Subject: add 'yocto-layer-example'

This is a first attemp to create a new slideset for day2 of yocto-trainig.

The slideset is based on 'yocto-advanced' but with integration of
'meta-schulung' explanations.

I used a slightly modified version of 'meta-schulung'. The following changes
are currently not available in git:

I don't use linux-yocto in meta-schulung, but use an own kernel-recipe and
integrate the RT-PREEMPT patch.

wic: i can't see the need for the second partition and the need for huge files
in the kconfig. It works for me by adding ' --align 1024 ' to the wic setup.
I decided to use ext2 instead of ext4.

I renamed the rootfs.bb file into schulung-base.bb

I use the u-boot recipe from poky. However i don't use u-boot for anything atm.
  But bootloader is on our agenda..
