artiq_run: refactor, support use from within experiments

You can always (under posix) use #!/usr/bin/env artiq_run as
shebang for experiments and make them executable.
Now, you can also do this (portable):

if __name__ == "__main__":
    from artiq.frontend.artiq_run import run
    run()

to make an experiment executable. The CLI options are all inherited.
Also:

* removed --elf: can be inferred from filename
* did some refactoring and cleanup
* use logging for all messages, except the result printing (use -v to get
parameter changes and dummy scheduler actions)
