Protect filesystem subtrees from concurrent manipulation during critical sections if engine actions are called asynchronously. This change provides coordination between the `Snapshotter` and the `FileWriter`. For example, the `FileWriter` should be blocked from perturbing the same directory tree if a Gather-Snapshot is taking place along that tree simultaneously. This will ensure the fingerprint data accumulated during the `Gather` phase will correspond unambiguously to the data included in the snapshot. Extend build flags to kopia snapshotter This package now imports fswalker which can only be built for darwin,amd64 or linux,amd64
