1) Bus error will be thrown on read/write errors with errno set. (Read didn't used to fail at all.)
2) try_lock correctly returns boolean whether lock was grabbed.
Fixes #87

The new sequence is as follows:
* Solid blue during the boot/settings script.
* Solid green during the main/code script.
* After main while waiting to enter repl or reset:
* Fading green once main is done successfully.
* On error produce a series of flashes:
* Long flash color of script.
* Long flash color of error:
* Green = IndentationError
* Cyan = SyntaxError
* White = NameError
* Orange = OSError
* Yellow = Other error
* Line number of the exception by digit. Number of flashes represents value.
* Thousands = White
* Hundreds = Blue
* Tens = Yellow
* Ones = Cyan
* Off for a period and then repeats.
At any point a write to the flash storage will flicker red.

Add try_lock and unlock to I2C and SPI classes to make sure things2016-12-02T23:46:12+00:00Scott Shawcroftscott.shawcroft@gmail.com2016-11-30T23:08:34+00:00urn:sha1:26229efe78f6c5f8598d6f9f1b2261c5a84d7a7b
are shared well between threads and underlying MicroPython (SPI Flash
for example.)
It is recommended to use the bus device classes to manage the locks
and other transaction state.

Docs are here: http://tannewt-micropython.readthedocs.io/en/microcontroller/
It differs from upstream's machine in the following ways:
* Python API is identical across ports due to code structure. (Lives in shared-bindings)
* Focuses on abstracting common functionality (AnalogIn) and not representing structure (ADC).
* Documentation lives with code making it easy to ensure they match.
* Pin is split into references (board.D13 and microcontroller.pin.PA17) and functionality (DigitalInOut).
* All nativeio classes claim underlying hardware resources when inited on construction, support Context Managers (aka with statements) and have deinit methods which release the claimed hardware.
* All constructors take pin references rather than peripheral ids. Its up to the implementation to find hardware or throw and exception.
