Fix stack traces discovered with ^C forceful termination.

  * utils.py:_kill_process_tree(): Ignore NoSuchProcess errors

    These are caused because we issue SIGTERM, and if the process
    has not exited after a timeout, we kill it.

  * _scheduler/jobs/job.py: Stop handling NoSuchProcess errors here
    redundantly, they are already ignored.

It seems that we were ignoring it after sleeping when terminating
tasks from the scheduler... but we were not ignoring it when performing
the same pattern in the `Plugin.call()` -> `utils._call()` path, so
we were still getting these exceptions at termination time from host
tool processes launched by source plugins.

_scheduler/scheduler.py: Make _schedule_jobs() private

This is not used anywhere outside of the Scheduler, currently
only the Scheduler itself is allowed to queue a job at this level.

If the highlevel business logic for automatic queueing of auxiliary
jobs moves to another location, we can make this public again.

_scheduler/scheduler.py: Only run one cache size job at a time

When queuing the special cache management related cleanup and
cache size jobs, we now treat these jobs as special and do the
following:

  * Avoid queueing a cleanup/cache_size job if one is already queued

    We just drop redundantly queued jobs here.

  * Ensure that jobs of this type only run one at a time

    This could have been done with the Resources mechanics,
    however as these special jobs have the same properties and
    are basically owned by the Scheduler, it seemed more straight
    forward to handle the behaviors of these special jobs together.

This fixes issue #753

Scheduler: Introduced JobStatus instead of simple success boolean

This changes the deepest callback from when a Job completes to
propagate a JobStatus value instead of a simple boolean, and updates
all of the effected code paths which used to receive a boolean
to now handle the JobStatus values.

This further improves the situation for issue #753, as now we avoid
queueing cache size jobs for pull jobs which are skipped.

sandbox/sandbox.py: Fix regression of command logging

Since we added batch commands, the batch commands print the
text of the commands directly in the message text, but this is wrong.

The detail string is the appropriate place for text of unknown lengths
(the user can actually configure how many max lines of commands they
want to see in their log), the message text itself should be controlled
and brief enough to avoid text wrapping.

Support running test environments in parallel with `detox`

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

_pipeline.py: Fix the planner to retain the original order when depth sorting

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.

each invocation.

tests/frontend/order.py: Adding tests ensuring stable element processing order

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.

.gitlab-ci.yml: Use newer image for overning aarch tests

During recent reorganizing of `.gitlab-ci.yml` to work with `tox`, seems
like we missed to update the image used by the overnight aarch tests,

conftest.py: Don't use deprecated get_marker() function

Starting from `pytest` version 4.1.0, `Node.get_marker()` has been
removed, and hence our tests break when running with newer versions of
`pytest`. It was deprecated since a while back but it has recently been
removed completely. Use `get_closest_marker()` as a replacement that is
suggested in the changelog, and seems to work fine for our use case.

See https://github.com/pytest-dev/pytest/pull/4564 for more context on
the upstream issue.

One way of verifying this change is that this should fix the recently
added `tests-fedora-update-deps` job, that was failing before due to
this issue.

buildstream/_gitsourcebase.py: Reduce git history for git describe.

Found during #833.

`git rev-list --boundary tag..HEAD` unfortunately gives boundaries
that are deeper than should when there is a merge commit between `tag`
and `HEAD`. The common ancestory of the two parents of the merge is
a boundary instead of the parent of the branch that is not traversed.

`--ancestry-path` fixes this issue by restricting `git` traversing
those branches.

_scheduler: Refactor of queues and resources.

This branch makes the following changes:

  * jobs/job.py: No longer stores any interested resource list

    Jobs are ephemeral again, they only ever exist while they
    are running.

  * queues/queue.py: Revert to only handling lists of elements

    Elements pass through the queues, Queue.harvest_jobs()
    replaces Queue.pop_ready_jobs() and now the Queue stops
    creating jobs as soon as there are not enough resources
    for the job.

    Also removed unused `prepare()` abstract method.

  * queues/buildqueue.py: Adapt the part where we launch a job

    This part needs to be reworked anyway, just touch it up for
    now so that it doesnt break with the surrounding changes.

  * jobs/{cachesize,cleanup}job.py: Expose uniform complete callback

    Allows the scheduler to manage resource deallocation for these
    two job completions as a custom thing, at the same phase
    that the Queues take care of their own resource deallocation.

  * resources.py: No longer has knowledge of the job

    Since jobs are ephemeral, they are not a suitable place
    to store the resource identifiers, these must be provided
    by the callers wherever needed.

    Now the main Resources object is owned by the Scheduler
    but shared with Queues, each take care of managing the
    resources of the jobs they create through the same
    resource API.

  * scheduler.py: Reverted to only creating jobs on demand

    This changes the flow of the scheduler such that whenever
    jobs complete, the queues are interrogated for as many
    jobs which can run at the moment but not more; and this
    completely removes the waiting list.

    For the internal cache management jobs, we handle this
    with a little state instead of having a waiting list
    and only launch when the resources permit it.

By abolishing the scheduler waiting list and creating jobs
on demand, we fix the order of element processing and consequently
fix issue #712.

_artifactcache/artifactcache.py: Rephrase failure message

It was saying "There is not enough space to build the given element.",
this makes me think the error is associated to a specific element, but
this does not make sense to show up in a cleanup task.

Instead say "There is not enough space to complete the build.", which
should be more clear that even after cleaning up there is not enough
space.

element.py: Cleanup temporary staging directories on termination

Use utils._tempdir() which in turn uses _signals.terminator() for
this purpose.

This also changes utils._tempdir() to use utils._force_rmtree()
so that it is safe to use for cleaning up the staging directory.

This patch fixes orphaned temporary directories being left behind
in the artifact cache directory at forceful termination time.
