This includes a new command mimicking pytest-runner so that we
can drop this dependency

This was the only setup_requires dependency that we had and
will make like easier for people behind proxies

Remove the 'MAKEFLAGS' and 'V' defaults.

Now that there is a specialised 'make' element, these make-specific
defaults don't make sense here. This element is meant to be a blank
slate for folks to build on.

Note that this is a breaking change, that will require some users to
make changes to their .bst files if they are expecting these environment
variable to be set.

_versions.py: BST_FORMAT_VERSION bumped to 18.

This fixes issue #718

BREAK: manual.yaml: don't set any default env vars

Closes #718

This is to update the workspace CLI to as agreed on the mailing list
https://mail.gnome.org/archives/buildstream-list/2018-September/msg00046.html

This patch also introduces the default workspace directory.

tests/frontend/workspace.py: Refactor of support functions.

Refactoring the support functions for the workspace cli tests.

The main motivation for this was to allow multiple elements to be
created before running the workspace command.

Also the support functions are now broken up so that test that test for
failure can still reuse all the function that create elements, but call
bst workspace with custom arguments and expect other things than success.
