Now from a single invocation of `docker save`, you can specify multiple
images to include in the output tar, or even just multiple tags of a
particular image/repo.
```
> docker save -o bundle.tar busybox ubuntu:lucid ubuntu:saucy fedora:latest
> tar tf ./bundle.tar | wc -l
42
> tar xOf ./bundle.tar repositories
{"busybox":{"latest":"2d8e5b282c81244037eb15b2068e1c46319c1a42b80493acb128da24b2090739"},"fedora":{"latest":"58394af373423902a1b97f209a31e3777932d9321ef10e64feaaa7b4df609cf9"},"ubuntu":{"lucid":"9cc9ea5ea540116b89e41898dd30858107c1175260fb7ff50322b34704092232","saucy":"9f676bd305a43a931a8d98b13e5840ffbebcd908370765373315926024c7c35e"}}
```
Further, this fixes the bug where the `repositories` file is not created
when saving a specific tag of an image (e.g. ubuntu:latest)

--help and help are successful commands so output should not go to error.
QE teams have requested this change, also users doing docker help | less
or docker run --help | less would expect this to work.
Usage statement should only be printed when the user asks for it.
Errors should print error message and then suggest the docker COMMAND --help
command to see usage information.
The current behaviour causes the user to have to search for the error message
and sometimes scrolls right off the screen. For example a error on a
"docker run" command is very difficult to diagnose.
Finally erros should always exit with a non 0 exit code, if the user
makes a CLI error.

`rm -f` was originally deprecated in favor of `rm --stop/--kill` since `rm
-f` was sending SIGTERM and potentially very slow.
Instead this will bring back `rm -f` but use SIGKILL isntead

/tmp is often a tmpfs file system and large temporary files could cause
docker commands to fail. Also using /tmp potentially allows users on the
system to get access to content, or even attack the content. Moving the tmpdir to
/var/lib/container/tmp will protect the data.

We add a --device flag which can be used like:
docker run --device /dev/sda:/dev/xvda:rwm ubuntu /bin/bash
To allow the container to have read write permissions to access the host's /dev/sda via a node named /dev/xvda in the container.
Note: Much of this code was written by Dinesh Subhraveti dineshs@altiscale.com (github: dineshs-altiscale) and so he deserves a ton of credit.

Currently the docker logs timestamp flag generates log entries like:
$ sudo docker logs -ft daemon_dave
[May 10 13:06:17.934] hello world
It uses Go's StampMilli timestamp to generate the timestamp. The entry
is also wrapped in [ ].
This is non-standard operational timestamp and one that will require
custom parsing.
The new timestamp is RFC3999Nano and generates entries like:
2014-05-10T17:42:14.999999999Z07:00 hello world
These are readily parsed by tools like ELK.

The Docker btrfs graph driver does not interact well with SELinux at present.
If btrfs mounts the same file in several locations, the same SELinux label will
be applied to all mountpoints. In the context of the graph driver, things such
as shared libraries become inaccessible to containers due to SELInux, causing
all dynamically linked applications to fail when run in a container.
Consequently, error when we detect the daemon is being run with SELinux enabled
and the btrfs driver. Documentation has been added for this behavior.

Docker's --sig-proxy option sends all signals but one to a container. The
exception s SIGCHLD, which is deliberately ignored as it doesn't make sense to
send such a signal to a process in a container. Documentation updates will make
this less confusing if anyone does attempt to do this.
