Marc-Antoine Ruel daad425c63 ssd1306: implement SPI and transparent differential update. 
- Increase test coverage to 100%.
- Add ssd1306smoketest.
- Complete SPI 4-wire implementation.

Differential update reduces the amount of data sent over the I²C/SPI bus at the
(small) cost of slightly more CPU usage. On many platform, I²C default transfert
speed is only 100KHz so when only a small section of the display is updated,
this can lead to significant performance improvement.

For now only page based differential update is used, as column based offset
corrupt the display. This still results in large savings.
