75be860f34 overlayfs: Allow not used mount points
When machine configuration defines a mount point, which is not used in
any recipe, allow to fall through and only report a note in the logs.
This can be expected behavior, when a mount point is defined for several
machines, but not used in all of them

0af576a3b0 overlayfs: add docs about skipping QA check & service dependencies
Add some documentation about skipping the QA check related to missing
fstab entries or mount units for base mount points where the overlayfs
is mounted from.

Also add a short paragraph about adding a systemd unit dependency to
services in recipes, so that they are started only after the overlayfs
is mounted and ready.

No functional change.

9633ecebb9 overlayfs: add systemd unit path prefix to FILES:${PN} array
The 'FILES:${PN}' array is missing the systemd unit dir prefix causing
them to not be packaged and the build fails with the
`installed-vs-shipped` error.

This adds the `systemd_system_unitdir` variable in front of every unit
file added with this class.

9c8ea9dcf1 overlayfs: all overlays unit
Application can depend on several overlayfs mount points. Provide a
systemd unit application can depend on to make sure all overlays are
mounted before it is started to avoid any race conditions

d6e1f08ee3 overlayfs.bbclass: generate overlayfs mount units
It's often desired in Embedded System design to have a read-only rootfs.
But a lot of different applications might want to have a read-write access
to some parts of a filesystem. It can be especially useful when your update
mechanism overwrites the whole rootfs, but you want your application data
to be preserved between updates. This class provides a way to achieve that
by means of overlayfs and at the same time keeping the base rootfs read-only.
