3972bc19c7 atmel-samd: Basic capacitive touch button support.
Currently only works on a single channel and is only enabled for boards with
SPI flash. Only really designed for hardware testing at this point.

b6f1eebab3 atmel-samd: Add APA102 support and flash more advanced status.
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.

Fixes #63

0ae344841f atmel-samd & esp8266: Make sure pins are not already in use.
This prevents corrupting previous functional objects by stealing their pins
out from under them. It prevents this by ensuring that pins are in default
state before claiming them. It also verifies pins are released correctly and
reset on soft reset.

Fixes #4, instantiating a second class will fail.
Fixes #29, pins are now reset too.

ccbb5e84f9 This introduces an alternative hardware API called nativeio structured around different functions that are typically accelerated by native hardware. Its not meant to reflect the structure of the hardware.
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.

5b3a143ffe atmel-samd: Rework tick timer to use TC5 and support neopixel status LED.
The tick timer needed to be reworked because the ASF delay functions also
use the SysTick timer. Now, it uses TC5 and calls out to the autoreset
logic every tick. Fixes #43.

Added neopixel status colors and corrected the latch time from ms to us.
Fixes #42.

d189a3f3cf atmel-samd: Support auto-reset based on USB write activity.
It will soft-reboot micropython after a burst of writes to the
file system. This means that after you save files on your computer
they will be automatically rerun.

This can be disabled in the build by unsetting AUTORESET_TIMER in
mpconfigboard.h.

Using the REPL will also prevent the soft resets until you reset
with CTRL-D manually.

7d8929c470 atmel-samd: Add I2C support.
This commit also introduces a new shared-bindings directory which is used to store the common Python -> C binding code. By having a shared directory we can ensure that the Python API across ports is the same. Each port will have a corresponding common-hal directory which provides definitions for the C api used in the shared-bindings code. That way the compiler can enforce the C api.

To migrate to this new shared API create a common-hal directory within your port and change the Makefile to compile both the shared-bindings and common-hal files. See atmel-samd/Makefile SRC_BINDINGS for an example.

0c4f9b878a Enable REPL over USB.
All of the code was there except the linker was failing to clear the bss section because I added too many .zeros. The should have only been the exported globals that start with _ like _szero = .. Fixing that and turn on the usb transmit fixed everything.

8f26d181c3 Blinking the LED works. Clocks should be set up correctly.
Everything works fine without USB being plugged in but faults (I think) when USB is plugged in. This is switched away from the USB code from the bootloader onto the USB code thats generated by Atmel Studio using the high level classes from ASF.
