Yegor Yefremov ff525eb354 dist/tests/if_lib: move testing infrastructure files to a stand-alone package 
Create if_lib package containing all the modules and adapt the *.py files
to import each other using the intra-package references.

The idea behind a package is to invoke test.py either by permanently
modifying PYTHONPATH in user profile via adding path to $RIOTBASE/dist/tests
or make temporary PYTHONPATH changes during the invocation:

PYTHONPATH=$PYTHONPATH:$RIOTBASE/dist/tests python3 test.py

Leave periph_i2c_if.py in the same folder as test.py as this file is
just a Python wrapper around periph specific main.c.

Update BPT memory map. Use definitions generated with the latest code
generator. Both routine names and mapping have changed.

Expected result

This test enables you to test all available low-level I2C functions using the shell. Consult the 'help' shell command for available actions.

Background

Test for the low-level I2C driver. Can be run manually or using python script interface.

Glossary

DEV - The I2C device number, this is usually 0. Consult the board header file for more information.
ADDR - The address of the slave I2C device, this is usually the sensor. Information on the slave address should be found in the sensor datasheet.
REG - The register of the slave device/sensor. Not all sensors follow this access method. A I2C_NOSTOP (0x04) may be needed.
LEN - The length to read or write.
FLAG - Flags set for the I2C, more information is available in driver/include/periph/i2c.h
