64 VM

Version 1.0.11rc1 (2017-06-27)
------------------------------

Bug fixes:

- performance: rebuild hashtable if we have too few empty buckets, #2246.
  this fixes some sporadic, but severe performance breakdowns.
- Archive: allocate zeros when needed, #2308
  fixes huge memory usage of mount (8 MiB × number of archives)
- IPv6 address support
  also: Location: more informative exception when parsing fails
- borg single-file binary: use pyinstaller v3.2.1, #2396
  this fixes that the prelink cronjob on some distros kills the
  borg binary by stripping away parts of it.
- extract:

  - warning for unextracted big extended attributes, #2258
  - also create parent dir for device files, if needed.
  - don't write to disk with --stdout, #2645
- archive check: detect and fix missing all-zero replacement chunks, #2180
- fix (de)compression exceptions, #2224 #2221
- files cache: update inode number, #2226
- borg rpc: use limited msgpack.Unpacker (security precaution), #2139
- Manifest: use limited msgpack.Unpacker (security precaution), #2175
- Location: accept //servername/share/path
- fix ChunkIndex.__contains__ assertion  for big-endian archs (harmless)
- create: handle BackupOSError on a per-path level in one spot
- fix error msg, there is no --keep-last in borg 1.0.x, #2282
- clamp (nano)second values to unproblematic range, #2304
- fuse / borg mount:

  - fix st_blocks to be an integer (not float) value
  - fix negative uid/gid crash (they could come into archives e.g. when
    backing up external drives under cygwin), #2674
  - fix crash if empty (None) xattr is read
  - do pre-mount checks before opening repository
  - check llfuse is installed before asking for passphrase
- borg rename: expand placeholders, #2386
- borg serve: fix forced command lines containing BORG_ env vars
- fix error msg, it is --keep-within, not --within
- fix borg key/debug/benchmark crashing without subcommand, #2240
- chunker: fix invalid use of types, don't do uint32_t >> 32
- document follow_symlinks requirements, check libc, #2507

New features:

- added BORG_PASSCOMMAND environment variable, #2573
- add minimal version of in repository mandatory feature flags, #2134

  This should allow us to make sure older borg versions can be cleanly
  prevented from doing operations that are no longer safe because of
  repository format evolution. This allows more fine grained control than
  just incrementing the manifest version. So for example a change that
  still allows new archives to be created but would corrupt the repository
  when an old version tries to delete an archive or check the repository
  would add the new feature to the check and delete set but leave it out
  of the write set.
- borg delete --force --force to delete severely corrupted archives, #1975

Other changes:

- embrace y2038 issue to support 32bit platforms
- be more clear that this is a "beyond repair" case, #2427
- key file names: limit to 100 characters and remove colons from host name
- upgrade FUSE for macOS to 3.5.8, #2346
- split up parsing and filtering for --keep-within, better error message, #2610
- docs:

  - fix caskroom link, #2299
  - address SSH batch mode, #2202 #2270
  - improve remote-path description
  - document snapshot usage, #2178
  - document relative path usage, #1868

  - added FAQ section about backing up root partition
  - add bountysource badge, #2558
  - create empty docs.txt reequirements, #2694
  - README: how to help the project
  - note -v/--verbose requirement on affected options, #2542
  - document borg init behaviour via append-only borg serve, #2440
  - be clear about what buzhash is used for (chunking) and want it is not
    used for (deduplication)- also say already in the readme that we use a
    cryptohash for dedupe, so people don't worry, #2390
  - add hint about chunker params to borg upgrade docs, #2421
  - clarify borg upgrade docs, #2436
  - quickstart: delete problematic BORG_PASSPRHASE use, #2623

  - travis:

    - enhance travis setuptools_scm situation
    - install fakeroot for Linux
  - add test for borg delete --force
  - enable remote tests on cygwin (the cygwin issue that caused these tests
    to break was fixed in cygwin at least since cygwin 2.8, maybe even since
    2.7.0).
  - remove skipping the noatime tests on GNU/Hurd, #2710
  - fix borg import issue, add comment, #2718
  - include attic.tar.gz when installing the package
    also: add include_package_data=True

Version 1.0.10 (2017-02-13)
---------------------------

Bug fixes:

- Manifest timestamps are now monotonically increasing,
  this fixes issues when the system clock jumps backwards
  or is set inconsistently across computers accessing the same repository, #2115
- Fixed testing regression in 1.0.10rc1 that lead to a hard dependency on
  py.test >= 3.0, #2112

New features:

- "key export" can now generate a printable HTML page with both a QR code and
  a human-readable "paperkey" representation (and custom text) through the
  ``--qr-html`` option.

  The same functionality is also available through `paperkey.html <paperkey.html>`_,
  which is the same HTML page generated by ``--qr-html``. It works with existing
  "key export" files and key files.

Other changes:

- docs:

  - language clarification - "borg create --one-file-system" option does not respect
    mount points, but considers different file systems instead, #2141
- setup.py: build_api: sort file list for determinism

Version 1.0.10rc1 (2017-01-29)

Bug fixes:

- borg serve: fix transmission data loss of pipe writes, #1268
  This affects only the cygwin platform (not Linux, BSD, OS X).
- Avoid triggering an ObjectiveFS bug in xattr retrieval, #1992
- When running out of buffer memory when reading xattrs, only skip the
  current file, #1993
- Fixed "borg upgrade --tam" crashing with unencrypted repositories. Since
  :ref:`the issue <tam_vuln>` is not relevant for unencrypted repositories,
  it now does nothing and prints an error, #1981.
- Fixed change-passphrase crashing with unencrypted repositories, #1978
- Fixed "borg check repo::archive" indicating success if "archive" does not exist, #1997
- borg check: print non-exit-code warning if --last or --prefix aren't fulfilled
- fix bad parsing of wrong repo location syntax
- create: don't create hard link refs to failed files,
  mount: handle invalid hard link refs, #2092
- detect mingw byte order, #2073
- creating a new segment: use "xb" mode, #2099
- mount: umount on SIGINT/^C when in foreground, #2082

Other changes:

- xattr: ignore empty names returned by llistxattr(2) et al
- Enable the fault handler: install handlers for the SIGSEGV, SIGFPE, SIGABRT,
  SIGBUS and SIGILL signals to dump the Python traceback.
- Also print a traceback on SIGUSR2.
- borg change-passphrase: print key location (simplify making a backup of it)
- officially support Python 3.6 (setup.py: add Python 3.6 qualifier)
- tests:

  - vagrant / travis / tox: add Python 3.6 based testing
  - vagrant: fix openbsd repo, #2042
