In https://github.com/torvalds/linux/commit/5ca3726 (released in v4.7-rc1) the
content of the `cpuacct.usage_percpu` file in sysfs was changed to include both
online and offline cpus. This broke the arithmetic in the stats helpers used by
`docker stats`, since it was using the length of the PerCPUUsage array as a
proxy for the number of online CPUs.
Add current number of online CPUs to types.StatsJSON and use it in the
calculation.
Keep a fallback to `len(v.CPUStats.CPUUsage.PercpuUsage)` so this code
continues to work when talking to an older daemon. An old client talking to a
new daemon will ignore the new field and behave as before.
Fixes#28941.

Server-side rollback can take advantage of the rollback-specific update
parameters, instead of being treated as a normal update that happens to
go back to a previous version of the spec.

Without this fix the error the client might see is:
target is unknown
which wasn't helpful to me when I saw this today. With this fix I
now see:
MediaType is unknown: 'text/html'
which helped me track down the issue to the registry I was talking to.

The overlay(2) drivers were moved up in the list of storage drivers,
and are known to have problems if the backing filesystem does not
support d_type.
Commit 2e20e63da2a8a0ffbbb3f2146f87559e17f43046 added a warning,
which is logged in the daemon logs, however, many users do not
check those logs, and may overlook this warning.
This patch adds the same warning to the output of `docker info`
so that the warning is more easily found.
In addition, the output of warnings printed by `docker info` is
optimized, by;
- moving all warnings to the _end_ of the output, instead of
mixing them with the regular output
- wrapping the storage-driver warnings, so that they are more
easily readable

This fix tries to address the issue raised in 25696 where
it was not possible to specify `--stop-signal` for `docker service create`
and `docker service update`, in order to use special signal to stop
the container.
This fix adds `--stop-signal` and update the `StopSignal` in `Config`
through `service create` and `service update`.
Related docs has been updated.
Integration test has been added.
This fix fixes 25696.
