So... this breaks Smarts ABI, rebuild everything after updating Evas.

So... this breaks Smarts ABI, rebuild everything after updating Evas.

This patch adds some stuff for smart callback description/instropection, which
is still untested but doesn't break anything that's out there now. Should help
with bindings later on.

Also some parenting guidelines for smart objects, so it's easier to spawn a
subclass out of another. Look at Box and Table for an example on this.

And again, rebuild everything that uses smart objects after this update, or
the world will turn into a happy place where lawyers are no longer needed...
and we don't want to upset the lawyers.
