746b307c72 Move all bind-mounts in the container inside the namespace 
This moves the bind mounts like /.dockerinit, /etc/hostname, volumes,
etc into the container namespace, by setting them up using lxc.

This is useful to avoid littering the global namespace with a lot of
mounts that are internal to each container and are not generally
needed on the outside. In particular, it seems that having a lot of
mounts is problematic wrt scaling to a lot of containers on systems
where the root filesystem is mounted --rshared.

Note that the "private" option is only supported by the native driver, as
lxc doesn't support setting this. This is not a huge problem, but it does
mean that some mounts are unnecessarily shared inside the container if you're
using the lxc driver.

957f74b876 Add env var to toggle pivot root or ms_move 
Use the  DOCKER_RAMDISK env var to tell the native driver not to use
a pivot root when setting up the rootfs of a container.
