> Do some refactoring intended to make the code of gc_run() easier for
> understanding:
>  - Remove gc_state::checkpoint_vclock. It was used to avoid rerunning
>    engine gc callback in case no checkpoint was deleted. Since we
>    maintain a list of all available checkpoints, we don't need it for
>    this anymore - we can run gc only if a checkpoint was actually
>    removed from the list.
>  - Rename gc_state::wal_vclock back to gc_state::vclock.
>  - Use bool variables with descriptive names instead of comparing
>    vclock signatures.
>  - Add some comments.

OK to push.
