generating input events

[mkemlogic]

Currently it is possible to play back recorded events with umockdev_testbed_load_evemu_events(). It would be very useful to be able to generate input events directly from the code, similar to umockdev_testbed_uevent(). Maybe there is a way I'm not aware of?

I have tried:

cmd = g_strdup_printf("evemu-event --sync /dev/input/event1 --type EV_SW --code 15 --value 1");
g_assert(g_spawn_command_line_async(cmd, NULL));

but the events are nowhere to be found. evtest does not pick them up when called like that:

cmd = g_strdup_printf("evtest /dev/input/event1");
g_assert(g_spawn_command_line_async(cmd, NULL));

Note that evtest run this way can see events submitted by umockdev_testbed_load_evemu_events().

I've made this PR mkemlogic#1 as a workaround. This allows me to generate one event at a time, or multiple if needed.
