Initial InputMappers for evdev input HAL.
The previous design of the InputHost wrapper classes made it very
painful to do testing, so this change also reverts to a more classical
C++ pattern for non-copyable objects. The InputHost classes still simply
call through to the input_host_t and callbacks as before.
Updated unittests to use gmock for mocking the InputHost interactions.
