Some device include a temperature sensor, usually used as a
companion for helping in drift compensation, that measure the
die temperature. This temperature IS NOT related to the the
ambient temperature, hence a clean separation between the two
is required.
This commit introduces a clean separation between the two
types of temperature leaving the old deprecated definition
still there.
The list of current drivers that read the die (and not the ambient)
temperature is the following:
- adxl362
- bma280
- bmg160
- bmi160
- fxos8700
- lis3mdl
- lsm6ds0
- lsm6dsl
- lsm9ds0
- mpu6050

Based on the discussion in #5693, the reason why humidity was defined
in milli-percent was likely following Linux which defines it as such
in its sensor subsystem:
http://elixir.free-electrons.com/linux/latest/source/Documentation/ABI/testing/sysfs-bus-iio#L263
However, Linux defines temperature in milli-degrees either, but
Zephyr uses degrees (similarly for most other quantities). Typical
sensor resolution/precision for humidity is also on the order of 1%.
One of the existing drivers, th02.c, already returned values in
percents, and few apps showed it without conversion and/or units,
leading to confusing output to user like "54500".
So, switching units to percents, and update all the drivers and
sample apps.
For few drivers, there was also optimized conversion arithmetics
to avoid u64_t operations. (There're probably more places to
optimize it, and temperature conversion could use such optimization
too, but that's left for another patch.)

Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99

This reverts commit e60af3be66.
We revert this as we intent to move away from {u}int{8,16,32,64}_t types
to our own internal types for sized variables so we shouldn't need the
PRI macros anymore.

To allow for various libc implementations (like newlib) in which the way
various {u}int{8,16,32}_t types are defined vary between both libc
implementations and across architectures we need to utilize the PRI
defines.

Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.
Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.
Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file. Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Remove the type field from the sensor value structure. All values will
have the type previously defined by SENSOR_VALUE_TYPE_INT_PLUS_MICRO.
This simplifies the interface, as apps will know what value type to
expect. Apps that prefer to use double values can optain them using the
sensor_value_to_double function.

PRIMARY, SECONDARY, NANOKERNEL, MICROKERNEL init levels are now
deprecated.
New init levels introduced: PRE_KERNEL_1, PRE_KERNEL_2, POST_KERNEL
to replace them.
Most existing code has instances of PRIMARY replaced with PRE_KERNEL_1,
SECONDARY with POST_KERNEL as SECONDARY has had a longstanding bug
where the documentation specified SECONDARY ran before the kernel started
up, but actually ran afterwards.
