To actually use requests with the m2m device, requests need to be allocated on the underlying media device. This can only be done if the media device is opened which means acquiring it. Add a function to check if the m2m device supports requests by acquiring the media device, asking it and then releasing it again. Also add a function to allocate requests that acquires the internal media device and releases it after allocating the requests.
