Add tests on:
- changes.go
- archive.go
- wrap.go
Should fix#11603 as the coverage is now 81.2% on the ``pkg/archive``
package. There is still room for improvement though :).

on overlay fs, the mtime of directories changes in a container where new
files are added in an upper layer (e.g. '/etc'). This flags the

This change modifies the chmod bits of build context archives built on
windows to preserve the execute bit and remove the r/w bits from
grp/others.
Also adjusted integ-cli tests to verify permissions based on the platform
the tests are running.
Fixes#11047.

Currently TestBuildRenamedDockerfile fails since passing
custom dockerfile paths like:
docker build -f dir/file .
fails on windows because those are unix paths. Instead, on
windows accept windows style paths like:
docker build -f dir\file .
and convert them to unix style paths using the helper we
have in `pkg/archive` so that daemon can correctly locate
the path in the context.

Currently pkg/archive stores nested windows files with
backslashes (e.g. `dir\`, `dir\file.txt`) and this causes
tar not being correctly extracted on Linux daemon.
This change assures we canonicalize all paths to unix
paths and add them to tar with that name independent of platform.
Fixes the following test cases for Windows CI:
- TestBuildAddFileWithWhitespace
- TestBuildCopyFileWithWhitespace
- TestBuildAddDirContentToRoot
- TestBuildAddDirContentToExistingDir
- TestBuildCopyDirContentToRoot
- TestBuildCopyDirContentToExistDir
- TestBuildDockerignore
- TestBuildEnvUsage
- TestBuildEnvUsage2

If .dockerignore mentions either then the client will send them to the

to simulate them never being sent in the first place.

To avoid an expensive call to archive.ChangesDirs() which walks two directory
trees and compares every entry, archive.ApplyLayer() has been extended to
also return the size of the layer changes.

With 32ba6ab from #9261, TempArchive now closes the underlying file and
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.
Add a Close method to TempArchive that does a no-op if the underlying
file has already been closed.

This fixes the removal of TempArchives which can read with only one
read. Such archives weren't getting removed because EOF wasn't being
triggered.

pkg/archive contains code both invoked from cli (cross platform) and
daemon (linux only) and Unix-specific dependencies break compilation on
Windows. We extracted those stat-related funcs into platform specific
implementations at pkg/system and added unit tests.

In an effort to make layer content 'stable' between import
and export from two different graph drivers, we must resolve
an issue where AUFS produces metadata files in its layers
which other drivers explicitly ignore when importing.
The issue presents itself like this:
- Generate a layer using AUFS
- On commit of that container, the new stored layer contains
AUFS metadata files/dirs. The stored layer content has some
tarsum value: '1234567'
- `docker save` that image to a USB drive and `docker load`
into another docker engine instance which uses another
graph driver, say 'btrfs'
- On load, this graph driver explicitly ignores any AUFS metadata
that it encounters. The stored layer content now has some
different tarsum value: 'abcdefg'.
The only (apparent) useful aufs metadata to keep are the psuedo link
files located at `/.wh..wh.plink/`. Thes files hold information at the
RW layer about hard linked files between this layer and another layer.
The other graph drivers make sure to copy up these psuedo linked files
but I've tested out a few different situations and it seems that this
is unnecessary (In my test, AUFS already copies up the other hard linked
files to the RW layer).
This changeset adds explicit exclusion of the AUFS metadata files and
directories (NOTE: not the whiteout files!) on commit of a container
using the AUFS storage driver.
Also included is a change to the archive package. It now explicitly
ignores the root directory from being included in the resulting tar archive
for 2 reasons: 1) it's unnecessary. 2) It's another difference between
what other graph drivers produce when exporting a layer to a tar archive.
