See #10141 for more info, but the main point of this is to make sure
that if you do "docker run -e FOO ..." that FOO from the current env
is passed into the container. This means that if there's a value, its
set. But it also means that if FOO isn't set then it should be unset in
the container too - even if it has to remove it from the env. So,
unset HOSTNAME
docker run -e HOSTNAME busybox env
should _NOT_ show HOSTNAME in the list at all

This adds the output of a "Backing Filesystem:" entry to `docker info`
to overlay, aufs, and devicemapper graphdrivers. The default list
includes a fairly complete list of common filesystem names from
linux/include/uapi/linux/magic.h, but if the backing filesystem is not
recognized, the code will simply show "<unknown>"

The documentation on `docker export` doesn't mention that
data in volumes is not included in the export.
This adds a note that volumes are not part of the export
and refers to the "Backup, restore, or migrate data volumes"
to give the user some pointers.

Add a --readonly flag to allow the container's root filesystem to be
mounted as readonly. This can be used in combination with volumes to
force a container's process to only write to locations that will be
persisted. This is useful in many cases where the admin controls where
they would like developers to write files and error on any other
locations.

We want to be able to use container without the PID namespace. We basically
want containers that can manage the host os, which I call Super Privileged
Containers. We eventually would like to get to the point where the only
namespace we use is the MNT namespace to bring the Apps userspace with it.
By eliminating the PID namespace we can get better communication between the
host and the clients and potentially tools like strace and gdb become easier
to use. We also see tools like libvirtd running within a container telling
systemd to place a VM in a particular cgroup, we need to have communications of the PID.
I don't see us needing to share PID namespaces between containers, since this
is really what docker exec does.
So currently I see us just needing docker run --pid=host

--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.

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.
```

> tar tf ./bundle.tar | wc -l
42
> tar xOf ./bundle.tar repositories
{"busybox":{"latest":"2d8e5b282c81244037eb15b2068e1c46319c1a42b80493acb128da24b2090739"},"fedora":{"latest":"58394af373423902a1b97f209a31e3777932d9321ef10e64feaaa7b4df609cf9"},"ubuntu":{"lucid":"9cc9ea5ea540116b89e41898dd30858107c1175260fb7ff50322b34704092232","saucy":"9f676bd305a43a931a8d98b13e5840ffbebcd908370765373315926024c7c35e"}}

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.
