Nobody calls At without immediately calling Open.

First step, a mechanical transformation. Cleanups will follow.

Let's save log.Error for things the user can take action on.
Moved all our diagnostics to log.Debug. We can ideally reduce them
even further.

This may have been failing before.

- if equinox says there is a new update, but the version number IS NOT
larger, we interpret that as no update (you may have gotten a newer
version by building it yourself).

- Also export ErrNoUpdateAvailable so clients don't also need to
import the equinox library to check the error.

cc @cryptix comments?

- distinguish log.Error and log.Errorf functions
- Initialize structs with field names
- A bit of unreachable code (defers)
