source.py: don't let StopIteration propagate to silence() contextmanager

As per PEP 0479 (https://www.python.org/dev/peps/pep-0479/),
StopIteration thrown in context managers are not valid starting from
Python 3.7.

_platform/linux.py: Move get_bwrap_version into _site.py

It's inconvenient to have to create a Linux platform to parse the bwrap version
and we want to get the version in a consistent manner.

buildstream/sandbox/_sandboxbwrap.py: Distinguish sandbox failure from command failure

If `bwrap` fails to set up the sandbox and start the payload command
it won't write an exit-code in --json-status-fd,
so we can report if it was a sandboxing failure if we don't get exit-code status
and a payload command failure if we do and it's non-zero.

Closes https://gitlab.com/BuildStream/buildstream/issues/286

Add cli main and user config option for 'pull-buildtrees' context.

_context.py: Add pull_buildtrees global user context, the default
of which is set to False via the addition of pull-buildtrees to
userconfig.yaml cache group.

_frontend/app.py & cli.py: Add --pull-buildtrees as a bst main
option, which when passed will override the default or user defined
context for pull_buildtrees.

tests/completions/completions.py: Update for the added flag.

Don't pull artifact build trees by default.

The addition of cached build trees being included in element
artifacts has led to mostly redundant download overheads when
pulling from a remote artifact server. As such the default behaviour
of pull shouldn't fetch the build tree object if available.

element.py: extend relevant pull logic for specified subdir
consideration and ensure push logic does not lead to partial
artifact pushes. Change assumption that the buildtree can be
extracted if artifact is cached. __cached_buildtree() and
__pull_directories() helpers added.

_artifactcache/: artifactcache.py & cascache.py inclusion of
helper functions for subdir artifact checking & fetching, fetch
logic extended to only pull required artifact directories.
extract & checkout updated to handle full/partial operation.

tests/: addition of integration test pullbuildtrees.py,
buildtrees.py adapted cli options, testutils/artifactshare.py
has_artifact changed to return artifact digest on true condition.

plugins/sources/pip.py: also look for python version named "python"

In some virtual environments, we might not have the binary with the
exact python version, which would lead the current pip plugin to
fail to find a working pip version.

This adds "python" at the start of the list of valid python versions

tests/frontend/buildtrack.py: check for success after invocation

Previously the result of the first call in test_build_track was not
checked to be successful, which would lead to potential erros later on
that were hard to debug.

Fix os.rename in git source element to correctly handle error codes

According to the documentation
(https://www.unix.com/man-page/POSIX/3posix/rename/), when the directory
already is there, either EEXIST or ENOTEMPTY could be thrown.

Previously only ENOTEMPTY was checked.

Done:
  - Separated the move into its own function
  - Check for both errors
  - Create unit tests for it, covering most test cases

Extract atomic move function to utils.py

Moving atomically a file/directory can be tricky since different
errors might be raised for the same underlying problem.

Having a utility function to reduce this discrepancies will help
in ensuring we have correct behavior

buildstream/_pipeline.py: Simplify error message for assert_consistent()

Currently, `Pipeline.assert_consistent()` prints an error message like
the one below when certain elements have inconsistent sources:

```
...
      Element: hello.bst is inconsistent
        Source tar source at hello.bst [line 16 column 2] is missing ref
...
```

Drop the word "Source" from the beginning of the message as
"Source <source-kind> source ..." is kind of awkward to read.

Add `bst source-checkout` command

As discussed in
https://mail.gnome.org/archives/buildstream-list/2018-September/msg00064.html,
add `bst source-checkout` command. This will allow users to checkout
sources for a given target.

* _frontend/cli.py: Add source-checkout command
* _pipeline.py: Add assert_sources_cached() method
* _stream.py: Add source_checkout method, abstract out
  __check_location_writable() method that used to part of checkout()

Don't cache sandbox errors

Sandbox errors (like missing host tools) are dependent on the host
system and rarely on what is actually done.

It is therefore better to not cache them as they are subject to
change between two runs.

Also add test to ensure sandbox failure are not cached

element.py: Only cache on element error or success

Reverse the way we were handling caching by only caching
when we know it's a problem with the build or the build is a
success in order not to cache transient errors.

_context: refactor, extract _node_get_option_str

Use a new helper function to simplify working with nodes that can only

In later work we can see if this function would be useful elsewhere, and
could be added to '_yaml.py'.

Add prompt.auto-init buildstream.conf option

Provide an option in buildstream.conf to disable the 'Would you like to
...' prompt when we cannot resolve a project.

Some users prefer not to be interrupted by such prompts, so pave the way
to creating options to disable all those that might get in the way.

Follow the example of the advice.* options 'git-config', and create a
namespace for these UI options grouped by behaviour, rather than an
over-reaching 'ui.*' namespace. In later work perhaps we'll also add
'advice.*' options.

Add a NEWS item for this.
