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.

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.

This also removes dead code in the native driver for a past feature that
was never fully implemented.

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.

lxc is special in that we cannot create the master outside of the
container without opening the slave because we have nothing to provide to the
cmd. We have to open both then do the crazy setup on command right now instead of
passing the console path to lxc and telling it to open up that console. we save a couple of
openfiles in the native driver because we can do this.

This uses "," instead of spaces so that the flags are parsed correctly
and also does not do a strings.Split on an empty string because
strings.Split will return a slice with one element, and empty string
causing parsing to fail when it validates that the cap exists.

This patch adds pause/unpause to the command line, api, and drivers
for use on containers. This is implemented using the cgroups/freeze
utility in libcontainer and lxc freeze/unfreeze.

We now have one place that keeps track of (most) devices that are allowed and created within the container. That place is pkg/libcontainer/devices/devices.go
This fixes several inconsistencies between which devices were created in the lxc backend and the native backend. It also fixes inconsistencies between wich devices were created and which were allowed. For example, /dev/full was being created but it was not allowed within the cgroup. It also declares the file modes and permissions of the default devices, rather than copying them from the host. This is in line with docker's philosphy of not being host dependent.
