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.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.

1.clock_systime_timespec(core function) always exist regardless the setting
2.CLOCK_MONOTONIC is a foundamental clock type required by many places

State of problem:
- Some drivers that do not support write operations (does not
have write handler or ioctl do not perform any write actions)
are registered with write permissions
- Some drivers that do not support read operation (does not
have read handler or ioctl do not perform any read actions)
are registered with read permissions
- Some drivers are registered with execute permissions
Solution:
- Iterate code where register_driver() is used and change 'mode'
parameter to reflect the actual read/write operations executed
by a driver
- Remove execute permissions from 'mode' parameter

Some PPG devices have 4 ADCs to output quad-channel PPG values while some of them only have 2 ADCs to output dual-channel PPG.
To deal the case above, the type PPGD(PPG of Dual-channel) takes the place of former type PPG, which also have 2-channel PPG outputs. Type PPGQ (PPG of Quad-channel) is new for 4-ADC-PPG. Both types have contained new data "gain" to indicate ADC gains of each PPG channel, for the reason that the gains may vary during automatical optical adjustments.

- "op_mode" instead of "mode" (compilation error)
- CONFIG_ISL29023_I2C_FREQUENCY instead of CONFIG_LM75_I2C_FREQUENCY
(probably a leftover)
- Fix a couple of format warnings: now using PRIu32
- Also minor comment changes

There were some mistakes in porting to the common sensors, and they
caused the following problems.
- Hardfault by bmp280_set_interval
- Read data always zero
drivers/sensors/hyt271.c:
* struct hyt271_dev_s: Identifier "lock_measure_cylce" was
misspelled. Fix to "lock_measure_cycle" and update all instances
in the file.
* hyt271_mr(), hyt271_cmd(), hyt271_change_addr(),
hyt271_measure_read(), hyt271_thread(): Update instances of the
renamed "lock_measure_cycle" variable and fix various typos in
comments.
1.fix crash casued by closing the handle during the reading.
2.fix set_interval fail sometime:When fakesensor was activated, csv file is not opened timely, so
the sensor->interval that set_interval() seted will be coverd by
interval form csv file.

This adds a sensor driver for the hyt271, hyt221, and hyt939 sensor module from
vendor iST (Innovative Sensor Technology). This sensor type is connected via i2c
bus and allows the measurement of relative humidity and temperature.
Each driver instance supports two different character device for each type
(/dev/sensor/tempX and /dev/sensor/humiX).
This driver also supports changing the i2c address of one connected sensor on
the bus. This requires a callback to the platform-specific board logic which
must ensure a power-on reset.
Optional the driver allows setting up a read interval for fetching sensor data.
This is done by a worker thread and can be useful when watching several sensors
via poll() by the userspace application.
