Certain unnamed parties have grown to depend on internal API details of
ecore_wl2, despite it being labelled as beta api.
In an effort to promote peace and harmony we're surrendering the ecore_wl2
namespace to anyone that didn't notice it was beta api, and renaming
the library to something more obviously not stable.
This allows people dependent on ecore_wl2 unstable bits to create them
in a thin shim layer around the notstable library.
