I was able to successfully use device mapper autoconfig feature
(commit 5ef07d79c) but it stopped working after a reboot.
Investigation shown that the dm device was not activated because of
a missing binary, that is not used during initial setup, but every
following time. Here's an error shown when trying to manually activate
the device:
> kir@kd:~/go/src/github.com/docker/docker$ sudo lvchange -a y /dev/docker/thinpool
> /usr/sbin/thin_check: execvp failed: No such file or directory
> Check of pool docker/thinpool failed (status:2). Manual repair required!
Surely, there is no solution to this other than to have a package that
provides the thin_check binary installed beforehand. Due to the fact
the issue revealed itself way later than DM setup was performed, it was
somewhat harder to investigate.
With this in mind, let's check for binary presense before setting up DM,
refusing to proceed if the binary is not there, saving a user from later
frustration.
While at it, eliminate repeated binary checking code. The downside is
that the binary lookup is happening more than once now -- I think the
clarity of code overweights this minor de-optimization.

I tried using dm.directlvm_device but it ended up with the following
error:
> Error starting daemon: error initializing graphdriver: error
> writing docker thinp autoextend profile: open
> /etc/lvm/profile/docker-thinpool.profile: no such file or directory
The reason is /etc/lvm/profile directory does not exist. I think it is
better to try creating it beforehand.

- Remove unused function and variables from the package
- Remove usage of it from `profiles/apparmor` where it wasn't required
- Move the package to `daemon/logger/templates` where it's only used

Current insider builds of Windows have support for mounting individual
named pipe servers from the host to the guest. This allows, for example,
exposing the docker engine's named pipe to a container.
This change allows the user to request such a mount via the normal bind
mount syntax in the CLI:
docker run -v \\.\pipe\docker_engine:\\.\pipe\docker_engine <args>

While convention states that Dockerfile instructions should be
written in uppercase, the engine allows them to be mixed case or in
lowercase. The tmLanguage file should tolerate this and provide
highlighting support even if instructions are not written in
uppercase.

- When a network is created with the null ipam driver, docker api server
thread will deference a nil pointer on `docker network ls` and on
`docker network inspect <nw>`. This because buildIpamResource()
assumes a gateway address is always present, which is not correct.

This changes the graphdriver to perform dynamic sandbox management.
Previously, as a temporary 'hack', the service VM had a prebuilt
sandbox in it. With this change, management is under the control
of the client (docker) and executes a mkfs.ext4 on it. This enables
sandboxes of non-default sizes too (a TODO previously in the code).
It also addresses https://github.com/moby/moby/pull/33969#discussion_r127287887
Requires:
- go-winio: v0.4.3
- opengcs: v0.0.12
- hcsshim: v0.6.x
The BSD and Solaris versions of term.MakeRaw already set VMIN and VTIME
explicitly such that a read returns when one character is available.
cfmakeraw (which was previously used) in glibc also sets these values
explicitly, so it should be done in the Linux version of MakeRaw as well
to be consistent.
