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.
