Audio no longer needs to be the same format/sample rate to play correctly. This
should be the last step to making audio work correctly (minus several
optimizations still yet to be done).

It became increasingly clear that video and audio retrieval require different

began audio conform code in ffmpegdecoder
...
For accuracy, whenever we need to perform an audio resample, we need to do it
in advance. This is in a process called "conforming" and this commit introduces
the framework by which the decoder can automatically conform an audio stream
to arbitrary parameters for accurate rendering.

Not all media starts with a timecode of 0 and the Decoder class needs to
handle such a situation. This commit corrects that.

reimplement Q_DISABLE_COPY_MOVE for full compatibility with versions < 5.13

I was under the impression Q_DISABLE_COPY_MOVE was a much older function than
it is. Since we historically target 5.6 and these functions are small
convenience functions, I just implemented them in the actual codebase.

miscellaneous other changes to make audio rendering work

Many changes were made throughout the codebase to support audio, these are
most of the small changes necessary.
The audio support still is not perfect. I still need to write in resampling
support. After that it should work correctly with all audio types.

more coherent render threading for now

Once again, conceptually this system should work, however it does not seem to
be the most efficient and it wouldn't surprise me if the multithreading was
eventually upgraded to an even more coherent system one day. However for
"core principles" this should be fairly decent.
