We should warn users who use the `--dns` command line option to point
DNS to a localhost address, either IPv4 or IPv6. Unless they have
specifically set up the container as a DNS server or are using
--net=host (which is why this should be allowed, but warned on because
those are pretty unique cases) a localhost address as a resolver will
not reach what they might expect (e.g. expecting it will hit localhost
on the Docker daemon/host).
Added a test for the message, and fixed up tests to separate stdout and
stderr that were using `--dns=127.0.0.1` to test the options.

Thanks to @ahmetalpbalkan for noticing... we had an old check in this
testcase that no longer applied (due to stuff being removing recently).
However, while in there I added a check to make sure that the file referenced
by the query parameter isn't used at all.

Manifest is now generated during a v2 push, not relying on previously generated hashes. When pushing a layer, the hash is directly calculated from the tar contents which will be pushed. Computing the hash on push ensures that the hash contents always match what is seen by the registry. This also mitigates issues with tarsum differences and permits using pure SHA digests.
Additionally the new manifest function is moved to the unit tests since it is no longer called outside the tests.

This makes it much simpler to add new "frozen" images -- simply add them to the `Dockerfile` and in `hack/make/.ensure-frozen-images` and you're off to the races.

parser_test only needed the directory-names for
the tests to run. This replaces f.Readdir() with
f.Readdirnames() to only return the names.

When we run `docker login` we will be asked to input our username.
Prior to this PR, "userA" and " userA" will be considered as two
diferrent user, which is not right.

Implemented a FakeStorage alternative that supports spinning
up a remote container on DOCKER_TEST_HOST to serve files over
an offline-compiled Go static web server image so that tests which
use URLs in Dockerfile can build them over at the daemon side.
`fakeStorage` function now automatically chooses if it should
use a local httptest.Server or a remote container.
This fixes the following tests when running against a remote
daemon:
- `TestBuildCacheADD`
- `TestBuildCopyWildcardNoFind`
- `TestBuildCopyWildcardCache`
- `TestBuildADDRemoteFileWithCache`
- `TestBuildADDRemoteFileWithoutCache`
- `TestBuildADDRemoteFileMTime`
- `TestBuildADDLocalAndRemoteFilesWithCache`
- `TestBuildADDLocalAndRemoteFilesWithoutCache`
- `TestBuildFromURLWithF`
- `TestBuildApiDockerFileRemote`

This patch adds detail on how the host's `/etc/resolv.conf` file is
filtered when creating the copy for the container.

Previously on error either from the daemon or from the api it is just
exiting with exit status 1 but not performing a shutdown.
This can produce insconsistent state depending on where the error came
from.
This makes sure that before we exit on error that the engine gets fully
shutdown.
