Instead of having #ifdefs to hook into the normal EGL winsys, the KMS winsys now overrides any winsys functions that it wants. Where the winsys wants to hook into a point within a function provided by the EGL winsys there is a EGL-platform vtable which gets set on the EGL renderer data during renderer_connect. The KMS-specific data on all of the structures is now allocated separately by the KMS winsys and is pointed to by a new 'platform' pointer in the EGL data.
