This fix tries to fix logrus formatting by removing `f` from
`logrus.[Error|Warn|Debug|Fatal|Panic|Info]f` when formatting string
is not present.
This fix fixes#23459.

There might be other (valid) reasons for setxattr(2) to fail, so only
ignore it when it's a not supported error (ENOTSUP). Otherwise, bail.

Since certain filesystems don't support extended attributes, ignore

If the destination does not exist, it needs to be created with ownership
mapping to the remapped uid/gid ranges if user namespaces are enabled.
This fixes ADD operations, similar to the prior fixes for COPY and WORKDIR.

Before this PR we used to scan the entire build context when there were
exclusions in the .dockerignore file (paths that started with !). Now we
only traverse into subdirs when one of the exclusions starts with that dir
path.

During "COPY" or other tar unpack operations, a target/destination
parent dir might not exist and should be created with ownership of the
root in the right context (including remapped root when user namespaces
are enabled)

When execute `docker export -o path xxx` and path is a directory docker
has no privilege to write to, daemon will print lots of error logs that
most of them are duplicated and redundant.
This will remove unnecessary error logs and print only once.

Save was failing file integrity checksums due to bugs in both
Windows and Docker. This commit includes fixes to file time handling
in tarexport and system.chtimes that are necessary along with
the Windows platform fixes to correctly support save. With this
change, sysfile_backups for windowsfilter driver are no longer
needed, so that code is removed.

aufs kernel module creates whiteout files on upper layer delete (and
other situations) and those files already are 'translated' regarding
ownership in host terms (e.g. they are already "0:0" owned), so when
these layers are copied around with pkg/archive we don't want to try and
translate these files regarding ownership.

Fixes#17766
Previously, opaque directory whiteouts on non-native
graphdrivers depended on the file order, meaning
files added with the same layer before the whiteout
file `.wh..wh..opq` were also removed.
If that file happened to have subdirs, then calling
chtimes on those dirs after unpack would fail the pull.

The race is between pools.Put which calls buf.Reset and exec.Cmd
doing io.Copy from the buffer; it caused a runtime crash, as
described in #16924:
``` docker-daemon cat the-tarball.xz | xz -d -c -q | docker-untar /path/to/... (aufs ) ```
When docker-untar side fails (like try to set xattr on aufs, or a broken
tar), invokeUnpack will be responsible to exhaust all input, otherwise
`xz` will be write pending for ever.
this change add a receive only channel to cmdStream, and will close it
to notify it's now safe to close the input stream;
in CmdStream the change to use Stdin / Stdout / Stderr keeps the
code simple, os/exec.Cmd will spawn goroutines and call io.Copy automatically.
the CmdStream is actually called in the same file only, change it
lowercase to mark as private.

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.

This fixes the case where directory is removed in
aufs and then the same layer is imported to a
different graphdriver.
Currently when you do `rm -rf /foo && mkdir /foo`
in a layer in aufs the files under `foo` would
only be be hidden on aufs.
The problems with this fix:
1) When a new diff is recreated from non-aufs driver
the `opq` files would not be there. This should not
mean layer differences for the user but still
different content in the tar (one would have one
`opq` file, the others would have `.wh.*` for every
file inside that folder). This difference also only
happens if the tar-split file isn’t stored for the
layer.
2) New files that have the filenames before `.wh..wh..opq`
when they are sorted do not get picked up by non-aufs
graphdrivers. Fixing this would require a bigger
refactoring that is planned in the future.
