[PATCH wayland] Break resource creation into two functions.

Jason Ekstrand jason at jlekstrand.net
Fri Jun 28 11:32:06 PDT 2013


This commit changes the resource createion/setup API to be more like
wl_proxy.  Instead of having one master function that does everything
except setup the destructor it is broken into two more balanced functions.
First, the wl_client_add/new_versioned_object function sets up all of the
immutable bits such as the version and the interface.  Then
wl_resource_set_implementation is called to set up all of the mutable bits
such as implementation, user data, and destructor.  This more closely
matches client-side and (I think) makes more sense.
