The Golang built-in gzip library is serialized, and fairly slow
at decompressing. It also only decompresses on demand, versus
pipelining decompression.
This change switches to using the pigz external command
for gzip decompression, as opposed to using the built-in
golang one. This code is not vendored, but will be used
if it autodetected as part of the OS.
This also switches to using context, versus a manually
managed channel to manage cancellations, and synchronization.
There is a little bit of weirdness around manually having
to cancel in the error cases.

go1.8.5 (released 2017/10/25) includes fixes to the compiler, linker, runtime,
documentation, go command, and the crypto/x509 and net/smtp packages. It
includes a fix to a bug introduced in Go 1.8.4 that broke go get of non-Git
repositories under certain conditions. See the Go 1.8.5 milestone on our issue
tracker for details:

The main gain here is that they all use exactly the same distro; previously
arm64 was using Ubuntu Xenial because Debian jessie was too old.
Does not seem that we can change any of the downloaded dependencies still,
as eg libseccomp is still not the version we are using.

With docker-17.06.0 some images pulled do not extract properly. Some files don't appear in correct directories. This may or may not cause the pull to fail. These images can't be pushed or saved. 17.06 is the first version of Docker built with go1.8.
Cause
There are multiple updates to the tar package in go1.8.
https://go-review.googlesource.com/c/32234/ disables using "prefix" field when new tar archives are being written. Prefix field was previously set when a record in the archive used a path longer than 100 bytes.
Another change https://go-review.googlesource.com/c/31444/ makes the reader ignore the "prefix" field value if the record is in GNU format. GNU format defines that same area should be used for access and modified times. If the "prefix" field is not read, a file will only be extracted by the basename.
The problem is that with a previous version of the golang archive package headers could be written, that use the prefix field while at the same time setting the header format to GNU. This happens when numeric fields are big enough that they can not be written as octal strings and need to be written in binary. Usually, this shouldn't happen: uid, gid, devmajor, devminor can use up to 7 bytes, size and timestamp can use 11. If one of the records does overflow it switches the whole writer to GNU mode and all next files will be saved in GNU format.

Starting with this commit, integration tests should no longer rely on
the docker cli, they should be API tests instead. For the existing tests
the scripts will use a frozen version of the docker cli with a
DOCKER_API_VERSION frozen to 1.30, which should ensure that the CI remains
green at all times.
To help contributors develop and test manually with a modified docker
cli, this commit also adds a DOCKER_CLI_PATH environment variable to the
Makefile. This allows to set the path of a custom cli that will be
available inside the development container and used to run the
integration tests.

This drops support for migrations from pre-1.10 Docker versions, which
should be done via an external tool or an intermediate upgrade.

There is no reason to duplicate efforts and tini is well built and
better than grimes. It is a much stronger option for the default init
and @krallin has done a great job maintaining it and helping make
changes so that it will work with Docker.

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);
}
```

> Cheers,
> Chris on behalf of the Go team

the man/Dockerfile is not yet updated, because
