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);
}
```

We finally have a s390x binary tarball for go on "storage.googleapis.com".
So use this instead of bootstrapping with gccgo.

With golang version 1.7 the s390x architecture is officially supported.
To be in sync with the other architectures now switch also for s390x
from gccgo 6.1 to golang:
- golang: build and install to /usr/src/go
* Download golang-1.7 sources
* Bootstrap with gccgo 6.1
- go lint: Sync GO_LINT_COMMIT with other Dockerfiles
- notary: Remove GO15VENDOREXPERIMENT and softlink hack
With this patch the current CI on s390x completes with:
- OK: 1375 passed, 43 skipped

We have to wait until runc version (RUNC_COMMIT) is bumped.
Otherwise we get the following error:

To implement seccomp for s390x the following changes are required:
1) seccomp_default: Add s390 compat mode
On s390x (64 bit) we can run s390 (32 bit) programs in 32 bit
compat mode. Therefore add this information to arches().
2) seccomp_default: Use correct flags parameter for sys_clone on s390x
On s390x the second parameter for the clone system call is the flags
parameter. On all other architectures it is the first one.
See kernel code kernel/fork.c:
#elif defined(CONFIG_CLONE_BACKWARDS2)
SYSCALL_DEFINE5(clone, unsigned long, newsp, unsigned long, clone_flags,
int __user *, parent_tidptr,
So fix the docker default seccomp rule and check for the second
parameter on s390/s390x.
3) seccomp_default: Add s390 specific syscalls
For s390 we currently have three additional system calls that should
be added to the seccomp whitelist:
- Other architectures can read/write unprivileged from/to PCI MMIO memory.
On s390 the instructions are privileged and therefore we need system
calls for that purpose:
* s390_pci_mmio_write()
* s390_pci_mmio_read()
- Runtime instrumentation:
* s390_runtime_instr()
4) test_integration: Do not run seccomp default profile test on s390x
The generated profile that we check in is for amd64 and i386
architectures and does not work correctly on s390x.
See also: 75385dc216 ("Do not run the seccomp tests that use
default.json on non x86 architectures")
5) Dockerfile.s390x: Add "seccomp" to DOCKER_BUILDTAGS

Pull request #22840 and commit 40b21745cc ("Upgrade to golang 1.6.2")
introduces gcc 6.1 for Dockerfile.gccgo and Dockerfile.ppc64le.
So do this also for s390x and use "s390x/gcc:6.1" as base image.
In addition to this use "GO15VENDOREXPERIMENT=0" for notary build
as a workaround for:
* golang/go#15814
* golang/go#15628

"$GOPATH/src/github.com/opencontainers/runc" && git checkout -q

Godeps/_workspace/src/github.com/seccomp/libseccomp-golang/seccomp.go:25:22:
fatal error: seccomp.h: No such file or directory
// #include <seccomp.h>
The problem is that the installed libseccomp version in trusty is too old.
Fix this and install version 2.3.0 of libseccomp like it is done in the
x86 Dockerfile.

This change adds file version information to docker.exe and dockerd.exe by
adding a Windows version resource with the windres tool.
This change adds a dependency to binutils-mingw-w64 on Linux, but removes
a dependency on rsrc. Most Windows build environments should already have
windres if they have gcc (which is necessary to build dockerd).
