Rewrite the i2c module to be based around the MRAA C++ API,
since this makes resource management easier inside of the UPM
C++ classes.
i2clcd.{h,cxx}: remove the close() function. This now automatically gets
called when the object goes out of scope, inside the destructor.
examples/i2clcd: fix C++/Python/Javascript examples that explicitly called the close function.
The I2c context now gets called by the destructor of the sensor class. This
happens when the object goes out of scope or when it gets deleted, if the
object was created using the new keyword, as is the case here.

the raw MRAA function directly instead and remove the helper functions from the
I2CLcd class
