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.

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.

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.

This moves the platform specific stuff in a separate package and keeps
the `volume` package and the defined interfaces light to import.
