- GAP: allow to disable link supervision timeout
- HFP HF: only emit single event for RING and AG Status updates
- HFP AG: fix audio connection setup for in-band ringtone on incoming connection
- HFP: fix audio connection setup by HF if codec negotiation is supported
### Changed
- HCI: config I2S for BCM Controllers if `ENABLE_SCO_OVER_PCM`, reduce bit clock to 256/512 kHz

- HSP AG: emit HSP_SUBEVENT_BUTTON_PRESSED instead of audio connection setup/release
- Examples: use `btstack_event.h` getters instead of direct array access, use enum to compare status codes
- HFP: provide acl_handle in events to identify connection

- HCI Transport: extract convenience function declaration for h4, h5, em9304_spi, and usb into separate hci_transport_{type}.h
- GATT Client: Use ATT_READ_REQUEST for first blob of Read Long Characteristic and Read Long Characteristic Descriptor
- HID: Move `src/classic/hid.h` into `src` and prefix with `btstack_` to use it with BLE and avoid name clashes
