  2. Defer loading the NIF until opening an I2C bus 

    This change moves the NIF load from the time at which the module is
loaded to the time when I2C actually is used.

The primary motivation for doing this is to defer native code crashes
from happening at load time to the time of first use. Load time is
harder to debug and sometimes its not clear which NIF caused the crash.

The calls to `apply` get around some complexity with ignoring Dialyzer
warnings. Dialyzer can't figure out that the recursive looking call
actually invokes the NIF code.

  3. Use nicer atoms for I2C bus errors 

    These errors can happen when the I2C bus hangs or a zero-byte transfer
is tried, but not supported. There are two kinds of timeouts:

* `{:error, :timeout}` - Seen on Allwinner when the I2C bus is hung by a
  device pulling SDA low. If the device tree/Linux isn't configured to
  recover and the SDA line isn't released, then the error will continue.
* `{:error, :retry}` - Seen on Beagleboards (TI AM335x) when the I2C bus
  is hung and there's an attempt to recover the bus.
