meta-emenlow: Layer for eMenlow-based systems.

This layer provides a kernel suitable for booting on eMenlow-based systems,
plus support for Poulsbo graphics.  The Poulsbo support includes a
kernel patch for the graphics driver, a couple of libraries, the 2D
and 3D X drivers, and a properly configured X server.

The closed portions of this support are in the 3D driver, xpsb-glx.
This package contains the binaries for the libraries that communicate
with the kernel driver and a mesa library which uses those libraries.

There is a README in meta-emenlow/ describing how to enable this layer.

Where possible, the recipes use bitbake's new .bbappend facility in
order to avoid copying recipes from meta/.

There are checksums and license information for all of the new packages.
