[This is a manual port of commit dbd990d555 to release-1.1
branch. Original description follows.]
Remove intelrtd.Manager interface, since we only have a single
implementation, and do not expect another one.
Rename intelRdtManager to Manager, and modify its users accordingly.
Remove NewIntelRdtManager from factory.
Remove IntelRdtfs. Instead, make intelrdt.NewManager return nil if the
feature is not available.
Remove TestFactoryNewIntelRdt as it is now identical to TestFactoryNew.
Add internal function newManager to be used for tests (to make sure
some testing is done even when the feature is not available in
kernel/hardware).

TestGetContainerStats test a function that is smaller than the test
itself, and only calls a couple of other functions (which are
represented by mocks). It does not make sense to have it.
mockIntelRdtManager is only needed for TestGetContainerStats
and TestGetContainerState, which basically tests that Path
is called. Also, it does not make much sense to have it.

For the Nth time I wanted to replace parsing mountinfo with
statfs and the check for superblock magic, but it is not possible
since some code relies of mount options check which can only
be obtained via mountinfo.

In a (quite common) case RDT is not supported by the kernel/hardware,
it does not make sense to parse /proc/cpuinfo and /proc/self/mountinfo,
and yet the current code does it (on every runc exec, for example).
Fortunately, there is a quick way to check whether RDT is available --
if so, kernel creates /sys/fs/resctrl directory. Check its existence,
and skip all the other initialization if it's not present.

This test was written back in the day when findIntelRdtMountpointDir
was using its own mountinfo parser. Commit f1c1fdf911 changed that,
and thus this test is actually testing moby/sys/mountinfo parser, which
does not make much sense.
Remove the test, and drop the io.Reader argument since we no longer need
to parse a custom file.

In case resctrl filesystem can not be found in /proc/self/mountinfo
(which is pretty common on non-server or non-x86 hardware), subsequent
calls to Root() will result in parsing it again and again.
Use sync.Once to avoid it. Make unit tests call it so that Root() won't
actually parse mountinfo in tests.

This aligns v2 usage calculations more closely with v1.
Current node-level reporting for v1 vs v2 on the same
machine under similar load may differ by ~250-750Mi.
Also return usage as combined swap + memory usage, aligned
with v1 and non-root v2 cgroups.
`mem_cgroup_usage` in the kernel counts NR_FILE_PAGES
+ NR_ANON_MAPPED + `nr_swap_pages` (if swap enabled) [^0].
Using total - free results in higher "usage" numbers.
This is likely due to various types of reclaimable
memory technically counted as in use (e.g. inactive anon).

Since commit e3cf217cf1 actions/setup-go@v4 uses caching
implicitly, and olangci/golangci-lint-action also uses caching.
These two caches clash, resulting in multiple warnings in CI logs.
The official golangci-lint-action solution is to disable caching
for setup-go job (see [1]). Do the same.

For "make integration", the tests are run inside a Docker/Podman
container. Problem is, if cgroup v2 is used, the in-container
/sys/fs/cgroup/cgroup.subtree_control is empty.
The added script, used as Docker entrypoint, moves the current process
into a sub-cgroup, and then adds all controllers in top-level
cgroup.subtree_control.

[XXX 1.1 note: the above subject and the rest of the commit message
is the original description from the cherry-picked commit which talks
about 1.19 -- while in fact it is now 1.20.]
This variable is used in curl to download a go release, so we are using
the initial Go 1.19 release in Cirrus CI, not the latest Go 1.19.x
release.
From the CI perspective, it makes more sense to use the latest release.
Add some jq magic to extract the latest minor release information
from the download page, and use it.
This brings Cirrus CI jobs logic in line with all the others (GHA,
Dockerfile), where by 1.20 we actually mean "latest 1.20.x".

runc delete is supposed to remove all the container's artefacts.
In case systemd cgroup driver is used, and the systemd unit has failed
(e.g. oom-killed), systemd won't remove the unit (that is, unless the
"CollectMode: inactive-or-failed" property is set).
Call reset-failed from manager.Destroy so the failed unit will be
removed during "runc delete".

In code we have frozen the cgroup to avoid the processes get
an occasional "permission denied" error, while the systemd's application of device
rules is done disruptively. When the processes in the container can not
be frozen over 2 seconds (which defined in fs/freezer.go),
we still update the cgroup which resulting the container get an occasional
"permission denied" error in some cases.
Return error directly without updating cgroup, when freeze fails.

It doesn't matter whether static or dynamic linking is used, runc
always needs libcontainer/nsenter, which is written in C and thus
requires cgo. Same is true for libcontainer/integration.
In addition, contrib/pkg/seccompagent also needs cgo (if seccomp build
tag is set), as it need to be linked against libseccomp C library.
By default, cgo is disabled when cross-compiling, meaning that
CGO_ENABLED=1 has to be set explicitly in such cases.
In all other cases (e.g. other contrib binaries) we do not need cgo.
Remove CGO_ENABLED=1 from GO_BUILD_STATIC (as it does not have anything
to do with static linking), and add it to all targets that require it.

1. Set to empty value by default.
2. Assume Linux (remove GOOS check, since we do not support other OSes).
3. Instead of using a "not-supported" list, use a "supported" list
(as Go release notes usually say which platforms are supported).
As of today, -buildmode=pie is supported for:
* linux/386, linux/amd64, linux/arm, linux/arm64, and linux/ppc64le
(since Go 1.6, see https://tip.golang.org/doc/go1.6#compiler)
* linux/s390x (since Go 1.7, which adds the initial port)
* linux/riscv64 (since Go 1.16, see
https://tip.golang.org/doc/go1.16#riscv)
NOTE this does not mean we support these architectures; it is merely
a way to see if -buildmode=pie can be used.
