test/cli: Use empty array as empty output of images/json
Tests mocking the output of GET images/json with fakeClient used an
array with one empty element as an empty response.
Change it to just an empty array.

Sebastiaan van Stijn 0573ec2b01 format (GoDoc) comments with Go 1.19 to prepare for go updates
Older versions of Go do not format these comments, so we can already
reformat them ahead of time to prevent gofmt linting failing once
we update to Go 1.19 or up.

Result of:

    gofmt -s -w $(find . -type f -name '*.go' | grep -v "/vendor/")

With some manual adjusting.

cli/rm_test: Fix TestRemoveForce race condition
Synchronize append on the `removed` slice with mutex because
containerRemoveFunc is called in parallel for each removed container by
`container rm` cli command.
Also reduced the shared access area by separating the scopes of test
cases.

info: skip client-side warning about seccomp profile on API >= 1.42
This warning will be moved to the daemon-side, similar to how it returns
other warnings. There's work in progress to change the name of the default
profile, so we may need to backport this change to prevent existing clients
from printing an incorrect warning if they're connecting to a newer daemon.

change TestNewAPIClientFromFlagsWithHttpProxyEnv to an e2e test
Golang uses a `sync.Once` when determining the proxy to use. This means
that it's not possible to test the proxy configuration in unit tests,
because the proxy configuration will be "fixated" the first time Golang
detects the proxy configuration.

This patch changes TestNewAPIClientFromFlagsWithHttpProxyEnv to an e2e
test so that we can verify the CLI picks up the proxy configuration.

Use designated test domains (RFC2606) in tests
Some tests were using domain names that were intended to be "fake", but are
actually registered domain names (such as mycorp.com).

Even though we were not actually making connections to these domains, it's
better to use domains that are designated for testing/examples in RFC2606:
https://tools.ietf.org/html/rfc2606

context: deprecate support for encrypted TLS private keys

ForwardAllSignals: check if channel is closed, and remove warning
Commit fff164c22e modified ForwardAllSignals to
take `SIGURG` signals into account, which can be generated by the Go runtime
on Go 1.14 and up as an interrupt to support pre-emptable system calls on Linux.

With the updated code, the signal (`s`) would sometimes be `nil`, causing spurious
(but otherwise harmless) warnings to be printed;

    Unsupported signal: <nil>. Discarding.

To debug this issue, I patched v20.10.4 to handle `nil`, and added a debug line
to print the signal in all cases;

```patch
diff --git a/cli/command/container/signals.go b/cli/command/container/signals.go

This patch checks if the channel is closed, and removes the warning (to prevent warnings if new
signals are added that are not in our known list of signals)

We should also consider updating `notfiyAllSignals()`, which currently forwards
_all_ signals (`signal.Notify(sigc)` without passing a list of signals), and
instead pass it "all signals _minus_ the signals we don't want forwarded":

[20.10] Revert "Ignore SIGURG on Linux."
This reverts commit 3c87f01b18.

This commit introduced two regressions;

- spurious "Unsupported signal: <nil>. Discarding."
- docker start --attach hanging if the container does not
  have a TTY attached

Reverting for now, while we dug deeper into what's causing
the regression.
