To be able to test vminitd/vmexec/linux specific packages on ci it'd be
a heck of a lot easier if `make` just worked. This should be the last
bit needed. The default goal currently compiles just fine after the
linux specific `make deps` is ran. Next in line would be adding decent
unit tests/actually getting ci setup for the linux bits.
I've added an optional progress handler for rootfs unpacking so that
consumers can show progress. The Ubuntu image takes about 8 seconds to
unpack on my machine, and I'm developing an app where it would be useful
to show progress in the UI.
Total size is determined in an optional first pass that scans archive
headers. Bytes written are then reported during unpacking. The optional
first pass adds 15 (Alpine) to 115 (Ubuntu) ms to unpacking duration on
my machine, depending on image size.
- Closesapple/container#988.
- macOS libarchive is not built with zstd support, so the workaround in
ArchiveReader is to attempt to decompress every archive as zstd. If
decompression fails, we pass the original archive to libarchive. If it
succeeds, we pass the uncompressed archive.
- Adds blob media type recognition for zstd to EXT4Unpacker. Tested zstd
blob unpack using `image pull tonistiigi/hello-world:zstd-docker`.

This refactors the rootfs command to produce an image and have the
ability to create an ext4 formatted block of the init filesystem
directly from the command.

Creates a new Unpacker protocol that defines a single method
```
func unpack(_ image: Image, for platform: Platform, at path: URL, progress: ProgressHandler?) async throws -> Mount
```
This change also removes the `unpack(...)` method from the Image type.
Before
```
let mount = try await image.unpack(for: platform, at: path)
```
After
```
let unpacker = EXT4Unpacker(blockSizeInBytes: 2.gib())
let mount = try await unpacker.unpack(image, for: platform, at: path)
```
