- Optional "--shm-size=" was added to the sub-command(run, create,and build).
- The size of /dev/shm in the container can be changed
when container is made.
- Being able to specify is a numerical value that applies number,
b, k, m, and g.
- The default value is 64MB, when this option is not set.
- It deals with both native and lxc drivers.

The LXC driver was deprecated in Docker 1.8.
Following the deprecation rules, we can remove a deprecated feature
after two major releases. LXC won't be supported anymore starting on Docker 1.10.

Memory swappiness option takes 0-100, and helps to tune swappiness
behavior per container.
For example, When a lower value of swappiness is chosen
the container will see minimum major faults. When no value is
specified for memory-swappiness in docker UI, it is inherited from
parent cgroup. (generally 60 unless it is changed).

By convention /pkg is safe to use from outside the docker tree, for example
if you're building a docker orchestrator.
/nat currently doesn't have any dependencies outside of /pkg, so it seems
reasonable to move it there.
This rename was performed with:
```
gomvpkg -vcs_mv_cmd="git mv {{.Src}} {{.Dst}}" \
-from github.com/docker/docker/nat \
-to github.com/docker/docker/pkg/nat
```

This commit also brings in the ability to specify a default network and its
corresponding driver as daemon flags. This helps in existing clients to
make use of newer networking features provided by libnetwork.

- Updated Dockerfile to satisfy libnetwork GOPATH requirements.
- Reworked daemon to allocate network resources using libnetwork.
- Reworked remove link code to also update network resources in libnetwork.
- Adjusted the exec driver command population to reflect libnetwork design.
- Adjusted the exec driver create command steps.
- Updated a few test cases to reflect the change in design.
- Removed the dns setup code from docker as resolv.conf is entirely managed
in libnetwork.
- Integrated with lxc exec driver.

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.

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.
