documentation/kerenl-manual: New directory and files for kernel manual.
This is the first draft of the Yocto Project Kernel manual. The
manual consists of two sections: concepts and a practical section that
has examples. It is based of Bruce Ashfield's kernel theory paper.
This first draft has been re-written and organized through the
concepts section. The remainder was just placed in as-is due to
time constraints for getting some kernel documentation up on the website.
The manual still needs scrubbing and organization in the latter half.
