This patch doesn't do everything that is needed to have systemd-nspawn work.
But it does everything that is needed and which I have written in a clear and
uncontroversial way. I think it's best to get this upstream now and then
either have a separate discussion about the more difficult issues, or wait
until I devise a way of solving those problems that's not too hacky.
Who knows, maybe someone else will devise a brilliant solution to the remaining
issues after this is accepted upstream.
Also there's a tiny patch for systemd_machined_t that is required by
systemd_nspawn_t.

userdomains should not alter labels of kernel pseudo filesystems, but allowing setfiles/restorecon(d) to check the contexts helps spotting incorrect labels
This patch adds missing permissions in the kernel module that prevent
to run it without the unconfined module.
This second version improves the comment section of new interfaces:
"Domain" is replaced by "Domain allowed access".

Interface fs_register_binary_executable_type allow registering
interpreters using a filesystem monted on /proc/sys/fs/binfmt_misc. In
order to access this filesystem, the process needs to search every
parent directory of the mountpoint.

When reading or managing noxattr fs files or symbolic links, also
let the user list noxattr fs directories.
This patch should be applied after the following one:

"Let users read/manage symlinks on fs that do not support xattr"

Let unprivileged and administrative users read symbolic links on
filesystems that do not support extended attributes (xattr) such
as cdroms, FAT, NTFS and so on.

systemd creates a new network namespace for services which are using
PrivateNetwork=yes.
In the implementation, systemd uses a socketpair as a storage buffer for
the namespace reference file descriptor (c.f.
https://github.com/systemd/systemd/blob/v228/src/core/namespace.c#L660).
One end of this socketpair is locked (hence the need of "lock" access to
self:unix_dgram_socket for init_t) while systemd opens
/proc/self/ns/net, which lives in nsfs.
While at it, add filesystem_type attribute to nsfs_t.
Move cgroup_t declarations from kernel.te to filesystem.te
Redo cgroup interfaces in filesystem.if
Add file context specification for /cgroup mountpoint to filesystem.fc
