Pass upstream client's user agent through to registry on operations beyond pulls

This allows a user to specify explicitly to enable
automatic copying of data from the container path to the volume path.
This does not change the default behavior of automatically copying, but
does allow a user to disable it at runtime.

This adds support for the passthrough on build, push, login, and search.
Revamp the integration test to cover these cases and make it more
robust.
Use backticks instead of quoted strings for backslash-heavy string
contstands.

This cleans up some of the use of the filepoller which makes reading
significantly more robust and gives fewer changes to fallback to the
polling based watcher.
In a lot of cases, if the file was being rotated while we were adding it
to the watcher, it would return an error that the file doesn't exist and
would fallback.
In some cases this fallback could be triggered multiple times even if we
were already on the fallback/poll-based watcher.
It also fixes an open file leak caused by not closing files properly on
rotate, as well as not closing files that were read via the `tail`
function until after the log reader is completed.
Prior to the above changes, it was relatively simple to cause the log
reader to error out by having quick rotations, for example:
```
$ docker run --name test --log-opt max-size=10b --log-opt max-files=10
-d busybox sh -c 'while true; do usleep 500000; echo hello; done'
$ docker logs -f test
```
After these changes I can run this forever without error.
Another fix removes 2 `os.Stat` calls when rotating files. The stat
calls are not needed since we are just calling `os.Rename` anyway, which
will in turn also just produce the same error that `Stat` would.
These `Stat` calls were also quite expensive.
Removing these stat calls also seemed to resolve an issue causing slow
memory growth on the daemon.

so that the user knows what's not in the container but should be.
Its not always easy for the user to know what exact command is being run
when the 'docker run' is embedded deep in something else, like a Makefile.
Saw this while dealing with the containerd migration.

Changes how the Engine interacts with Registry servers on image pull.
Previously, Engine sent a User-Agent string to the Registry server
that included only the Engine's version information. This commit
appends to that string the fields from the User-Agent sent by the
client (e.g., Compose) of the Engine. This allows Registry server
operators to understand what tools are actually generating pulls on
their registries.

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.

Component: engine
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.

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.

The GCP logging driver is calling out to GCP cloud service on package
init.
This is regardless if you are using GCP logging or not.
This change makes this happen on the first invocation of a new GCP
logging driver instance instead.
