Add a new signal for formatting the filename, which receives a GstSample containing the first buffer from the reference stream that will be muxed into that file. Useful for creating filenames that are based on the running time or other attributes of the buffer. To make it work, opening of files and setting filenames is now deferred until there is some data to write to it, which also requires some changes to how async state changes and gap events are handled.
