Pass kwargs to run_sync?

[davidbrochart]

It would be nice if to_process.run_sync, to_thread.run_sync, and from_thread.run_sync could accept kwargs.
Is there a reason for not supporting it, or was it just not implemented until now?

See discussion in #403, python-trio/trio#470

Thanks @uSpike! So do you recommend using a lambda?

run_sync(lambda: my_func('foo', kwarg='bar'))

[uSpike]

Yep that's the best way in my opinion, otherwise functools.partial.

Thanks!
