This is as close to usptream as currently possibly. Only a few changes were done to the dependencies: the wasm target was removed and the coremidi dependency was updated to pick up a more recent version so that we don't need to vendor separate versions of the core-foundation and core-foundation-sys crates. This vendors the following crates: * alsa-sys * alsa * coremidi * coremidi-sys * memalloc * midir Overall this adds ~30K lines of code, over half of which is in the alsa bindings alone.
