History
Marc-Antoine Ruel 501558c627 conn/display: simplify Drawer 
display: move devices.Display as display.Drawer

This removes the last interface from devices, which was misplaced due to
historical accident. The new package display will also be the location for an
interface for text output only devices.

Remove io.Writer from this interface. While it's a good performance optimization
for some drivers, it shouldn't be required.

Change Draw():
- Return an error, so that communication erorr can be surfaced correctly,
  instead of an adhoc driver specific Err() method.

'ssd1306' smoke test

Verifies that two SSD1306, one over I²C, one over SPI, can display the same output.

It can also be leveraged to record the I/O to write playback unit tests. It is a good example to reuse to write other device driver unit test.
