init layer is read/write layer and not read only layer. Following commit
introduced new graph driver method CreateReadWrite.
ef5bfad Adding readOnly parameter to graphdriver Create method
So far only windows seem to be differentiating between above two methods.
Making this change to make sure -init layer calls right method so that
we don't have surprises in future.
Windows does not need init layer. This patch also gets rid of creation of
init layer on windows.

As part of making graphdrivers support pluginv2, a PluginGetter
interface was necessary for cleaner separation and avoiding import
cycles.
This commit creates a PluginGetter interface and makes pluginStore
implement it. Then the pluginStore object is created in the daemon
(rather than by the plugin manager) and passed to plugin init as
well as to the different subsystems (eg. graphdrivers, volumedrivers).
A side effect of this change was that some code was moved out of
experimental. This is good, since plugin support will be stable soon.

This renames `MaximumIOps` to `IOMaximumBandwidth`,
and `MaximumIOBps` to `IOMaximumIOps` to match

This adds a small C binary for fighting zombies. It is mounted under
`/dev/init` and is prepended to the args specified by the user. You
enable it via a daemon flag, `dockerd --init`, as it is disable by
default for backwards compat.
You can also override the daemon option or specify this on a per
container basis with `docker run --init=true|false`.
You can test this by running a process like this as the pid 1 in a
container and see the extra zombie that appears in the container as it
is running.
```c
int main(int argc, char ** argv) {
pid_t pid = fork();
if (pid == 0) {
pid = fork();
if (pid == 0) {
exit(0);
}
sleep(3);
exit(0);
}
printf("got pid %d and exited\n", pid);
sleep(20);
}
```

Allows the user to use `pretty` as the format string.
This enables users to put custom format options into their CLI config
just like is supported for `docker ps` and `docker images`

These installation procedures are very similar, so
synchronized these docs and removed some differences.
Also;
- updated markdown, added language-hints where possible
- replaced "service docker start" with "systemctl start"
- replaced "chkconfig docker on" with "systemctl enable"
- added "systemctl enable" to the list of steps for
installation, because most people want to have docker
started automatically (and overlooked this step).

This package doesn't really seem to do anything of real interest.
Removing it and replacing with a few helper functions. Most of this was
maintaining a fork of ctxhttp to support a mock that was unnecessary.
We could probably do with a further refactor of the client interface.
There is a lot of confusion of between transport, http layer and
application layer that makes for some awkward code. This change
improves the situation to the point where no breaking changes are
introduced.

The regex used to describe the max-file and max-size logging options for
the json-file logger were incorrect. The regexes would only match a
single character (a digit or a literal +). Instead the regexes should
match 1 or more digits.
The character class for the units of the max-size also included a pipe
which meant that the regex would match 1| instead of only matching 1m,
1k, and 1g.
