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.

Nalin Dahyabhai 97326e1d2f Support for per-container uid/gid mapping: lower
Expose reading and writing ID mapping in the archive and chrootarchive
packages, and in the driver interface.  Generally this means that
when computing or applying diffs, we need to have ID mappings passed in
that are specific to the layers we're using.

Nalin Dahyabhai c21a98e79e changes: check for whiteout when looking at lower layers
When deciding whether to mark a file as added or modified, we check for
the presence of an item with the same path in a layer from which the
current later might have inherited a different version of the file.
This can be tripped up by overlay-style whiteout entries, which have the
same name as the file which they mark as having been removed.  Also make
sure that we don't mistakenly count, as inherited, a file with the same
name that was in a lower layer, but which was removed by an intermediate
layer.

Daniel J Walsh f39066fe1b Update packages to match latest code in moby/pkg
Had to vendor in a new version of golang.org/x/net to build
Also had to make some changes to drivers to handle
archive.Reader -> io.Reader
archive.Archive -> io.ReadCloser

Also update .gitingore to ignore emacs files, containers-storage.*
and generated man pages.

Also no longer test travis against golang 1.7, cri-o, moby have also
done this.

Stefan J. Wernli 041a9510c6 Fixing 'docker save' on Windows.
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.

Phil Estes 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.

Shijiang Wei e2c6a8be7c Add the parent directory to changes set if new files are generated
The "TestChangesWithChanges" case randomlly fails on my development
VM with the following errors:
```
--- FAIL: TestChangesWithChanges (0.00s)
        changes_test.go:201: no change for expected change C /dir1/subfolder != A /dir1/subfolder/newFile
```

If I apply the following patch to changes_test.go, the test passes.

```diff
diff --git a/pkg/archive/changes_test.go b/pkg/archive/changes_test.go
index 290b2dd..ba1aca0 100644
--- a/pkg/archive/changes_test.go
+++ b/pkg/archive/changes_test.go
@@ -156,6 +156,7 @@ func TestChangesWithChanges(t *testing.T) {
        }
        defer os.RemoveAll(layer)
        createSampleDir(t, layer)
+       time.Sleep(5 * time.Millisecond)
        os.MkdirAll(path.Join(layer, "dir1/subfolder"), 0740)

        // Let's modify modtime for dir1 to be sure it's the same for the two layer (to not having false positive)
```

It seems that if a file is created immediately after the directory is created,
the `archive.Changes` function could't recognize that the parent directory of
the new file is modified.

Perhaps the problem may reproduce on machines with low time precision?
I had successfully reproduced the failure on my development VM as well as
a VM on DigitalOcean.
