Docker logs was only closing the logger when the HTTP response writer received a close notification, however in non-follow mode the writer never receives a close. This means that the daemon would leak the file handle to the log, preventing the container from being removed on Windows (file in use error). This change explicitly closes the log when the end of stream is hit.

Add a paragraph about how to force a stack trace dump to the daemon log.
This feature was added in Docker 1.9 I believe, but documentation was
never added.

This fix addressed the issue of test TestRestartStoppedContainer
in #21211. Inside the test, a `docker restart` command is
followed by a `docker logs` command. However, `docker restart`
returns immediately so there is no guarantee that `docker logs`
will wait until the restarted container completes the command
`echo foobar`.
This fix use the check of `{{.State.Running}} = false` to make
sure that the restarted container has already finished, before
invoking the `docker logs` command. The timeout is set to 20s
to make sure it passes WindowsTP4 check.
This fixes#21211.

When following a journal-based log, it was possible for the worker
goroutine, which reads the journal using the journal context and sends
entry data down the message channel, to be scheduled after the function
which started it had returned. This could create problems, since the
invoking function was closing the journal context object and message
channel before it returned, which could trigger use-after-free segfaults
and write-to-closed-channel panics in the worker goroutine.
Make the cleanup in the invoking function conditional so that it's only
done when we're not following the logs, and if we are, that it's left to
the worker goroutine to close them.

The journald log reader keeps a map of following readers so that it can
close them properly when the journald reader object itself is closed,
but it was possible for its worker goroutine to be scheduled so that the
worker attempted to remove a reader from the map before the reader had
been added to the map. This patch adds the item to the map before
starting the goroutine which is expected to eventually remove it.

This (the first tagged hcsshim release) fixes long-path bugs on
Windows TP5 that affect commit and save. These bugs were blocking
commit of Windows containers that had node.js installed.

All other options we have use `=` as separator, labels,
log configurations, graph configurations and so on.
We should be consistent and use `=` for the security
options too.
