WIP Test multiple filesystems with Vagrant

[ThomasWaldmann]

Fixes #1289, continuation from #1359.

Both kernel module and FUSE filesystems are supported.

TODO:

• Filesystems requiring a device
  • ext4
  • XFS
  • btrfs
  • NTFS - implemented, but mode/atime/teardown issues
• Filesystems requiring a server
  • CIFS - implemented, but badly breaks py.test
  • SSHFS - implemented, but atime/teardown issues
• Filesystems requiring neither
  • tmpfs - runs out of memory
• Fix FS specific test issues
  • test_non_ascii_acl failing #1361 - test_non_ascii_acl only failed outside of Vagrant due to übel user missing
  • Tests failing on SSHFS #1362 - tests failing on SSHFS (fixed with Filesystem feature detection and test skipping #1373)
  • Tests failing on ntfs-3g #1363 - tests failing on ntfs-3g (fixed with Filesystem feature detection and test skipping #1373 + Skip mode tests with BORG_TESTS_IGNORE_MODES #1383)
• Platform specific Vagrant testing
  • Linux
    • centos7_64
    • centos6_32
    • centos6_64
    • xenial64
    • trusty64
    • jessie64
    • wheezy32
    • wheezy64
  • OS X
    • darwin64
  • BSD
    • freebsd64
    • openbsd64
    • netbsd64

Notes:

• no fakeroot, everything runs as root

What's the status on this? I see a few unchecked boxes, but no blockers noted. Do we need all boxes checked for a merge?

[ThomasWaldmann]

I am currently rebasing / fixing the conflicts / testing this.

One fundamental thing with this changeset is that it switches vagrant provisioning to be all-root (privileged = true). We get rid of fakeroot by this, but not sure if we run into new problems (besides never being able to run non-root).
