  artifactcache: fix oversight
  
  We want to check if some file is already cached here, not the parent
  directory.

  artifactcache: improve _create_tree()
  
  * Rename it to _commit_directory() because… it is what it does; and
    also for symmetry with _fetch_directory().
  * Rename digest to dir_digest to make it clear this is a digest for a
    directory. A following commit will also reuse the same variable name
  * Document method.

  artifactcache: improve _fetch_directory()
  
  * Rename tree to dir_digest to make it clear this is a Digest object,
    and not a Tree object.
  * Add documentation

  buildstream/_frontend/complete.py: Added missing click license compliance
  
  Somehow I missed this when originally forking the file from the click
  library, now noticing that we should have followed what was written
  in: https://github.com/pallets/click/blob/master/LICENSE

  Bump Artifact Version
  
  Since we now set PWD in the environment of builds
  existing builds may behave differently so must cache differently now.

  Cachekey update helper: Document ensuring . in PYTHONPATH
  
  The current directory isn't always in the python module search path,
  so we have to ensure it is for the script to work.
  
  Strictly speaking, the user may already have a modified PYTHONPATH
  at which point PYTHONPATH=".${PYTHONPATH+:$PYTHONPATH}" is necessary,
  but it's probably premature to overcomplicate the documentation like that
  before we discover it's a problem.

  _project.py: Fix option resolution in element & source overrides
  
  This ensures that option expressions are resolved in the project
  level overrides before attempting to composite them on the instantiated
  elements. Seems this is a regression from introducing the include
  directive.
  
  This fixes issue #658

  _artifactcache/artifactcache.py: Ensure no double-setup of remotes
  
  Since ArtifactCache.setup_remotes() can be expensive and should only
  happen once, this commit will assert() if it is called a second time
  on an artifact cache instance.

  tests/artifactcache/pull.py: Do not double-initialize remotes
  
  The initialization of remotes is done by ArtifactCache.setup_remotes()
  and as such it was wrong for these tests to be calling
  CASCache.initialize_remotes() a second time.

  sandbox/_sandboxremote.py: Acquire artifact cache via Platform
  
  The SandboxRemote used to construct its own CASCache which was
  considered dangerous.  This patch replaces that with acquisition of
  the cache via the Platform singleton, hopefully eliminating issues
  from having more than one artifact cache object in a single process.

  _artifactcache/artifactcache.py: Error out gracefully when push remote is mal-specified
  
  When configuring a push remote and specifying either the client-cert
  or the client-key, then both must be specified. This ensures we
  get an informative error instead of a stack trace and BUG.
  
  Fixes issue #625

  without client-key, or the inverse.

  fuse: Report the correct device number for devices
  
  This fixes all devices being mapped to the non-existant device 0,
  which prevents being able to use even safe devices like /dev/null
  through the hardlinks FUSE layer.

  FUSE: Mount with -odev in chroot sandbox
  
  This is needed to permit access to the device nodes added to /dev
  on Linux when FUSE is used as root.
  
  The chroot sandbox only works with all privileges,
  so there's no explicit check for being root
  or having the appropriate capabilities.
  
  A check for whether it's running as root isn't needed on Linux with bubblewrap
  because /dev or its devices are mounted on top of the FUSE layer,
  so device nodes are accessed directly rather than through the FUSE layer.

  Rework Skipped usage
  
  The SKIPPED message type is now used to indicate the end of a task which
  was successful without having to perform the given task.
  
  This overhauls the use of `Queue.done()` and therefore queues do not
  need to provide a processed/skipped return value from `done()`. Instead
  this is replaced with the action of raising a `SkipJob` exception from
  within `Queue.process()`.

  tests.py: Test skip on push
  
  Adds a test to ensure that BuildStream alerts the user of a skipped push
  when the remote already has the artifact cached.

  element.py: Remove redundant timed_activity
  
  This removes the timed_activity for an element _push action. This is
  unnecessary as the job is already being timed elsewhere.

  cascache.py: Move push/pull messaging to cascache
  
  Pulled/Pushed messages will no longer be produced from within
  element.py, instead they will be produced during CasCache push() and
  pull() appropriately.
  
  Message consistency has also been improved.

  cascache.py: Modify messaging API calls
  
  Both pulling and pushing INFO messages are now status messages.
  
  Calls to the messaging API through `self.context.message()` have now
  been switched to `element.info`.

  _frontend/status.py: Completely remove the blessings dependency from BuildStream
  
  This actually improves reliability of the status bar because we
  now disable it completely in the case that not all of the terminal
  escape sequences are supported on the given terminal.
  
  This replaces the few functions we were using, to move the cursor
  up one line, move it to the beginning of the line, and to clear a
  line, with low level functions provided by the curses module in
  the standard library.
  
  This change makes it easier for downstream distro package maintainers
  to package BuildStream, particularly on Fedora.
  
  Asides from changing _frontend/status.py, this commit includes the
  following changes:
  
    * _frontend/app.py: Use python isatty() function to determine if
                        we are connected to a tty, instead of relying
  		      on blessings.
  
    * setup.py: Remove the dependency on blessings.

  element.py: Remove early warning and check directory is not None
  
  The check for directory should have always been here. The early warning
  test doesn't work for `bst checkout` because caches haven't been configured
  at the point of the test, so I've had to remove it.
