feat(mount): don't give up on error

/test: fix bad ElemCount/10 lenght (should not be divided)

Fix test log message about number of values put

test suite: Add ElemCount to control how many elements are added.

fix: avoid filtering by prefix unless necessary

feat: add upper-case keys at a known prefix

I need this for testing flatfs.

There's no need to filter by the / prefix.

Instead of giving up when a single datastore fails, operate on all datastores
first. That way:

* If one datastore doesn't support disk usage, we can at least return our best
  estimate for the ones that do.
* If one datastore fails to sync, we won't fail to sync the others.
* If one datastore refuses to close, we'll close the others.

Etc.

Also:

* Drop xerrors. We already need go 1.13 elsewhere.
* Use uber's multierr. It's much simpler than hashicorps (and is already a
  dependency through zap, fx, etc.).

test(suite): add a bunch of prefix tests for the new behavior

Only count a key as an ancestor if there is a separator

This should have already been committed...
