runc in this file is actually a function that does `run runc ...`,
and `run` sets variable `$status` as the exit code, so `$status`
is what should be checked.
If calling runc directly (as in `__runc ...`), then $? is legit.
While at it, remove an obsoleted comment, and an unneeded
`ret=$?` assignment (check `$?` directly).

Run in the same environment as systemd tests.
Disable CRIU tests because:
- they all fail with cgroup v2;
- CRIU v3.14 is required and it's not yet released, and
rebuilding it from sources with patches applied (like
it is currently done in Dockerfile) is too much work.

Those needs to be run on the (Vagrant Fedora 31) host
(since we need real systemd running), and so we have
to have all the tools needed to compile runc and run
the tests.
The good news is Fedora packages a decent and recent release
of bats-core (1.1.0), which we can use (Debian does not),
and we can also use golang (currently 1.13.9) from Fedora.
The bad news are
1. Currently cgroups tests are only working with
RUNC_USE_SYSTEMD=yes (addressed by #2299, #2305)
2. Tests in events.bats do not work (need cgroupv2
memory.events support)
3. Fedora 31 image is 6 months old (and has broken
container-selinux policy) so we need `dnf update`,
which adds ~5 min to test time.
[v2: add -t to ssh to enforce pty]
[v3: disable events tests for cgroupv2]
[v4: update fedora packages, use a single dnf transation]

1. Add `cgroups_v1` and `cgroups_v2` options to `requires`.
2. Modify `check_cgroup_value` to be able to work with v2.
3. Split `test "update"` into two:
- (1) testing cgroupv1-only cpu shares and cfs
- (2) testing limits that are more or less common
between v1 and v2: memory/swap, pids, cpusets.

... and add kmem-tcp to cgroups kmem test.
First, we already have a separate kmem test in cgroups.bats.
Second, making kmem a requirement leads to skipping all the other
test cases in the update.bats test.
Third, kmem limit is being removed from the kernel, so it makes sense
to handle it separately.

1. Consolidate all the cgroup-related initialization code to
a single place, init_cgroup_paths(), so we can see which
variables are set.
2. Lazily call init_cgroup_paths() from all places that require it.
3. Don't set globals KMEM and RT_PERIOD.
4. Slightly clarlify variables naming:
- use OCI_CGROUPS_PATH for cgroupsPath in config.json
- use REL_CGROUPS_PATH for relative cgroups path
5. Do not hardcode the list of cgroup subsystems -- get it from
/proc/cgroup.
6. Preliminary support for cgroupv2 unified hierarchy (not yet working).

Consolidate two implementations of check_cgroup_value()
into one, putting it into helpers.
Remove the first parameter, deducing the variable to get
the path from by the parameter name.
This should help in future cgroupv2 support.

If container's config.json have `"terminal": true` setting in its
"process" section, runc exec assumes that stdin (fd 0) is a terminal
and tries to use it.
This leads to the following error in case stdin is not a terminal:
> ERRO[0000] exec failed: provided file is not a console
So, even if -t/--tty is not set, exec uses stdin as a terminal.
It does not help that urfave/cli v1 parser we use does not allow
to use `-t no` or `-t false`.
Since the settings in config.json is probably for the container run/start,
not for the auxiliary process started inside a container with exec, do
not use a setting from there, only treating stdin as a terminal in case
`-t` is explicitly given.
Tests that use runc exec with a terminal are amended with -t.

Currently, the id verification in integration test failed on arm
platform due to the inconsistent /etc/group in the busybox images
for arm and x86. To be specific, the nogroup id in x86 is 99 while
that in arm is 65534.
99 is old id for nogroup, and no longer be used in recent system,
so sync the busybox image for arm and x86 to the image in busybox
github. Also change the id verification rule in integration test.

This allows us to test runc using libcontainer's systemd driver, by
passing an extra `--systemd-cgroup` argument to the calls to runc.
Tested:
$ sudo make localintegration TESTPATH='/exec.bats' RUNC_USE_SYSTEMD=1
And confirmed that systemd was in use by looking at creation and removal
of libcontainer_<pid>_systemd_test_default.slice test slices. Also
introduced a breakage in systemd cgroup driver and confirmed that the
tests failed as expected.

Upstream renamed the feature check for lazy migration support from
'lazy_pages' to 'uffd'. The lazy migration test case was therefore
not running at all. This enables the lazy migration test case in runc
again.
The test will, however, not run in travis as the kernel is too old.
But it works again locally.

In some cases, /sys/fs/cgroups is mounted read-only. In rootless
containers we can consider this effectively identical to having cgroups
that we don't have write permission to -- because the user isn't
responsible for the read-only setup and cannot modify it. The rules are
identical to when /sys/fs/cgroups is not writable by the unprivileged
user.
An example of this is the default configuration of Docker, where cgroups
are mounted as read-only as a preventative security measure.
