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.

This fix updates the `docs/api/version-history.md`
for `ReadOnly` parameter, which is now available in
`POST /services/create` and `POST /services/(id or name)/update`.
This fix is a follow up to 30162.

Pulling all the endpoints is a very resource heavy operation especially
for Global-scoped networks with a backing KVStore. Such heavy operations
can be fetched for individual network inspect. These are unneccessary
for a simple network list operation.

This allows the user to set a logging mode to "blocking" (default), or
"non-blocking", which uses the ring buffer as a proxy to the real log
driver.
This allows a container to never be blocked on stdio at the cost of
dropping log messages.
Introduces 2 new log-opts that works for all drivers, `log-mode` and
`log-size`. `log-mode` takes a value of "blocking", or "non-blocking"
I chose not to implement this as a bool since it is difficult to
determine if the mode was set to false vs just not set... especially
difficult when merging the default daemon config with the container config.
`log-size` takes a size string, e.g. `2MB`, which sets the max size
of the ring buffer. When the max size is reached, it will start
dropping log messages.

This fix tries to address the issue raised in 28176 where
text frame was used in websocket attach endpoint. In case
the data send out contains non utf8 data, the connection
will be closed in certain browsers, e.g., Safari.
This fix address the issue by change `PayloadType` to `BinaryFrame`.
This fix is tested manually with Safari. The docker daemon is inside a Linux Virtual Machine.
Create a container with:
```
docker run -itd --name websocket busybox sh -c "while true; do echo -e 'he\\xc3\\x28o'; sleep 5; done"
```
Use the following url (172.16.66.128:2375 is the tcp address of the daemon):
```
file:///websocket.html?url=ws://172.16.66.128:2375/v1.25/containers/websocket/attach/ws?logs=1&stderr=1&stdout=1&stream=1&stdin=1
```
and the following html:
```
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Websocket</title>
<script type="text/javascript">
function DockerWebSocket() {
if ("WebSocket" in window) {
console.log("WebSocket is supported by Browser...")
// Remove '?url=' prefix
url = window.location.search.replace(/^(\?url=)/,"");
console.log("URL ["+url+"]...");
var ws = new WebSocket(url);
ws.onopen = function() {
console.log("Connection is opened...");
};
ws.onclose = function() {
console.log("Connection is closed...");
};
ws.onmessage = function (e) {
if (typeof e.data === "string") {
alert("WebSocket received text message ["+e.data+"]!")
} else {
console.log("Message is received...")
var blobReader = new FileReader();
blobReader.onload = function(event) {
console.log(JSON.stringify(blobReader.result))
};
blobReader.readAsText(e.data)
console.log("Message complete...")
}
};
} else {
alert("WebSocket is not supported by Browser!");
}
}
</script>
</head>
<body>
<div>
<a href="javascript:DockerWebSocket()">Run DockerWebSocket</a>
</div>

At the "Build image from Dockerfile" section in the API docs
the Content-Type header is missing.
In addition, some parts in the code are still setting the
Content-Type header to application/tar while it was changed
to application/x-tar since 16th September 2015.
