[communication] Disables interrupts for arduino in superbus' I2C receive interrupt routine.
[communication] Improves the superBus over I2C performances.
* Modifies the I2C_send@lib_I2C_arduino.cpp to take into account the fact that arduinos are sending data over I2C faster than what they can receive. This test must also be implementented in the LPC I2C driver for superBus.
* Corrects one warning.
* Adds size check in memcpy.
