I have a question about the details of GITransfer.

Consider a function accepting/returning a list of objects. Is this
right:

In argument (g_arg_info_get_ownership_transfer):

* GI_TRANSFER_NOTHING: caller owns list and objects
* GI_TRANSFER_CONTAINER: callee owns list, caller owns objects
   (quite weird case, what function calls do this?)
* GI_TRANSFER_EVERYTHING: callee owns list and object

In return value (g_callable_info_get_caller_owns):

* GI_TRANSFER_NOTHING: callee owns list and objects
* GI_TRANSFER_CONTAINER: caller owns list, callee owns objects
* GI_TRANSFER_EVERYTHING: caller owns list and object
