This follows the class types description of yocto [1] and is aligned to
its own layout where we have similar classes. One deviation from yocto
is patch.bbclass which we inherit explicitly from dpkg-base.

As there was no feedback on [1], I interpreted it as an OK. So here
comes a full refactoring of our classes folders according to [2] and a
conversion of all recipe helper includes into classes (majority of the
changes).

There are some extra changes to the barebox include/class, but my
impression is that this one is still broken, lacking the machine in its
target name, just like u-boot and other machine-specific packages have.
But I don't have any barebox cases around and lack insights into how it
is build, so I didn't go into details here.

Jan

PS: Patch stats are misleading. This is copying things around and then
changing the original files to stubs. It is not eliminating code, is is
actually adding a bit as long as we carry the transitional stubs.

This follows the class types description of yocto [1]. The only class
remaining in the classes dir is terminal.bbclass, just like in yocto.

+The following includes were considered internal and are no longer available:
+
+ - `recipes-bsp/optee-os/optee-os.inc`
+ - `recipes-support/container-loader/container-loader.inc`
+
+The other original includes still exist and inherit the corresponding new
+class. However, they issue a warning to perform the recommended conversion
+because these transitional includes will eventually be dropped.
