On socket creation respect the SELinuxContext= setting of the associated
service, such that the initial created socket has the same label as the
future process accepting the connection (since w.r.t SELinux sockets
normally have the same label as the owning process).

In most cases we refernced the concept as "initrd". Let's convert most
remaining uses of "initramfs" to "initrd" too, to stay internally
consistent.
This leaves "initramfs" only where it's relevant to explain historical
concepts or where "initramfs" is part of the API (i.e. in
/run/initramfs).

If a root hash is specified, we should be checking that it matches
the root hash in the verity signature partition, so let's not skip
processing of the verity signature partitions if a root hash is
specified.
We need explicit support to generate read-only filesystems, since we
always need to pass a source tree to the mkfs binary to populate the
filesystem. As such, let's add an explicit check to return a
recognizable error when users try to generate a read-only filesystem
that we don't support.
With this, I can now easily do:
systemd-nspawn --load-credential=ssh.authorized_keys.root:/home/lennart/.ssh/authorized_keys --image=… --boot
To boot into an image with my SSH key copied in. Yay!
let's make things a bit less racy: whenever we create an inode,
immediately open it via O_PATH, compare type and continue operations
with the acquired fd.
