When we tag an Image with several names and we run one of them,
The "create" job will log this event with
+job log(create, containerID, Imagename).
And the "Imagename" is always the first one (sorted). It is the
same to "start/stop/rm" jobs. So use the correct name instand.

I have seen a lot of people try to do this and reach out to me on how to mount
/dev/snd because it is returning "not a device node". The docs imply you can
_just_ mount /dev/snd and that is not the case. This fixes that. It also allows
for coolness if you want to mount say /dev/usb.

Do not remove container if any of the resource could not be cleaned up. We
don't want to leak resources.
Two new states have been created. RemovalInProgress and Dead. Once container
is Dead, it can not be started/restarted. Dead container signifies the
container where we tried to remove it but removal failed. User now needs to
figure out what went wrong, corrent the situation and try cleanup again.
RemovalInProgress signifies that container is already being removed. Only
one removal can be in progress.
Also, do not allow start of a container if it is already dead or removal is
in progress.
Also extend existing force option (-f) to docker rm to not return an error
and remove container from user view even if resource cleanup failed.
This will allow a user to get back to old behavior where resources
might leak but atleast user will be able to make progress.

Cgroup resources are host dependent, they should be in hostConfig.
For backward compatibility, we just copy it to hostConfig, and leave it in
Config for now, so there is no regressions, but the right way to use this
throught json is to put it in HostConfig, like:
{
"Hostname": "",
...
"HostConfig": {
"CpuShares": 512,
"Memory": 314572800,
...
}
}
As we will add CpusetMems, CpusetCpus is definitely a better name, but some
users are already using Cpuset in their http APIs, we also make it compatible.
The main idea is keep using Cpuset in Config Struct, and make it has the same
value as CpusetCpus, but not always, some scenarios:
- Users use --cpuset in docker command, it can setup cpuset.cpus and can
get Cpuset field from docker inspect or other http API which will get
config info.
- Users use --cpuset-cpus in docker command, ditto.
- Users use Cpuset field in their http APIs, ditto.
- Users use CpusetCpus field in their http APIs, they won't get Cpuset field
in Config info, because by then, they should already know what happens
to Cpuset.

Currently when containers are linked the alias name (e.g. from `--link
name:alias`) is added to the parent container's `/etc/hosts` with a
reference to the IP of the linked container. Some software requires
using the official hostname or node name in operations that need to
match on those values, and it is therefore helpful if the parent
container can refer to the child/link using those same values and still
access the same IP.

Since the separator for extra host settings (for /etc/hosts in a
container) is a ":", the code that handles extra hosts needed to only
split on the first ":" to preserve IPv6 addresses which are passed via
the command line settings as well as stored in the JSON container
config.

Addresses #5811
This cleans up an error in the logic which removes localhost resolvers
from the host resolv.conf at container creation start time. Specifically
when the determination is made if any nameservers are left after
removing localhost resolvers, it was using a string match on the word
"nameserver", which could have been anywhere (including commented out)
leading to incorrect situations where no nameservers were left but the
default ones were not added.
This also adds some complexity to the regular expressions for finding
nameservers in general, as well as matching on localhost resolvers due
to the recent addition of IPv6 support. Because of IPv6 support now
available in the Docker daemon, the resolvconf code is now aware of
IPv6 enable/disable state and uses that for both filter/cleaning of
nameservers as well as adding default Google DNS (IPv4 only vs. IPv4
and IPv6 if IPv6 enabled). For all these changes, tests have been
added/strengthened to test these additional capabilities.

Fixes#9709
In cases where the volumes-from container is removed and the consuming
container is restarted, docker was trying to re-apply volumes from that
now missing container, which is uneccessary since the volumes are
already applied.
Also cleaned up the volumes-from parsing function, which was doing way more than
it should have been.

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

This fixes the container start issue for containers which were started
on a daemon prior to the resolv.conf updater PR. The update code will
now safely ignore these containers (given they don't have a sha256 hash
to compare against) and will not attempt to update the resolv.conf
through their lifetime.
