When working with Go channels you must not set it to nil or else the
channel will block forever. It will not panic reading from a nil chan
but it blocks. The correct way to do this is to create the channel then
close it as the correct results to the caller will be returned.

container.
docker run -v /dev:/dev should stop mounting other default mounts in i
libcontainer otherwise directories and devices like /dev/ptx get mishandled.
We want to be able to run libvirtd for launching vms and it needs
access to the hosts /dev. This is a key componant of OpenStack.

This ensures that the libcontainer state is fully removed for a

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.

This fixes various tests by checking for non zero exit code, accounting for lxc-specific base-diffs, and by removing lxc specific environment vars.
It also adds the --share-ipc option to lxc-start for shared ipc namespaces.
