Let The Good Life able to play its intro video, the game creates a source reader from a `http://localhost:6000/<random-hash>` URL. This should also probably work with other games playing streams over http(s).
This is a very basic implementation, using urlmon, and it will download the entire stream to a local temporary file before playback. An more optimized implementation would probably use WinHttp and range requests to partially download the requested stream segments, but this can be implemented in a future change.
-- v6: mf/scheme_handler: Implement http(s):// scheme handler using urlmon. mf/scheme_handler: Split file scheme handler to scheme_handler.c. mf/tests: Add some network scheme resolver tests. include: Add MF_BYTESTREAM_EFFECTIVE_URL GUID declaration.
