Tim Smith 69a75c673c Add daemon flag to specify public registry mirrors 
Adds support for a --registry-mirror=scheme://<host>[:port]
daemon flag. The flag may be present multiple times. If
provided, mirrors are prepended to the list of endpoints used
for image pull. Note that only mirrors of the public
index.docker.io registry are supported, and image/tag resolution
is still performed via the official index.

Daniel, Dao Quang Minh 4b3b54ca38 fix console attribute in lxc template 
commit 4aa5da278f moves `Console` from Command to
ProcessConfig, but missed the change in lxc_template. Therefore creating a
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 }

This changes lxc_console template to refers to `.ProcessConfig.Console`

Dan Walsh 73617e5e18 Change default label of container volumes to shared SELinux Label 
Since these will be shared between containers we want to label
them as svirt_sandbox_file_t:s0.  That will allow multiple containers
to write to them.

Currently we are allowing container domains to read/write all content in
/var/lib/docker because of container volumes.  This is a big security hole
in our SELinux story.

This patch will allow us to tighten up the security of docker containers.

Michael Crosby b4e2f5ed96 Move userland proxies out of daemon's process 
This PR moves the userland proxies for TCP and UDP traffic out of the
main docker daemon's process ( from goroutines per proxy ) to be a
separate reexec of the docker binary.  This reduces the cpu and memory
needed by the daemon and if the proxy processes crash for some reason
the daemon is unaffected.  This also displays in the standard process
tree so that a user can clearly see if there is a userland proxy that is
bound to a certain ip and port.

This also helps us to cleanly cleanup the proxy processes by stopping
these commands instead of trying to terminate a goroutine.

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.
