This makes the "Buffering to disk" part of `docker push` 70% faster in
my use-case (having already applied #12833).
fsync'ing here serves no valuable purpose: if the drive's operation is
interrupted, so it the program's, and this archive has no value other
than the immediate and transient one.

This change modifies the chmod bits of build context archives built on

Also adjusted integ-cli tests to verify permissions based on the platform

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

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.

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.
