TestCaptureTestFunc failed in localunittest:
# make localunittest
=== RUN TestCaptureTestFunc
--- FAIL: TestCaptureTestFunc (0.00s)
capture_test.go:26: expected package "github.com/opencontainers/runc/libcontainer/stacktrace" but received "_/root/runc/libcontainer/stacktrace"
#
Reason: the path for stacktrace is a fixed string which
only valid for container environment.
And we can switch to relative path to make both in-container
and out-of-container test works.
After patch:
# make localunittest
=== RUN TestCaptureTestFunc
--- PASS: TestCaptureTestFunc (0.00s)

Removed a lot of clutter, improved the style of the code, removed
unnecessary complexity. In addition, made errors unique by making bail()
exit with a unique error code. Most of this code comes from the current
state of the rootless containers branch.

This device is not required by the OCI spec.
The rationale for this was linked to https://github.com/docker/docker/issues/2393
So a non functional /dev/fuse was created, and actual fuse use still is
required to add the device explicitly. However even old versions of the JVM
on Ubuntu 12.04 no longer require the fuse package, and this is all not
needed.

/proc/timer_list seems to leak information about the host. Here is
an example from a busybox container running on docker+kubernetes.
# cat /proc/timer_list | grep -i -e kube

On older kernels or kernels were CONFIG_MEMCG_KMEM is not set some cgroup tests
cannot be run. We simply test for the existence of the file
"${CGROUP_BASE_PATH}/memory/memory.kmem.limit_in_bytes" which should be
sufficient to conclude that CONFIG_MEMCG_KMEM is not set.

It's possible that `cmd.Process` is still nil when we reach timeout.
Start creates `Process` field synchronously, and there is no way to such
race.

This avoid the goimports tool from remove the libcontainer/keys import line due the package name is diferent from folder name

Back quotes are the placeholder feature described here:
https://github.com/urfave/cli#placeholder-values
Without this, cli will take `-1` as default value as:
```
--memory-swap -1 Total memory usage (memory + swap); set `-1` to enable unlimited swap
```
After this patch, it'll act correctly
```
--memory-swap value Total memory usage (memory + swap); set '-1' to enable unlimited swap
```

Revert: #935Fixes: #946
I can reproduce #946 on some machines, the problem is on
some machines, it could be very fast that modify time
of `memory.kmem.limit_in_bytes` could be the same as
before it's modified.
And now we'll call `SetKernelMemory` twice on container
creation which cause the second time failure.
Revert this before we find a better solution.
