On OS X, sometimes the userscript exited before the QSocketNotifier was
triggered. By doing a final read when cleaning up we make sure we don't
miss anything.
Fixes#1533.
Since we're not using those functions as argparse callbacks anymore, we
can write a normal function instead of factories, which simplifies
things a lot.
This means:
- An annotation like (int, str) is now typing.Union[int, str].
- utils.typing got expanded so it acts like the real typing.py, with
issubclass() working properly with typing.Union and __union_params__
being set.
- A literal string doesn't exist anymore as annotation, instead
@cmdutils.argument now has a 'choices' argument which can be used like
@cmdutils.argument('arg', choices=['val1', 'val2']).
- Argument validating/converting is now entirely handled by
argparser.type_conv instead of relying on python's argparse, i.e.
type/choices is now not passed to argparse anymore.
TestArgument didn't clear the globals as the fixture was inside
TestRegister.
This means test_run_vulture failed in funny ways because run_vulture.py
generated a whitelist containing "<locals>" for commands:
tests/unit/scripts/test_run_vulture.py:55: in run
return run_vulture.run([str(e.basename) for e in files])
scripts/dev/run_vulture.py:146: in run
vult.scavenge(files + [whitelist_file.name])

Before we used a {'nargs': '*'} annotation for the respective argument
to tell qutebrowser it's optional for the commandline. Now we instead
use a star_args_optional argument for @cmdutils.register as a first step
towards freeing up argument annotations for PEP 484.
See #637.
If the process emitted error() and then finished(), we already set
self._filepath to None and did other cleanup.
Instead we do the file reading inside _cleanup and call that from
on_process_error and on_process_finished.
When there was an error, the finished signal will be emitted too anyways, so if
we call cleanup here, we'll call it twice which means we'll get an exception.
Supersedes #1175.
