The new configuration file was initially generated by golangci-lint
migrate, when tweaked to minimize and simplify.
golangci-lint v2 switches to a new version of staticcheck which shows
much more warnings. Some of them were fixed by a few previous commits,
and the rest of them are disabled.
In particular, ST1005 had to be disabled (an attempt to fix it was made
in https://github.com/opencontainers/runc/pull/3857 but it wasn't
merged).
Also, golangci-extra was modified to include ALL staticcheck linters.

There is an announce that Ubuntu 20.04 will be removed in April,
and in March there will be a few "brown-out" dates/times when
it won't work.
This leaves us with no other options than to remove ubuntu-20.04
from the testing matrix.
As a result, cgroup v1 testing will only be done on AlmaLinux 8
running on CirrusCI. It is probably going to be sufficient for
the time being (until we deprecate cgroup v1).
If not, our options are
- run Ubuntu 20.04 (or other cgroup v1 distro) in a VM on GHA;
- switch to cirrus-ci.

This allows to make a 17% smaller runc binary by not compiling in
checkpoint/restore support.
It turns out that google.golang.org/protobuf package, used by go-criu,
is quite big, and go linker can't drop unused stuff if reflection is
used anywhere in the code.
Currently there's no alternative to using protobuf in go-criu, and since
not all users use c/r, let's provide them an option for a smaller
binary.
For the reference, here's top10 biggest vendored packages, as reported
by gsa[1]:
$ gsa runc | grep vendor | head
│ 8.59% │ google.golang.org/protobuf │ 1.3 MB │ vendor │
│ 5.76% │ github.com/opencontainers/runc │ 865 kB │ vendor │
│ 4.05% │ github.com/cilium/ebpf │ 608 kB │ vendor │
│ 2.86% │ github.com/godbus/dbus/v5 │ 429 kB │ vendor │
│ 1.25% │ github.com/urfave/cli │ 188 kB │ vendor │
│ 0.90% │ github.com/vishvananda/netlink │ 135 kB │ vendor │
│ 0.59% │ github.com/sirupsen/logrus │ 89 kB │ vendor │
│ 0.56% │ github.com/checkpoint-restore/go-criu/v6 │ 84 kB │ vendor │
│ 0.51% │ golang.org/x/sys │ 76 kB │ vendor │
│ 0.47% │ github.com/seccomp/libseccomp-golang │ 71 kB │ vendor │
And here is a total binary size saving when `runc_nocriu` is used.
For non-stripped binaries:
$ gsa runc-cr runc-nocr | tail -3
│ -17.04% │ runc-cr │ 15 MB │ 12 MB │ -2.6 MB │
│ │ runc-nocr │ │ │ │
└─────────┴──────────────────────────────────────────┴──────────┴──────────┴─────────┘
And for stripped binaries:
│ -17.01% │ runc-cr-stripped │ 11 MB │ 8.8 MB │ -1.8 MB │
│ │ runc-nocr-stripped │ │ │ │
└─────────┴──────────────────────────────────────────┴──────────┴──────────┴─────────┘

The idea is to remove the need for cloning the entire runc binary by
replacing the final execve() call of the container process with an
execve() call to a clone of a small C binary which just does an execve()
of its arguments.
This provides similar protection against CVE-2019-5736 but without
requiring a >10MB binary copy for each "runc init". When compiled with
musl, runc-dmz is 13kB (though unfortunately with glibc, it is 1.1MB
which is still quite large).
It should be noted that there is still a window where the container
processes could get access to the host runc binary, but because we set
ourselves as non-dumpable the container would need CAP_SYS_PTRACE (which
is not enabled by default in Docker) in order to get around the
proc_fd_access_allowed() checks. In addition, since Linux 4.10[1] the
kernel blocks access entirely for user namespaced containers in this
scenario. For those cases we cannot use runc-dmz, but most containers
won't have this issue.
This new runc-dmz binary can be opted out of at compile time by setting
the "runc_nodmz" buildtag, and at runtime by setting the RUNC_DMZ=legacy
environment variable. In both cases, runc will fall back to the classic
/proc/self/exe-based cloning trick. If /proc/self/exe is already a
sealed memfd (namely if the user is using contrib/cmd/memfd-bind to
create a persistent sealed memfd for runc), neither runc-dmz nor
/proc/self/exe cloning will be used because they are not necessary.

The default timeout is 360 minutes, which is way long for these jobs.
If the CI (or a test) has stuck, we'd better know about it earlier than
in 6 hours.
Set the timeouts for some [relatively] long running jobs conservatively:
- test and release jobs usually take ~10 minutes;
- lint job takes 1 minute (but can be a few times slower when we switch
Go or golangci-lint version);
- cross-386 job takes about 2 minutes;
- the rest is seconds (and I am lazy to set timeouts everywhere).
