Updates the rmi code to treat canonical references as related to tagged references from the same repository during deletion.
Canonical references with a different repository name will be treated as separate references.
Updates the remove by ID logic to still remove an image if there is a single tag reference and only canonical references to the same repository remaining.

During a docker exec, if no TTY is specified, the code would still leave stdin open instead of closing it. This change adds handling for the execConfig TTY bool that mirrors what is already done for container config. (Updated this change to be Windows only.)

we store the active sandbox after daemon.containerd.Restore, but there
is a chance the `Restore` will set the container to exit see
(https://github.com/docker/docker/blob/master/libcontainerd/client_linux.go#L469).
so we should check if the container is really running before add it to
activesandbox.

This patch introduces a new experimental engine-level plugin management
with a new API and command line. Plugins can be distributed via a Docker
registry, and their lifecycle is managed by the engine.
This makes plugins a first-class construct.
For more background, have a look at issue #20363.
Documentation is in a separate commit. If you want to understand how the
new plugin system works, you can start by reading the documentation.
Note: backwards compatibility with existing plugins is maintained,
albeit they won't benefit from the advantages of the new system.

Symlinks are currently not getting cleaned up when removing layers since only the root directory is removed.
On remove, read the link file and remove the associated link from the link directory.

This change updates how we handle long lines of output from the
container. The previous logic used a bufio reader to read entire lines
of output from the container through an intermediate BytesPipe, and that
allowed the container to cause dockerd to consume an unconstrained
amount of memory as it attempted to collect a whole line of output, by
outputting data without newlines.
To avoid that, we replace the bufio reader with our own buffering scheme
that handles log lines up to 16k in length, breaking up anything longer
than that into multiple chunks. If we can dispense with noting this
detail properly at the end of output, we can switch from using
ReadBytes() to using ReadLine() instead. We add a field ("Partial") to
the log message structure to flag when we pass data to the log driver
that did not end with a newline.
The Line member of Message structures that we pass to log drivers is now
a slice into data which can be overwritten between calls to the log
driver's Log() method, so drivers which batch up Messages before
processing them need to take additional care: we add a function
(logger.CopyMessage()) that can be used to create a deep copy of a
Message structure, and modify the awslogs driver to use it.
We update the jsonfile log driver to append a "\n" to the data that it
logs to disk only when the Partial flag is false (it previously did so
unconditionally), to make its "logs" output correctly reproduce the data
as we received it.
Likewise, we modify the journald log driver to add a data field with
value CONTAINER_PARTIAL_MESSAGE=true to entries when the Partial flag is
true, and update its "logs" reader to refrain from appending a "\n" to
the data that it retrieves if it does not see this field/value pair (it
also previously did this unconditionally).
