[OE-core] oe-core cleanup...

[Mark Hatle]

I finally got a chance to look at the oe-core and where it currently is..  Some
suggestions below:

LICENSE file, this may need to be cleaned up to only cover the components
actually in the oe-core.

README likely needs some revision

README.hardware needs a lot of revision.  Anything outside of support for QEMU
should be removed.

The meta-demoapps and meta-rt components, will those be staying or going?

The meta/recipes.txt needs to be verified as still what we want -- I assume it
is at this point..

meta/recipes-...  sato, qt, gnome, I thought were going elsewhere?

Do the items in the "scripts" need to be renamed or is Poky being kept in the
naming?  Same with the poky-init-build-env?

Then I also assume the items in the documentation directory need to be cleaned
up as well...

Let me know what you'd like me to try and tackle -- or if we need to bring these
items up at the TSC for recommendation.
