Multifilesink messages and unclear doc

[Thibault Saunier]

Him

Those fields are inside the GstStructure that you can get from the message
using: gst_message_get_structure[0]. Hotodoc[1] is somehow reporting wrong
types for those fields in the python doc, something to fix there (please
report a bug)
