f4981677b0 Add a gamepad module for handling buttons in the background. (#295) 
The `GamePad` singleton monitors buttons in the background to make sure a button press is never missed and debouncing happens consistently.

75c3be37ac Re-initialize ADC before every AnalogIn read. (#255) 
`microcontroller.cpu.temperature` uses different ADC settings, and caused
AnalogIn to give wrong answers. AnalogIn can no longer assume it's the
only user of the ADC.

a0d0b27faf Fix issue #207, esp8266 file operations problems (#222) 
The frozen module `_boot.py` was not being loaded on restart
because `pyexec_frozen_module()` did not know about the new `.frozen`
pseudo-directory. Updated lower-level routine to look in the right place.
Also made ".frozen" and related values be `#define`s.

e2f39a8d93 atmel-samd: Remember SPI baudrate. 
This prevents the SERCOM from blipping the data line on each
transaction and therefore fixes #219.

fdb97eda09 Add microcontroller.cpu.temperature, for use as a simple sensor on minimal boards. (#211) 
* Add microcontroller.cpu, the sole instance of microcontroller.Processor.
microcontroller.cpu.frequency is the clock frequency, in Hz.
microcontroller.cpu.temperature is the reading from the internal temperature sensor, in Celsius. None if not available.

* Squeeze firmware size by using -finline-limit. Otherwise non-Express builds were slightly too big.

* Update submodules.

* Fix documentation glitches

266be30777 atmel-samd: Introduce a nvm module for non-volatile byte-level memory access. (#203) 
* atmel-samd: Introduce a nvm module for non-volatile byte-level memory access.

This allows for persisting small configuration values even when the file system
is read-only from CircuitPython.

Fixes #160

* Review feedback:
* Add tests.
* Fix non-zero index.
* Fix len()

fab634e3ee Turn on Rosie CI testing to test new builds on real hardware. 
This introduces a skip_if module that can be used by tests to
determine when they should be skipped due to the environment.

Some tests have been split in order to have finer grained skip
control.

0d2c1bf2bb Fix problems that prevented use of internal frozen modules: 
1. Allow -Wlto-type-mismatch to be just a warning when building with frozen modules.
2. Fix extern decls that triggered -Wnested-externs when building with frozen modules.
3. Pass the correct value of -mlongint-impl to $(MPY_TOOL). New file mpconfigport.mk to do this.

c82b84e0a9 atmel-samd: Fix potential buffer overflow in UART.c by recalculating 
the buffer end rather than naively adding 1. It could have needed to
wrap around. Thanks @dhalbert for spotting the bug.

the future.

a0058e6712 Introduce a random module that is a subset of CPython's random. It 
also initializes in the same way where it takes from a true random
source when available through os.urandom(). After initializing, it
produces deterministic results until the seed is set.

This replaces urandom!

Fixes #139.
