Petr Viktorin 78fb97105f Make code.FormattedExcinfo.get_source more defensive
When line_index was a large negative number, get_source failed
on `source.lines[line_index]`.
Use the same dummy Source as with a large positive line_index.

Ran Benita a99ca879e7 Mark some public and to-be-public classes as `@final`
This indicates at least for people using type checkers that these
classes are not designed for inheritance and we make no stability
guarantees regarding inheritance of them.

Currently this doesn't show up in the docs. Sphinx does actually support
`@final`, however it only works when imported directly from `typing`,
while we import from `_pytest.compat`.

In the future there might also be a `@sealed` decorator which would
cover some more cases.

Ran Benita 9ab14c6d9c typing: set warn_unreachable
This makes mypy raise an error whenever it detects code which is
statically unreachable, e.g.

    x: int
    if isinstance(x, str):
        ... # Statement is unreachable  [unreachable]

This is really neat and finds quite a few logic and typing bugs.

Sometimes the code is intentionally unreachable in terms of types, e.g.
raising TypeError when a function is given an argument with a wrong
type. In these cases a `type: ignore[unreachable]` is needed, but I
think it's a nice code hint.

Ran Benita be656dd4e4 typing: set disallow_any_generics

Previously this would be turned via `py.path.local("")` into the current

This appears to be what `fspath = fn and py.path.local(fn) or None`
tries to avoid in `getfslineno`'s `TypeError` handling already, if

Ran Benita 0c247be769 Add a few missing type annotations in _pytest._code
These are more "dirty" than the previous batch (that's why they were
left out). The trouble is that `compile` can return either a code object
or an AST depending on a flag, so we need to add an overload to make the
common case Union free. But it's still worthwhile.

Ran Benita 9f3bfe82cf Fix TypeError when importing pytest on Python 3.5.0 and 3.5.1
The typing module on these versions have these issues:

- `typing.Pattern` cannot appear in a Union since it is not considered a
  class.

- `@overload` is not supported in runtime. (On the other hand, mypy
  doesn't support putting it under `if False`, so we need some runtime
  hack).

Add rudimentary mypy type checking

Ran Benita c1167ac552 Add rudimentary mypy type checking
Add a very lax mypy configuration, add it to tox -e linting, and
fix/ignore the few errors that come up. The idea is to get it running
before diving in too much.

This enables:

- Progressively adding type annotations and enabling more strict
  options, which will improve the codebase (IMO).

- Annotating the public API in-line, and eventually exposing it to
  library users who use type checkers (with a py.typed file).

Though, none of this is done yet.
