HID: Introduce hidpp, a module to handle Logitech hid++ devices
Logitech devices use a vendor protocol to communicate various information with the device. This protocol is called HID++, and an exerpt can be found here: https://drive.google.com/folderview?id=0BxbRzx7vEV7eWmgwazJ3NUFfQ28&usp=shar The main difficulty which is related to this protocol is that it is a synchronous protocol using the input reports. So when we want to get some information from the device, we need to wait for a matching input report. This driver introduce this capabilities to be able to support the multitouch mode of the Logitech Wireless Touchpad T651 (the bluetooth one). The multitouch data is available directly from the mouse input reports, and we just need to query the device on connect about its caracteristics. HID++ and the touchpad features has a specific reporting mode which uses pure HID++ reports, but Logitech told us not to use it for this specific device. During QA, they detected that some bluetooth input reports where lost, and so the only supported mode is the pointer mode.
