Introduce a library at system level for sysfs access. The library is used now for the sysfs digitalpin access, pwm pin access, and a new sysfs analog pin system library.
Based on the library - at adaptor level a new generic adaptor was introduced to access e.g. sysfs in a generic way and be able to implement drivers. Beaglebone and Edison are already converted to use the new base adaptor for its AnalogRead() capability.
Manual test
