In `ApplyLayer` and `Untar`, the stream is magically decompressed. Since
this is not able to be toggled, rather than break this ./pkg/ API, add
an `ApplyUncompressedLayer` and `UntarUncompressed` that does not
magically decompress the layer stream.

Adds TarResource and CopyTo functions to be used for creating
archives for use with the new `docker cp` behavior.
Adds multiple test cases for the CopyFrom and CopyTo
functions in the pkg/archive package.

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

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.

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.

If we tear through a few layers of abstraction, we can get at the inodes
contained in a directory without having to stat all the files. This
allows us to eliminate identical files much earlier in the changelist

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

Component: engine
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.
