Macros
#define	SPA_CALLBACK_VERSION_MIN(c, v)
	Check if a callback c is of at least version v.
#define	SPA_CALLBACK_CHECK(c, m, v)
	Check if a callback c has method m of version v.
#define	SPA_CALLBACKS_INIT(_funcs, _data)
	Initialize the set of functions funcs as a spa_callbacks, together with _data.
#define	SPA_INTERFACE_INIT(_type, _version, _funcs, _data)
	Initialize a spa_interface.
#define	spa_callbacks_call(callbacks, type, method, vers, ...)
	Invoke method named method in the callbacks.
#define	spa_callbacks_call_fast(callbacks, type, method, vers, ...)
#define	spa_callback_version_min(callbacks, type, vers)
	True if the callbacks are of version vers, false otherwise.
#define	spa_callback_check(callbacks, type, method, vers)
	True if the callbacks contains method of version vers, false otherwise.
#define	spa_callbacks_call_res(callbacks, type, res, method, vers, ...)
	Invoke method named method in the callbacks.
#define	spa_callbacks_call_fast_res(callbacks, type, res, method, vers, ...)
#define	spa_interface_callback_version_min(iface, method_type, vers)
	True if the iface's callbacks are of version vers, false otherwise.
#define	spa_interface_callback_check(iface, method_type, method, vers)
	True if the iface's callback method is of version vers and exists, false otherwise.
#define	spa_interface_call(iface, method_type, method, vers, ...)
	Invoke method named method in the callbacks on the given interface object.
#define	spa_interface_call_fast(iface, method_type, method, vers, ...)
#define	spa_interface_call_res(iface, method_type, res, method, vers, ...)
	Invoke method named method in the callbacks on the given interface object.

#define	spa_hook_list_call_simple(l, type, method, vers, ...)
#define	spa_hook_list_do_call(l, start, type, method, vers, once, ...)
	Call all hooks in a list, starting from the given one and optionally stopping after calling the first non-NULL function, returns the number of methods called.
#define	spa_hook_list_call(l, t, m, v, ...)
	Call the method named m for each element in list l.
#define	spa_hook_list_call_once(l, t, m, v, ...)
	Call the method named m for each element in list l, stopping after the first invocation.
#define	spa_hook_list_call_start(l, s, t, m, v, ...)
#define	spa_hook_list_call_once_start(l, s, t, m, v, ...)
