and only for a trivial check
- use t.TempDir()
- rename vars that collided with package types
- don't use un-keyed structs
- explicitly ignore some errors to please linters
- use iotest.ErrReader

This utility wasn't very related to all other utilities in pkg/ioutils.
Moving it to longpath to also make it more clear what it does.
It looks like there's only a single (public) external consumer of this
utility, and only used in a test, and it's not 100% clear if it was
intentional to use our package, of if it was a case of "I actually meant
`io/ioutil.MkdirTemp`" so we could consider skipping the alias.
While moving the package, I also renamed `TempDir` to `MkdirTemp`, which
is the signature it matches in "os" from stdlib.

Previously, ioutils imported the crypty/sha256 package, because it was
used by the HashData() utility. As a side-effect of that import, the
sha256 algorithm was registered through its `init()` function.
Now that the HashData() utility is removed, the import is no longer needed
in this package, but some parts of our code depended on the side-effect, and
without this, it fail to recognise the algorithms, unless something else
happens to import crypto/sha256 / crypto/sha512, which made our
tests fail:
```
=== Failed
=== FAIL: reference TestLoad (0.00s)
store_test.go:53: failed to parse reference: unsupported digest algorithm
=== FAIL: reference TestSave (0.00s)
store_test.go:82: failed to parse reference: unsupported digest algorithm
=== FAIL: reference TestAddDeleteGet (0.00s)
store_test.go:174: could not parse reference: unsupported digest algorithm
=== FAIL: reference TestInvalidTags (0.00s)
store_test.go:355: assertion failed: error is not nil: unsupported digest algorithm
```
While it would be better to do the import in the actual locations where it's
expected, there may be code-paths we overlook, so instead adding the import
here temporarily. Until the PR in go-digest has been merged and released.

Since Go 1.7, context is a standard package. Since Go 1.9, everything
that is provided by "x/net/context" is a couple of type aliases to
types in "context".
Many vendored packages still use x/net/context, so vendor entry remains
for now.

The Golang built-in gzip library is serialized, and fairly slow
at decompressing. It also only decompresses on demand, versus
pipelining decompression.
This change switches to using the pigz external command
for gzip decompression, as opposed to using the built-in
golang one. This code is not vendored, but will be used
if it autodetected as part of the OS.
This also switches to using context, versus a manually
managed channel to manage cancellations, and synchronization.
There is a little bit of weirdness around manually having
to cancel in the error cases.

partially broken, because a `runDockerCp()` was inadvertently
removed in f26a31e80c
`TestDaemonRestartSaveContainerExitCode()` didn't verify
the actual _Error_ message, so added that to the test,
and updated the test to take into account that the
"experimental" CI enables `--init` on containers.
`TestVolumeCLICreateOptionConflict()` only checked
for an error to occur, but didn't validate if the
error was due to conflicting options.

Fixes case where shutdown occurs before content is synced to disked
on layer creation. This case can leave the layer store in an bad
state and require manual recovery. This change ensures all files
are synced to disk before a layer is committed. Any shutdown that
occurs will only cause the layer to not show up but will allow it to
be repulled or recreated without error.
Added generic io logic to ioutils package to abstract it out of
the layer store package.

Uses lazily-loaded set of sync.Pools for storing buffers that are no
