It was suggested to me that documentation for "docker pull" and "docker
push" should reference "docker login", to make clearer how to specify
credentials for a push or pull operation. Add a note to the manual pages
and reference documentation explaining how registry credentials are
managed.

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.

The form "Save an images" is not correct.
Either "Save an image" or "Save images" work, but since
the save commands accepts multiple images, I chose the
latter.
Fixed in all places where I could grep "Save an image(s)".

Once thin pool gets full, bad things can happen. Especially in case of xfs
it is possible that xfs keeps on retrying IO infinitely (for certain kind
of IO) and container hangs.
One way to mitigate the problem is that once thin pool is about to get full,
start failing some of the docker operations like pulling new images or
creation of new containers. That way user will get warning ahead of time
and can try to rectify it by creating more free space in thin pool. This
can be done either by deleting existing images/containers or by adding more
free space to thin pool.
This patch adds a new option dm.min_free_space to devicemapper graph
driver. Say one specifies dm.min_free_space=10%. This means atleast
10% of data and metadata blocks should be free in pool before new device
creation is allowed, otherwise operation will fail.
By default min_free_space is 10%. User can change it by specifying
dm.min_free_space=X% on command line. A value of 0% will disable the
check.

Following #19995 and #17409 this PR enables skipping userns re-mapping
when creating a container (or when executing a command). Thus, enabling
privileged containers running side by side with userns remapped
containers.
The feature is enabled by specifying ```--userns:host```, which will not
remapped the user if userns are applied. If this flag is not specified,
the existing behavior (which blocks specific privileged operation)
remains.

We cannot rely on the tar command for this type of operation because tar
versions, flags, and functionality can very from distro to distro.
Since this is in the container execution path it is not safe to have
this as a dependency from dockers POV where the user cannot change the
fact that docker is adding these pre and post mount commands.

This makes it so when calling `docker run --rm`, or `docker rm -v`, only
volumes specified without a name, e.g. `docker run -v /foo` instead of
`docker run -v awesome:/foo` are removed.
Note that all volumes are named, some are named by the user, some get a
generated name. This is specifically about how the volume was specified
on `run`, assuming that if the user specified it with a name they expect
it to persist after the container is cleaned up.

Right now, the quiet (-q, --quiet) flag ignores the output
generated from within the container.
However, it ought to be quiet in a way that all kind
of diagnostic output should be ignored, unless the build
process fails.
This patch makes the quiet flag behave in the following way:
1. If the build process succeeds, stdout contains the image ID
and stderr is empty.
2. If the build process fails, stdout is empty and stderr
has the error message and the diagnostic output of that process.
If the quiet flag is not set, then everything goes to stdout
and error messages, if there are any, go to stderr.

Some users expect that the `docker top $CONT` command displays information from the inside container perspective.
They expect that the `docker top $CONT` command displays same information as the `docker exec $CONT ps -ef` command. But it does not.
That's why the `docker top` man page shall explicitly state that the `docker top $CONT` displays information from the host's point of view.
