migrate to github.com/containerd/log v0.1.0
The github.com/containerd/containerd/log package was moved to a separate
module, which will also be used by upcoming (patch) releases of containerd.

This patch moves our own uses of the package to use the new module.

test/volume: Replace Check with NilError where suitable
In these cases, continuing after a non nil error will result in a nil

volume: remove the short RRO forms in favor of the long forms
"ro-non-recursive", "ro-force-recursive", and "rro" are
now removed from the legacy mount API.

CLI may still support them via the new mount API (if we want).

647c2a6cdd Restore active mount counts on live-restore
When live-restoring a container the volume driver needs be notified that
there is an active mount for the volume.
Before this change the count is zero until the container stops and the
uint64 overflows pretty much making it so the volume can never be
removed until another daemon restart.

Support recursively read-only (RRO) mounts
`docker run -v /foo:/foo:ro` is now recursively read-only on kernel >= 5.12.

Automatically falls back to the legacy non-recursively read-only mount mode on kernel < 5.12.

Use `ro-non-recursive` to disable RRO.
Use `ro-force-recursive` or `rro` to explicitly enable RRO. (Fails on kernel < 5.12)

SELinux: fix ENOTSUP errors not being detected when relabeling
Commit 12c7541f1f updated the
opencontainers/selinux dependency to v1.3.1, which had a breaking
change in the errors that were returned.

Before v1.3.1, the "raw" `syscall.ENOTSUP` was returned if the
underlying filesystem did not support xattrs, but later versions
wrapped the error, which caused our detection to fail.

This patch uses `errors.Is()` to check for the underlying error.
This requires github.com/pkg/errors v0.9.1 or above (older versions
could use `errors.Cause()`, but are not compatible with "native"
wrapping of errors in Go 1.13 and up, and could potentially cause
these errors to not being detected again.

Tweak bind mount errors
These messages were enhanced to include the path that was
missing (in df6af282b9), but
also changed the first part of the message.

This change complicates running e2e tests with mixed versions
of the engine.

Looking at the full error message, "mount" is a bit redundant
as well, because the error message already indicates this is
about a "mount";

    docker run --rm --mount type=bind,source=/no-such-thing,target=/foo busybox
    docker: Error response from daemon: invalid mount config for type "bind": bind mount source path does not exist: /no-such-thing.

Removing the "mount" part from the error message, because
it was redundant, and makes cross-version testing easier :)

763d839261 Add ADD/COPY --chown flag support to Windows
This implements chown support on Windows. Built-in accounts as well
as accounts included in the SAM database of the container are supported.

NOTE: IDPair is now named Identity and IDMappings is now named
IdentityMapping.

The following are valid examples:
ADD --chown=Guest . <some directory>
COPY --chown=Administrator . <some directory>
COPY --chown=Guests . <some directory>
COPY --chown=ContainerUser . <some directory>

On Windows an owner is only granted the permission to read the security
descriptor and read/write the discretionary access control list. This
fix also grants read/write and execute permissions to the owner.

1caeb79963 Fix bindmount autocreate race
When using the mounts API, bind mounts are not supposed to be
automatically created.

Before this patch there is a race condition between valiating that a
bind path exists and then actually setting up the bind mount where the
bind path may exist during validation but was removed during mountpooint
setup.

This adds a field to the mountpoint struct to ensure that binds created
over the mounts API are not accidentally created.
