To make the logic a bit more clear, when snapshotting files, the
parent dirs are now snapshotted in a different loop from the files we
are actually trying to snapshot. Unfortunately this loop is nearly
duplicated but I did managed to group some fo the related logic
together:
- A function to check if the file should be snapshotted (e.g. isn't
whitelisted, etc.)
- Created a `Tar` type to handle some of the logic around tar-ing, e.g.
tracking hardlinks and stat-ing files before adding them
One side effect of this is that now when snapshoting the file system,
files will be stat-ed twice.
* Vendor changes for go-containerregistry switch.
* Manual changes for go-containerregistry switch.
The biggest change is refactoring the tarball unpacking.
* Pull more of container-diff out.
* More vendor removals.
* More unit tests.
