Petri Gynther 054bfbcf4a input: Add userspace HID support
Enable HID protocol handling in userspace when UserspaceHID=true in input.conf.

Benefits of userspace HID:
1. Persistent HID/input pipeline
   For a Bluetooth HID device, the corresponding kernel HID/input devices are
   created only once when the Bluetooth HID device is used the first time.
   The HID/input pipeline is not destroyed and recreated every time when
   the Bluetooth HID device disconnects and reconnects.

2. HID vs HoG parity
   Enables HID and HoG devices to operate the same way in BlueZ stack, using
   uHID kernel module (/dev/uhid) to pass HID report data between bluetoothd
   and kernel HID subsystem.

3. Debugging
   It is easier to debug HID protocol in userspace than in HIDP kernel module.
