Adrian Reber d5f1caaf50 Add function to get a filtered tarstream diff ...

The newly added function GetDiffTarStream() mirrors the GetDiff()
function. It tries to get the correct layer ID from getLayerID()
and it filters out containerMounts from the tarstream. Thus the
behavior is the same as GetDiff(), but it returns a tarstream.

This also adds the function ApplyDiffTarStream() to apply the tarstream
generated by GetDiffTarStream().

These functions are targeted to support container migration with
root file-system changes.
