runc is not supported on FreeBSD, so remove all FreeBSD specific bits.

Selinux related code has been moved to the selinux package
(https://github.com/opencontainers/selinux) and therefore xattr related
code can be deleted from libcontainer

Currently, unit test can't be done on arm64 platform
due to multi-arch issue.
Fix points:
golang:1.8.0 doesn't support arm64.
We use golang:1.8 to replace it.

When running runc tests with temp directory with size 500M copying
busybox without preserving hardlinks causes the folder to inflate to
roughly 330M. Copying busybox twice in certain tests causes the /tmp
directory to overfill. Using `-a` preserves links which busybox uses to
implement its choice of binary to run.

runc shouldn't depend on docker and be more self-contained.
Removing github.com/pkg/symlink dep is the first step to not depend on docker anymore

Since the defined config.json contains kmem settings, the test will try
writing to memory.kmem.* and fail. Therefore, it needs to require
cgroups_kmem.

Previously we weren't testing that detached io works properly -- which
will be quite important in the case for rootless containers.

Previously we would handle the "unmapped stdio" case by just doing a
simple check, however this didn't handle cases where the overflow_uid
was actually mapped in the user namespace. Instead of doing some
userspace checks, just try to do the fchown(2) and ignore EINVAL
(unmapped) or EPERM (lacking privilege over inode) errors.

Multiple conditions were previously allowed to be placed upon the
same syscall argument. Restore this behavior.

This fixes a GetStats() issue introduced in #1590:
If Intel RDT is enabled by hardware and kernel, but intelRdt is not
specified in original config, GetStats() will return error unexpectedly
because we haven't called Apply() to create intelrdt group or attach
tasks for this container. As a result, runc events command will have no
output.

The Major and Minor functions were added for Linux in golang/sys@85d1495
which is already vendored in. Use these functions instead of the local
re-implementation.

This allows runc to be used as a target for docker's reexec module that
depends on a correct argv0 to select which process entrypoint to invoke.
Without this patch, when runc re-execs argv0 is set to "/proc/self/exe"
and the reexec module doesn't know what to do with it.

This ensures that we don't hard-code the set of cgroups on the host, as
well as making the permissions granted by rootless.sh much more
restrictive (to improve the scope of testing).

There are essentially two possible implementations for Setuid/Setgid on
Linux, either using SYS_SETUID32/SYS_SETGID32 or SYS_SETUID/SYS_SETGID,
depending on the architecture (see golang/go#1435 for why Setuid/Setgid
aren currently implemented for Linux neither in syscall nor in
golang.org/x/sys/unix).
Reduce duplication by merging the currently implemented variants and
adjusting the build tags accordingly.

This commit ensures we write the expected freezer cgroup state after
every state check, in case the state check does not give the expected
result. This can happen when a new task is created and prevents the
whole cgroup to be FROZEN, leaving the state into FREEZING instead.
This patch prevents the case of an infinite loop to happen.
