HID: magicmouse: enable Magic Trackpad support
The trackpad speaks a similar, but different, protocol from the magic mouse. However, only small code tweaks here and there are needed to make basic multitouch work. Extra logic is required for single-touch emulation of the touchpad. The changes made here take the approach that only one finger may emulate the single pointer when multiple fingers have touched the screen. Once that finger is raised, all touches must be raised before any further single touch events can be sent. Sometimes the magic trackpad sends two distinct touch reports as one big report. Simply splitting the packet in two and resending them through magicmouse_raw_event ensures they are handled properly. I also added myself to the copyright statement.
