These were all marked deprecated in commit a75076b4a4 ("Switch to
opencontainers/cgroups") when we switched maintenance of our cgroup code
to opencontainers/cgroups.
Users have had ample time to switch to opencontainers/cgroups
themselves, so we can finally remove this.
Note that the whole libcontainer/devices package will be moved to
moby/sys in the near future, so this whole package will be marked
deprecated soon.

Currently, libcontainer/devices contains two things:
1. Device-related configuration data structures and accompanying
methods. Those are used by runc itself, mostly by libct/cgroups.
2. A few functions (HostDevices, DeviceFromPath, GetDevices).
Those are not used by runc directly, but have some external users
(cri-o, microsoft/hcsshim), and they also have a few forks
(containerd/pkg/oci, podman/pkg/util).
This commit moves (1) to a new separate package, config (under
libcontainer/cgroups/devices), adding a backward-compatible aliases
(marked as deprecated so we will be able to remove those later).
Alas it's not possible to move this to libcontainer/cgroups directly
because some IDs (Type, Rule, Permissions) are too generic, and renaming
them (to DeviceType, DeviceRule, DevicePermissions) will break backward
compatibility (mostly due to Rule being embedded into Device).

Go 1.17 introduce this new (and better) way to specify build tags.
For more info, see https://golang.org/design/draft-gobuild.
As a way to seamlessly switch from old to new build tags, gofmt (and
gopls) from go 1.17 adds the new tags along with the old ones.
Later, when go < 1.17 is no longer supported, the old build tags
can be removed.
Now, as I started to use latest gopls (v0.7.1), it adds these tags
while I edit. Rather than to randomly add new build tags, I guess
it is better to do it once for all files.
Mind that previous commits removed some tags that were useless,
so this one only touches packages that can at least be built
on non-linux.

Do this for all errors except one from unix.*.
This fixes a bunch of errorlint warnings, like these
libcontainer/generic_error.go:25:15: type assertion on error will fail on wrapped errors. Use errors.As to check for specific errors (errorlint)
if le, ok := err.(Error); ok {

gofumpt (mvdan.cc/gofumpt) is a fork of gofmt with stricter rules.
Brought to you by
git ls-files \*.go | grep -v ^vendor/ | xargs gofumpt -s -w
Looking at the diff, all these changes make sense.
Also, replace gofmt with gofumpt in golangci.yml.

Move the Device-related types to libcontainer/devices, so that
the package can be used in isolation. Aliases have been created
in libcontainer/configs for backward compatibility.
