Use layout_compare() for AudioLayout.__eq__()

And use AVCodecContext.frame_num instead of keeping track ourselves.

@WyattBlue Hi! How can this be part of a patch release if it changes the public api by removing encoded_frame_count? My code is relying on that. How could I replace it? It would be nice if the docs could contain a note about this and how to adjust to it.

If some property is not exercised in the test suite, it's not part of the public api. This api wasn't documented either, it was just internal plumbing that was made read-only instead of private for some reason.

If your code does rely on this, just use v16.1.0. Consider this change a post release for v17.

@WyattBlue Thank you for your response. I assumed it was public since it was documented here https://pyav.basswood-io.com/docs/16.1/api/video.html#av.video.codeccontext.VideoCodecContext.encoded_frame_count
