config: update evolution-related config

Update the evolution helpers function to support both old-style configuration and
new-style configuration:

    experimental.evolution=all is renamed into experimental.evolution=true

    experimental.evolution=createmarkers is renamed into
    experimental.evolution.createmarkers=true

    experimental.evolution=allowunstable is renamed into
    experimental.evolution.allowunstable=true

    experimental.evolution=exchange is renamed into
    experimental.evolution.exchange=true

We choose to not rename individual config options; keeping the same names
would easy the transition for users but it's something that could be easily
done in the future.
