Qiang Huang 837eec064d move resources from Config to HostConfig
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.

Abin Shahab 3ca5af6b1a Adds ipc namespace capability to lxc, and fixes tests.
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.

Vishnu Kannan f96e04ffc7 This patch adds ability in docker to detect out of memory conditions in containers.
Since the containers can handle the out of memory kernel kills gracefully, docker
will only provide out of memory information as an additional metadata as part of
container status.

container with tty using lxc driver with fail with error

template: lxc:60:20: executing "lxc" at <.Console>: Console is not a field of
struct type struct { *execdriver.Command; AppArmor bool; ProcessLabel string; MountLabel string }

Michael Crosby 7321067176 Use argv0 as reexec implementation for dockerinit
This changes the way the exec drivers work by not specifing a -driver
flag on reexec.  For each of the exec  drivers they register their own
functions that will be matched aginst the argv 0 on exec and called if
they match.

This also allows any functionality to be added to docker so that the
binary can be reexec'd and any type of function can be called.  I moved
the flag parsing on docker exec to the specific initializers so that the
implementations do not bleed into one another.  This also allows for
more flexability within reexec initializers to specify their own flags
and options.
