[PATCH 0/4] MR7216: winebth.sys part 3: Introduce IOCTLs related to radio discoverability, connectability and device inquiry.

[Vibhav Pant (＠vibhavp)]

The Windows Bluetooth stack uses private IOCTLs in order to set the [discoverability](https://learn.microsoft.com/en-us/windows/win32/api/bluetoothapis/nf-bluetoo...) and [connectability](https://learn.microsoft.com/en-us/windows/win32/api/bluetoothapis/nf-bluetoo...) status of a local radio, and to start/stop the device inquiry procedure. This MR introduces 3 wine-specific IOCTL codes for the same purposes, as most applications seem to the Win32 API itself for these operations:

* IOCTL_WINBTH_RADIO_SET_FLAG
* IOCTL_WINEBTH_RADIO_START_DISCOVERY
* IOCTL_WINEBTH_RADIO_STOP_DISCOVERY
