1.Allow multi users to access the same sensor device simultaneously.
2.Get real state of sensor device by cmd SNIOC_GET_STATE for users.
3.Get update state since last read by poll without timeout for users.
4.Sensor device will be activated when first user open and will close when
last user closed.
5.When multi users to access device, driver always set the minimum
sampling interval and latency to the sensor device and allow
downsampled for users above the minimum sampling interval.
6.The circbuffer will overwrite old data when buffer is full, so if users
don't read data soon, data will be lost, and the oldest data in circbuffer
are returned to the users.
7.Always read the last data in the circbuffer as initial value for new
users when the sensor device has not yet generated new data.
8.when user uses poll, if subscription interval is satisfied, the POLLIN
events is returned for each users.
9.When new user generate or the state of sensor device changed, the POLLPRI
will notify to all users.
10.Support multi advertisers to subscribe their own data as loop test.

1.cmd:SNIOC_REGISTER with struct sensor_reginfo_s to register user sensor
2.cmd:SNIOC_UNREGISTER to unregister user sensor

1.Simplify buffer opeations to avoid frequent resize for batch and no-batch mode.
2.When sensor event is first generated, the buffer is initialized.
3.Remove and merge batch_number to buffer_number when device support batch mode.
