source.py: Bring down since version for source mirroring APIs

Since we have now backported this to `bst-1.2`, the APIs have
been introduced in 1.2 and not 1.4

git.py: Handle concurrent download completions properly

Use os.rename() to rename the cloned temporary repository into
place in the source cache, and issue a STATUS message when discarding
a duplicate clone, in the case where the same repository is cloned
twice in parallel.

The problem with using shutil.move() is that it will create the source
directory in a subdirectory of the destination when the destination
exists, so it's behavior depends on whether the destination exists.

This shutil.move() behavior has so far hidden the race condition
where a duplicate repo is created in a subdirectory, as you need
to have three concurrent downloads of the same repo in order to
trigger the error.

This fixes issue #503

junction-elements.rst: Add missing language specifier to literalinclude

A missing language specifier on a literal include directive results in yaml
being rendered as python code. This commit adds the :language: tag to that
directive.

element.py: Cache the result of checking whether an artifact is cached weakly

Normally we'd only need it in the case of scheduling a weakly cached build,
but to allow caching of failed builds we need to be able to distinguish
between cached successes and cached failures
for both strong and weak cache keys.

To allow other cache lookup codepaths to look up via the weak key
requires changes through the call stack to consult which key to use,
and cache invalidation of the saved state when it changes.

element.py: Add metadata to distinguish between successful and failed builds

This just puts the metadata in place,
we're adding code paths to add failed builds later.

by Richard Maw at 2018-07-31T16:31:36Z

Convert call-sites of Element._cached() that assume success

When we later add cached failures it needs to not treat them as successes.

_frontend/widget.py: Render cached failures differently to successes

d14d8ee2

by Richard Maw at 2018-07-31T16:32:35Z

Cache failed builds

This creates an artifact when element assembly fails too,
and if it's the right kind of exception uses the now-included install directory
similarly to if it had returned successfully.

If there's a failure during install the artifact contains any installed files,
but may contain nothing at all.

_scheduler/queues/buildqueue.py: Skip rebuilding cached failures

This flags up a failure and if run in an interactive prompt
permits the user to attempt a rebuild.

_scheduler/queues: Add failed builds to "done" queue

This allows the scheduler to move jobs from the current queue to the next.

As a result of this change later queues than the build queue
mustn't skip a cached failure, so the logic is specialised to build queues only.

complete.py: Ensure paths get completed from 'element-path'

Element paths should always be completed from the root element folder
defined by the element-path key in project.conf. Fix complete_path() to

Sandbox.py: Rename __root to _root.

This is to allow to allow its use by subclasses.

Since access to get_directories is now blocked for some plugins,
and the subclasses of Sandbox do not have configuration defined
by YAML files, they need another way to get at the root directory.
