5974af661e Python: Update test file 
Makes the `a.b.c.d` test more sensible.

Also adds a test that shows a case where we're currently _not_ getting
the right flow.

3fafb47b16 Python: Fix global flow 
A slightly odd fix, but still morally okay, I think. The main issue
here was that global variables have their first occurrence in an inner
scope inside a so-called "scope entry definition", that then
subsequently flows to the first use of this variable. This meant that
that first use was _not_ a `LocalSourceNode` (since _something_ flowed
into it), and this blocked `trackUseNode` from type-tracking to it (as
it expects all nodes to be `LocalSourceNode`s).

The answer, then, is to say that a `LocalSourceNode` is simply one
that doesn't have flow to it from _any `CfgNode`_ (through one or more
steps). This disregards the flow from the scope entry definition, as
that is flow from an `EssaNode`.

Additionally, it makes sense to exclude `ModuleVariableNode`s. These
should never be considered local sources, since they always have flow
from (at least) the place where the corresponding global variable is
introduced.

e4c3544a3f Python: Add support for from foo.bar import baz 
This turned out to be fairly simple. Given an import such as
```python
from foo.bar.baz import quux
```
we create an API-graph node for each valid dotted prefix of
`foo.bar.baz`, i.e. `foo`, `foo.bar`, and `foo.bar.baz`. For these, we
then insert nodes in the API graph, such that `foo` steps to `foo.bar`
along an edge labeled `bar`, etc.

Finally, we only allow undotted names to hang off of the API-graph
root. Thus, `foo` will have a `moduleImport` edge off of the root, and
a `getMember` edge for `bar` (which in turn has a `getMember` edge for
`baz`).

Relative imports are explicitly ignored.

Finally, this commit also adds inline tests for a variety of ways of
importing modules, including a copy of the "import-helper" tests (with
a few modifications to allow a single annotation per line, as these
get rather long quickly!).
