There are requirements regarding source input device identification from input events
especially in Tizen. Evas input event callbacks are being used in applications and
ecore input events are being used by applications and some toolkits such as DALi, Volt,
Webkit and so on.
From the input device identification point of view, there is Evas_Device in evas common
and it can be useful to set/get the source device information associated with each evas input
event. However, in ecore input, there is no data structures and events which can be used
for helping input device identification with ecore input events.
Thus, I added Ecore_Device data structure and some events which can be used to store the source
device information to the ecore events.
