ScriptElement does not use Sandbox.get_directory. It works using it
with remote execution.

Fixes #850

It was 'instance-name' in the documentation.

This patch namespaces the test temp directory and the output
coverage report file with the name of the environment under test,
such that separately run tests do not access the same files.

When running tests without tox, directly through setup.py,
then the tmp directory will still be `./tmp`.

  * .gitignore: Added new .coverage-reports/ directory

  * .gitlab-ci.yml: Rely on tox to combine and report coverage, only
    tell tox about the COVERAGE_PREFIX so that results can be namespaced
    by CI job name.

    This change also publishes the sources and final combined `.coverage`
    file in an output gitlab artifact for inspection, and lists some missing
    dependencies to the `coverage` job.

  * tox.ini: Add comments and refactor main [testenv] section so that
    other environments dont inherit too much unrelated cruft.

    Generate the coverate reports in the respective {envtmpdir} so that
    all per-process coverage files are prefixed with a full path, ensuring
    that concurrent runs don't mix reports and addressing concerns
    raised in #844.

    Also implemented new `tox -e coverage` environment to combine
    any found coverage and print a report.

  * .coveragerc: Omit .tox/ directory from coverage stats

Fixes issue #844

Also point out that it is possible to run test environments in
parallel using the `detox` tool.

Allow using detox, and fix/refactor collection of coverage reports

Closes #844

  * Omit versioneer's _version.py

  * Omit our __main__.py which is used only internally for generating
    documentation

.coveragerc: Omit some things which are irrelevant to cover.

Accept common architecture aliases for arch options instead of only
accepting the canonicalized, OS-independent architecture name. This
restores compatibility with existing projects and may simplify option
handling for projects that only target a single OS (and thus, do not
need OS-independent architecture names).

Accept common architecture aliases for the sandbox config for
consistency with arch options.

contributing: fix 'oprtation' and some other typos

See merge request !1055

The algorithm adds elements to a dictionary and then sorts the dictionary
by the discovered depths while recursing - using an OrderedDict is enough
to ensure a stable order.

This fixes `bst show --deps plan ...` reporting different results on
each invocation.

This fixes an aspect of #824

Added a function to report the list of elements which appeared in
a given queue in the order of their first appearance.

For each sample project and expected result order, this test ensures that:

  * bst show --deps plan: Always shows the expected build order.

  * bst source fetch: Always executes in the expected build order.

  * bst build: Always builds in the expected order (disabled).

The build part of the test is currently disabled as the scheduler
seems to be messing with the order even in a `--builders 1` scenario.

Make build plan element list stable

Bump the version of pytest-cov, so that we pick up the fix for
the '--no-cov' option breaking in pytest 4.0:

    https://github.com/pytest-dev/pytest-cov/pull/230

This was the error you would get prior to this version:

    _pytest.warning_types.RemovedInPytest4Warning: config.warn has been
    deprecated, use warnings.warn instead

Although it says 'deprecated', it did result in
termination with stack trace.

Minor correction, looks like we're not observing this queue
otherwise we'd be seeing crashes.
