[PATCH weston 2/3] compositor: pass the backend config struct to the backends init function

[Giulio Camuffo]

Add new configuration argument to the backend_init() function, which
will replace the current argc, argv, and config arguments.
After each backend is converted individually the unused parameters
will be removed.
