We already bumped this for Dockerfile, should keep build environment
consistent with that.

We should not check if the mux framework internals work as expected in every handler.
The missing parameter error doesn't make sense from the user point of view.
This change initializes a proper vars context if the mux fails to do so and delegates
specific parameter error checks to the handlers.

The race is between pools.Put which calls buf.Reset and exec.Cmd
doing io.Copy from the buffer; it caused a runtime crash, as
described in #16924:
``` docker-daemon cat the-tarball.xz | xz -d -c -q | docker-untar /path/to/... (aufs ) ```
When docker-untar side fails (like try to set xattr on aufs, or a broken
tar), invokeUnpack will be responsible to exhaust all input, otherwise
`xz` will be write pending for ever.
this change add a receive only channel to cmdStream, and will close it
to notify it's now safe to close the input stream;
in CmdStream the change to use Stdin / Stdout / Stderr keeps the
code simple, os/exec.Cmd will spawn goroutines and call io.Copy automatically.
the CmdStream is actually called in the same file only, change it
lowercase to mark as private.

When running LXC dind (outer docker is started with native driver)
cgroup paths point to `/docker/CID` inside `/proc/self/mountinfo` but
these paths aren't mounted (root is wrong). This fix just discard the
cgroup dir from mountinfo and set it to root `/`.
This patch fixes/skip OOM LXC tests that were failing.

On LXC memory swap was only set to memory_limit*2 even if a value for
memory swap was provided. This patch fix this behavior to be the same
as the native driver and set correct memory swap in the template.
Also add a test specifically for LXC but w/o adding a new test
requirement.
