Move fetch logic from FetchQueue to Element

The queue shouldn't need to know about individual sources. This is in
line with _track() and _get_consistency().

Expose base class for Git source plugins

Add a `_GitSourceBase` class to act as the base class for deriving
source plugins that work with Git. The first user of this base class is
the `git` source plugin that's in core at the moment.

The contents of this base class is almost identical to the existing `GitSource`
class. The two notable differences are:

- the private methods now have leading underscores, as some were missing
  it originally
- the name of the class

Note that we are exposing a private member here as we expect it to move to a
separate package soon. See the following discussion for more details:
https://gitlab.com/BuildStream/buildstream/issues/739#note_124819869

Fixes #739.

_project::_find_project_dir: fix error message

Now that we are also looking for WORKSPACE_PROJECT_FILE, we should add
it to the error message. While we're there, also mention the directory
we are looking in - this could help scripters be clear about what went
wrong.

The new error message looks like this:

    Error loading project: None of ['project.conf', '.bstproject.yaml']
    found in '/src/temp/blah' or any of its parent directories

BREAK: remove auto-init behaviour

In the event that the project could not be found, stop BuildStream from
asking if the user would like to create a new project. Exit with error
instead, and give a hint to the user in case they're new.

As proposed on the mailing list here:
https://mail.gnome.org/archives/buildstream-list/2018-December/msg00082.html

The new interaction looks like this:

    $ bst show nonsuch.bst
    No project found. You can create a new project like so:

        bst init

    Error loading project: None of ['project.conf', '.bstproject.yaml']
    found in '/src/temp/blah' or any of its parent directories

Fixes #826

tests/frontend/logging.py: Fix regex Deprecation Warning

Use raw strings for regex searches, which is the preferred way to do
regular expressions in Python.

Without this patch, currently we get the following warnings:

```
tests/frontend/logging.py:44
  /builds/BuildStream/buildstream/dist/buildstream/tests/frontend/logging.py:44: DeprecationWarning: invalid escape sequence \[
    m = re.search("\[\d\d:\d\d:\d\d\]\[\]\[\] SUCCESS Checking sources", result.stderr)

tests/frontend/logging.py:80
  /builds/BuildStream/buildstream/dist/buildstream/tests/frontend/logging.py:80: DeprecationWarning: invalid escape sequence \d
    m = re.search("\d\d:\d\d:\d\d,\d\d:\d\d:\d\d.\d{6},\d\d:\d\d:\d\d,,,SUCCESS,Checking sources", result.stderr)
```

buildstream/utils.py: Fix regex Deprecation Warning

Specify flags at the start of the _expression_ as per the recommendation
of the standard library.

Without this patch, we currently get the following warning:

  /builds/BuildStream/buildstream/dist/buildstream/buildstream/utils.py:213: DeprecationWarning: Flags not at the start of the _expression_ '\\/[^/]*\\Z(?ms)'
    regexer = re.compile(_expression_)
