1. Support for preseeded fastmaps.
A preseeded fastmap is a fastmap created by tools such as ubinize.
That way fastmap deployment is less painful and fast attach is
available upon first boot.

2. Refine various checks.
Detect misconfigured setups better.

3. Allow a forcing a full scan.
Forcing a full scan is useful mostly for debugging and making sure that
it works.

4. Remove the experimental stigma.
