While debugging #32838, it was found (https://github.com/moby/moby/issues/32838#issuecomment-356005845) that the utility VM in some circumstances was crashing. Unfortunately, this was silently thrown away, and as far as the build step (also applies to docker run) was concerned, the exit code was zero and the error was thrown away. Windows containers operate differently to containers on Linux, and there can be legitimate system errors during container shutdown after the init process exits. This PR handles this and passes the error all the way back to the client, and correctly causes a build step running a container which hits a system error to fail, rather than blindly trying to keep going, assuming all is good, and get a subsequent failure on a commit.
With this change, assuming an error occurs, here's an example of a failure which previous was reported as a commit error:

When a container is created if "--network" is set to "host" all the
ports in the container are bound to the host.
Thus, adding "-p" or "--publish" to the command-line is meaningless.
Unlike "docker run" and "docker create", "docker service create" sends
an error message when network mode is host and port bindings are given
This patch however suggests to send a warning message to the client when
such a case occurs.
The warning message is added to "warnings" which are returned from
"verifyPlatformContainerSettings".

On unix, merge secrets/configs handling. This is important because
configs can contain secrets (via templating) and potentially a config
could just simply have secret information "by accident" from the user.
This just make sure that configs are as secure as secrets and de-dups a
lot of code.
Generally this makes everything simpler and configs more secure.

When tailing a container log, if the log file is empty it will cause the
log stream to abort with an unexpected `EOF`.
Note that this only applies to the "current" log file as rotated files
cannot be empty.
This fix just skips adding the "current" file the log tail if it is
empty.

Since commit e9b9e4ace294230c6b8eb has landed, there is a chance that
container.RWLayer is nil (due to some half-removed container). Let's
check the pointer before use to avoid any potential nil pointer
dereferences, resulting in a daemon crash.
Note that even without the abovementioned commit, it's better to perform
an extra check (even it's totally redundant) rather than to have a
possibility of a daemon crash. In other words, better be safe than
sorry.
[v2: add a test case for daemon.getInspectData]
[v3: add a check for container.Dead and a special error for the case]

The imageRefs map was being popualted with containerID, and accessed
with an imageID which would never match.
Remove this broken code because: 1) it hasn't ever worked so isn't
necessary, and 2) because at best it would be racy
ImageDelete() should already handle preventing of removal of used
images.
