Discovered a few instances, where loop variable is incorrectly used
within a test closure, which is marked as parallel.
Few of these were actually loops over singleton slices, therefore the issue
might not have surfaced there (yet), but it is good to fix there as
well, as this is an incorrect pattern used across different tests.

Rootlesskit doesn't currently handle IPv6 addresses, causing TestNetworkLoopbackNat
and TestNetworkNat to fail;
Error starting userland proxy:
error while calling PortManager.AddPort(): listen tcp: address :::8080: too many colons in address
This patch:
- Updates `getExternalAddress()` to pick IPv4 address if both IPv6 and IPv4 are found
- Update TestNetworkNat to net.JoinHostPort(), so that square brackets are used for
IPv6 addresses (e.g. `[::]:8080`)

Using `d.Kill()` with rootless mode causes the restarted daemon to not
be able to start containerd (it times out).
Originally this was SIGKILLing the daemon because we were hoping to not
have to manipulate on disk state, but since we need to anyway we can
shut it down normally.
I also tested this to ensure the test fails correctly without the fix
that the test was added to check for.

Adds a test case for the case where dockerd gets stuck on startup due to
hanging `daemon.shutdownContainer`

This fixes a regression based on expectations of the runtime:
```
docker pull arm32v7/alpine
docker run arm32v7/alpine
```
Without this change, the `docker run` will fail due to platform
matching on non-arm32v7 systems, even though the image could run
(assuming the system is setup correctly).
This also emits a warning to make sure that the user is aware that a
platform that does not match the default platform of the system is being
run, for the cases like:
```
docker pull --platform armhf busybox
docker run busybox
```
Not typically an issue if the requests are done together like that, but
if the image was already there and someone did `docker run` without an
explicit `--platform`, they may very well be expecting to run a native
version of the image instead of the armhf one.
This warning does add some extra noise in the case of platform specific
images being run, such as `arm32v7/alpine`, but this can be supressed by
explicitly setting the platform.

After dicussing with maintainers, it was decided putting the burden of
providing the full cap list on the client is not a good design.
Instead we decided to follow along with the container API and use cap
add/drop.
This brings in the changes already merged into swarmkit.

If the container specified in `--volumes-from` did not exist, the
API returned a 404 status, which was interpreted by the CLI as the
specified _image_ to be missing (even if that was not the case).
This patch changes these error to return a 400 (bad request);
Before this change:
# make sure the image is present
docker pull busybox
docker create --volumes-from=nosuchcontainer busybox
# Unable to find image 'busybox:latest' locally
# latest: Pulling from library/busybox
# Digest: sha256:95cf004f559831017cdf4628aaf1bb30133677be8702a8c5f2994629f637a209
# Status: Image is up to date for busybox:latest
# Error response from daemon: No such container: nosuchcontainer

# make sure the image is present

When a container is left running after the daemon exits (e.g. the daemon
is SIGKILL'd or crashes), it should stop any running containers when the
daemon starts back up.
What actually happens is the daemon only sends the container's
configured stop signal and does not check if it has exited.
If the container does not actually exit then it is left running.
This fixes this unexpected behavior by calling the same function to shut
down the container that the daemon shutdown process does.

This enables image lookup when creating a container to fail when the
reference exists but it is for the wrong platform. This prevents trying
to run an image for the wrong platform, as can be the case with, for
example binfmt_misc+qemu.

Metrics collectors generally don't need the daemon to prime the stats
with something to compare since they already have something to compare
with.
Before this change, the API does 2 collection cycles (which takes
roughly 2s) in order to provide comparison for CPU usage over 1s. This
was primarily added so that `docker stats --no-stream` had something to
compare against.
Really the CLI should have just made a 2nd call and done the comparison
itself rather than forcing it on all API consumers.
That ship has long sailed, though.
With this change, clients can set an option to just pull a single stat,
which is *at least* a full second faster:
Old:
```
time curl --unix-socket
/go/src/github.com/docker/docker/bundles/test-integration-shell/docker.sock
http://./containers/test/stats?stream=false\&one-shot=false > /dev/null
2>&1
real0m1.864s
user0m0.005s
sys0m0.007s

/go/src/github.com/docker/docker/bundles/test-integration-shell/docker.sock
http://./containers/test/stats?stream=false\&one-shot=false > /dev/null
2>&1
real0m1.173s
user0m0.010s
sys0m0.006s
```
New:
```
time curl --unix-socket
/go/src/github.com/docker/docker/bundles/test-integration-shell/docker.sock
http://./containers/test/stats?stream=false\&one-shot=true > /dev/null
2>&1
real0m0.680s
user0m0.008s
sys0m0.004s
time curl --unix-socket

2>&1
real0m0.156s
user0m0.007s
sys0m0.007s
```
This fixes issues with downstreams ability to use the stats API to
collect metrics.

This makes sure that things like `--tmpfs` mounts over an anonymous
volume don't create volumes uneccessarily.
One method only checks mountpoints, the other checks both mountpoints
and tmpfs... the usage of these should likely be consolidated.
Ideally, processing for `--tmpfs` mounts would get merged in with the
rest of the mount parsing. I opted not to do that for this change so the
fix is minimal and can potentially be backported with fewer changes of
breaking things.
Merging the mount processing for tmpfs can be handled in a followup.

Docker Desktop (on MAC and Windows hosts) allows containers
running inside a Linux VM to connect to the host using
the host.docker.internal DNS name, which is implemented by
VPNkit (DNS proxy on the host)
This PR allows containers to connect to Linux hosts
by appending a special string "host-gateway" to --add-host
e.g. "--add-host=host.docker.internal:host-gateway" which adds
host.docker.internal DNS entry in /etc/hosts and maps it to host-gateway-ip
This PR also add a daemon flag call host-gateway-ip which defaults to
the default bridge IP
Docker Desktop will need to set this field to the Host Proxy IP
so DNS requests for host.docker.internal can be routed to VPNkit

Trying to link to a non-existing container is not valid, and should return an
"invalid parameter" (400) error. Returning a "not found" error in this situation
would make the client report the container's image could not be found.
