0032bae041 Make pgen2's grammar ambiguity detection handle more cases 
Under the old implementation,

```
outer: A [inner] B C
inner: B C [inner]
```

wouldn't get detected as the ambiguous grammar that it is, whereas

```
outer: A rest
rest: [inner] B C
inner: B C [inner]
```

would.

This would manifest itself as non-determinism in the DFA state
generation. See the discussion #62 on for a full explanation.

This modifies the ambiguity detection to work on a broader class of
issues, so it should now hopefully detect all cases where the given
grammar is ambiguous.

At some point, we could extend this logic to allow developers to
optionally set precedence of grammar productions, which could resolve
ambiguities, but that's not a strict requirement for parsing python.

ad57a51800 Fix line continuation characters inside f-strings 
Line continuation characters are valid inside of strings, but weren't
handled correctly in certain cases with f-strings, due to some small
tokenizer bugs.

This pull request to address those issues, and adds tests to validate
the new logic.

SyntaxError: unexpected EOF while parsing

instead of

SyntaxError: invalid syntax
