sysfs usually appends newlines at the end of attributes to make them
easier to consume, but the test suite can't test for that.

From Coverity:
iio-sensor-proxy-3.3/src/iio-buffer-utils.c:435: dont_call: "fscanf" assumes an arbitrarily long string, so callers must use correct precision specifiers or never use "fscanf".
This also fixes the temp variable being reused to parse the contents of
the sysfs file before being freed. How this behaves depends on the
length of the sysfs file path and the length of the string inside the
file.
On error, the channel info would just be left unfreed.

WARNING: You should add the boolean check kwarg to the run_command call.
It currently defaults to false,
but it will default to true in future releases of meson.

In c7fb43e0, we added a buffer driver for ambient light sensors, but we
added it to the list of drivers in a way that would favour polling
drivers. Since we started using IIO_SENSOR_PROXY_TYPE to tag devices,
and as those can support multiple drivers, we need to prefer the buffer
driver as it's the one that doesn't require constant monitoring.
This also fixes operations on some Dell laptops where the polling driver
is completely broken.

Check whether a particular user/D-Bus client is allowed to claim a
sensor.
The ClaimCompass method on net.hadess.SensorProxy.Compass doesn't have a
check as only the geoclue user is allowed to access this interface, as
per the D-Bus configuration.
Reimplement iioutils_get_param_float() to parse float data like it would
in the C locale. This fixes the scale being '0' for every axis on some
systems and in some locales.
This is used to get the scale and offset parameters from buffer IIO drivers.
