This adds an `--oom-score-adjust` flag to the daemon so that the value
provided can be set for the docker daemon's process. The default value
for the flag is -500. This will allow the docker daemon to have a
less chance of being killed before containers do. The default value for
processes is 0 with a min/max of -1000/1000.
-500 is a good middle ground because it is less than the default for
most processes and still not -1000 which basically means never kill this
process in an OOM condition on the host machine. The only processes on
my machine that have a score less than -500 are dbus at -900 and sshd
and xfce( my window manager ) at -1000. I don't think docker should be
set lower, by default, than dbus or sshd so that is why I chose -500.

The "none" option was not added to the documentation.
This adds an example, and adds additional information
on manually accepting or rejecting a node.

Add a `--network` flag which replaces `--net` without deprecating it
yet. The `--net` flag remains hidden and supported.

Looks like there's issues with sourceforge project
pages. Given that sourceforge isn't really what
it used to be, trying to find alternative URLs
where possible.

Flatten the list of `docker run` flags and group them loosely by
category (general purpose, security, networking, ...).

Kernel memory is not allowed to be updated if container is
running, it's not actually a precise kernel limitation.
Before kernel version 4.6, kernel memory will not be accounted
until kernel memory limit is set, if a container created with
kernel memory initialized, kernel memory is accounted as soon
as process created in container, so kernel memory limit update
is allowed afterward. If kernel memory is not initialized,
kernel memory consumed by processes in container will not be
accounted, so we can't update the limit because the account
will be wrong.
So update kernel memory of a running container with kernel memory
initialized is allowed, we should soften the limitation by docker.

If the remote registry responds with a NAME_UNKNOWN error, treat this as
a fatal error and don't retry the push.

The `--pid` flag was added in Docker 1.5.0, but the
API changes were not documented. In Docker 1.12.0,
`--pid=container:<name|id>` was added as an additional
option, but also undocumented.
This adds the missing API documentation for this
option.
Also see commits
47e3da848f (for 1.5.0), and
ebeb5a0422 (for 1.12.0).
