test: use `T.TempDir` to create temporary test directory
This commit replaces `ioutil.TempDir` with `t.TempDir` in tests. The
directory created by `t.TempDir` is automatically removed when the test
and all its subtests complete.

Prior to this commit, temporary directory created using `ioutil.TempDir`
needs to be removed manually by calling `os.RemoveAll`, which is omitted
in some tests. The error handling boilerplate e.g.
	defer func() {
		if err := os.RemoveAll(dir); err != nil {
			t.Fatal(err)
		}
	}
is also tedious, but `t.TempDir` handles this for us nicely.

storage: add option force_mask=
force_mask sets a permission mask used for the new files and
directories.

It is useful for using a NFS share for the rootless storage.  It
requires this change in fuse-overlayfs:

[storage]
  driver = "overlay"
  graphroot = "/mnt/nfs/home/storage"
  [storage.options]

Derek Ch b48f4bf523 fix a race crash when building with "ADD some-broken.tar.xz ..."
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.

Josh Hawn 75f6929b44 Fix `docker cp` Behavior With Symlinks
[pkg/archive] Update archive/copy path handling

  - Remove unused TarOptions.Name field.
  - Add new TarOptions.RebaseNames field.
  - Update some of the logic around path dir/base splitting.
  - Update some of the logic behind archive entry name rebasing.

[api/types] Add LinkTarget field to PathStat

[daemon] Fix stat, archive, extract of symlinks

  These operations *should* resolve symlinks that are in the path but if the
  resource itself is a symlink then it *should not* be resolved. This patch
  puts this logic into a common function `resolvePath` which resolves symlinks
  of the path's dir in scope of the container rootfs but does not resolve the
  final element of the path. Now archive, extract, and stat operations will
  return symlinks if the path is indeed a symlink.

[api/client] Update cp path hanling

[docs/reference/api] Update description of stat

  Add the linkTarget field to the header of the archive endpoint.
  Remove path field.

[integration-cli] Fix/Add cp symlink test cases

  Copying a symlink should do just that: copy the symlink NOT
  copy the target of the symlink. Also, the resulting file from
  the copy should have the name of the symlink NOT the name of
  the target file.

  Copying to a symlink should copy to the symlink target and not
  modify the symlink itself.

cleans it up as soon as the file's contents have been read. When pushing
an image, PushImageLayerRegistry attempts to call Close() on the layer,
which is a TempArchive that has already been closed. In this situation,
Close() returns an "invalid argument" error.

file has already been closed.
