[PATCH 0/6] MR6362: mfsrcsnk, mfmp4srcsnk: Register the sink ans source classes in the DLLs they belong to.

[Rémi Bernon (＠rbernon)]

This allows to use DLLOVERRIDES with native DLLs, making it more convenient for testing and debugging. This will also makes it possible to create an alternative media source implementation with a different backend without breaking the current one.
