The ANSI escape codes \e[0A (cursor up 0 lines) and \e[0B (cursor down 0 lines)
are not well defined and are treated differently by different terminals. In
particular xterm treats 0 as a missing parameter and therefore defaults to 1,
whereas rxvt-unicode treats these escapes as a request to move 0 lines.
However the use of these codes is unnecessary and were really just hiding the
fact that we were not correctly computing diff when adding a new line. Having
added the new line to the ids map and output the corresponding \n we need to
then calculate a correct diff of 1 rather than leaving it as the default 0
(which xterm then interprets as 1). The fix is to pull the diff calculation out
of the else case and to always do it.
With this in place we can then avoid outputting escapes for moving 0 lines.
Actually diff should never be 0 to start with any more, but check to be safe.
This fixes corruption of `docker pull` seen with rxvt-unicode (and likely other
terminals in that family) seen in #28111. Tested with rxvt-unicode
($TERM=rxvt-unicode), xterm ($TERM=xterm), mlterm ($TERM=mlterm) and aterm
($TERM=kterm).
The test cases have been updated to match the new behaviour.

This remove a dependency on `go-check` (and more) when using
`pkg/idtools`. `pkg/integration` should never be called from any other
package then `integration`.

In some cases, attempting to `docker cp` to a container's volume dir
would fail due to the volume mounts not existing after performing a
bind-mount on the container path prior to doing a pivot_root.
This does not seem to be effecting all systems, but was found to be a
problem on centos.
The solution is to use an `rbind` rather than `bind` so that any
existing mounts are carried over.
The `MakePrivate` on `path` is no longer neccessary since we are already
doing `MakeRPrivate` on `/`.

When daemon fails to load an authz plugin, it should be removed from

response, resulting in undesired behavior (eg. daemon panic)

containers may specify these cgroup values at runtime. This will allow
processes to change their priority to real-time within the container
when CONFIG_RT_GROUP_SCHED is enabled in the kernel. See #22380.
Also added sanity checks for the new --cpu-rt-runtime and --cpu-rt-period
flags to ensure that that the kernel supports these features and that
runtime is not greater than period.
Daemon will support a --cpu-rt-runtime flag to initialize the parent
cgroup on startup, this prevents the administrator from alotting runtime
to docker after each restart.
There are additional checks that could be added but maybe too far? Check
parent cgroups to ensure values are <= parent, inspecting rtprio ulimit
and issuing a warning.
