Léo Lam 843b030eda WiimoteReal: Add a hidapi IO implementation
Based on ca0c2efe7a. Credits go to flacs.
However, unlike the original commit, hidapi does not completely replace
the current implementations, so we can still connect Wiimotes with 1+2
(without pairing).

Also, it is only used on Linux and OS X for now. This removes the
advantage of having only one implementation but there is no other
choice: using hidapi on Windows is currently impossible because
hid_write() is implemented in a way that won't work with Wiimotes.

Additionally:
* We now check for the device name in addition to the PID/VID so we can
  support the Balance Board and maybe third-party Wiimotes too. This
  doesn't achieve anything with the DolphinBar but it does with hidraw.
* Added a check to not connect to the same device more than once.
