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.

If stop/kill command hits a short window between process' exit and
container's cleanup, it will no longer fail with 'no such process'
error.
