pkg/archive: remove unnecessary Archive and Reader type
The `archive` package defines aliases for `io.ReadCloser` and
`io.Reader`. These don't seem to provide an benefit other than type
decoration. Per this change, several unnecessary type cases were
removed.

617c352e92 Don't create devices if in a user namespace
If we are running in a user namespace, don't try to mknod as
it won't be allowed.  libcontainer will bind-mount the host's
devices over files in the container anyway, so it's not needed.

The chrootarchive package does a chroot (without mounting /proc) before
its work, so we cannot check /proc/self/uid_map when we need to.  So
compute it in advance and pass it along with the tar options.

a9c6169138 Remove flush(stdout) in pkg/chrootarchive/diff_unix.go and improve error reporting of flush() to fix #21103
pkg/chrootarchive/diff_unix.go erroneously calls flush on stdout, which tries to read from stdout returning an error.
This has been fixed by removing the call and by modifying flush to return errors and checking for these errors on calls to flush.

442b45628e Add user namespace (mapping) support to the Docker engine
Adds support for the daemon to handle user namespace maps as a
per-daemon setting.

Support for handling uid/gid mapping is added to the builder,
archive/unarchive packages and functions, all graphdrivers (except
Windows), and the test suite is updated to handle user namespace daemon
rootgraph changes.

56bf275e32 archive, chrootarchive: split out decompression
In `ApplyLayer` and `Untar`, the stream is magically decompressed. Since
this is not able to be toggled, rather than break this ./pkg/ API, add
an `ApplyUncompressedLayer` and `UntarUncompressed` that does not
magically decompress the layer stream.
