Docker 1.11 added a feature to set labels on volumes,
networks and images (during build), but these changes
were not documented in the API documentation.
This adds the new features to the documentation.
Also fixes some minor formatting, and options that
were not used in the examples.

The "registry" query-param was in added 10c0e99037,
and removed in docker 0.5.0 via 66a9d06d9f.
Aparently, it was never removed from the documentation,
and included in all versions of the API docs.
This removes it from the documentation.

The `Status` field is a `map[string]interface{}` which allows the driver to pass
back low-level details about the underlying volume.

People have reported following problem.
- docker run -ti --name=foo -v /dev/:/dev/ fedora bash
- docker cp foo:/bin/bash /tmp
Once the cp operation is complete, it unmounted /dev/pts on the host. /dev/pts
is a submount of /dev/. This is completely unexpected. Following is the
reson for this behavior.
containerArchivePath() call mountVolumes() which goes through all the mounts
points of a container and mounts them in daemon mount namespace in
/var/lib/docker/devicemapper/mnt/<containerid>/rootfs dir. And once we have
extracted the data required, these are unmounted using UnmountVolumes().
Mounts are done using recursive bind (rbind). And these are unmounted using
lazy mount option on top level mount. (detachMounted()). That means if there
are submounts under top level mounts, these mount events will propagate and
they were "shared" mounts with host, it will unmount the submount on host
as well.
For example, try following.
- Prepare a parent and child mount point.
$ mkdir /root/foo
$ mount --bind /root/foo /root/foo
$ mount --make-rshared /root/foo
- Prepare a child mount
$ mkdir /root/foo/foo1
$ mount --bind /root/foo/foo1 /root/foo/foo1
- Bind mount foo at bar
$ mkdir /root/bar
$ mount --rbind /root/foo /root/bar
- Now lazy unmount /root/bar and it will unmount /root/foo/foo1 as well.
$ umount -l /root/bar
This is not unintended. We just wanted to unmount /root/bar and anything
underneath but did not have intentions of unmounting anything on source.
So far this was not a problem as docker daemon was running in a seprate
mount namespace where all propagation was "slave". That means any unmounts
in docker daemon namespace did not propagate to host namespace.
But now we are running docker daemon in host namespace so that it is possible
to mount some volumes "shared" with container. So that if container mounts
something it propagates to host namespace as well.
Given mountVolumes() seems to be doing only temporary mounts to read some
data, there does not seem to be a need to mount these shared/slave. Just
mount these private so that on unmount, nothing propagates and does not
have unintended consequences.

This test was flaky on ppc64le, where the average time to close was
around 1 second. This bumps that timeout to 60 seconds which should be
plently.

Running on kernel versions older than 3.10 has not been
supported for a while (as it's known to be unstable).
With the containerd integration, this has become more
apparent, because kernels < 3.4 don't support PR_SET_CHILD_SUBREAPER,
which is required for containerd-shim to run.
Change the previous "warning" to a "fatal" error, so
that we refuse to start.
There's still an escape-hatch for users by setting
"DOCKER_NOWARN_KERNEL_VERSION=1" so that they can
run "at their own risk".

Auto-creation of non-existing host directories
is no longer deprecated (9d5c26bed2),
so this warning is no longer relevant.
This removes the deprecation warning.
Also removes the "system" package here, because it's only used
on non-Windows, so basically just called os.MkdirAll()

If contaner start fail of (say) "command not found", the container
actually didn't start at all, we shouldn't log start and die event for
it, because that doesnt actually happen.

If a build context tar has path names of the form 'x/./y', they will be
stored in this unnormalized form internally by tarsum. When the builder
walks the untarred directory tree and queries hashes for each relative
path, it will query paths of the form 'x/y', and they will not be found.
To correct this, have tarsum normalize path names by calling Clean.
Add a test to detect this caching false positive.

Distro packagers will often use the tarball to build a package and have
the build script for the package in git. To avoid that the docker build
script picks up the git commit from the distro repo we also check for a
directory named .git before check for -unsupported builds.

This feature was added after the 1.11 code-freeze,
so will be part of the 1.12 release. Moving it to the
right API version.
