[oe] rename files dirs

[Frans Meulenbroeks]

Currently lots of our patches reside in a directory called files.
Somewhere in the past koen explained me that that is not really proper
(and I agree with them).
files should only be used in case a dir has multiple recipes (say X.bb
and Y.bb) which both use the same patch
If there is only a single recipe with multiple versions (e.g.X_0.bb
and X_1.bb) then common patches should go into a dir X.
And if the patches are for a specific version they should go in X-0, X-1 etc.

When I'm bored again on a rainy sunday afternoon or so, I can spent
some time on moving things.
Are people comfortable with that?
Also what would be the preferred way to store the patches for a recipe
with only one version (Z_3.bb)
Should this preferably be in Z or in Z-3 ?

Your opinion is apprecated
