If a soft reset happens while the gamepad module is scanning for button
presses, there is a moment when the pins get de-initialized, but the
gamepad module is still trying to read them, which ends in a crash.
We can avoid it by disabling scanning on reset.

Conflicts:
atmel-samd/main.c
* atmel-samd: Add support for internal filesystems.
This allows us to re-enable `os`. `random` is also enabled because
it solely depends on `os`.
Fixes#266. Its also a pre-requisite for #260.
* atmel-samd: Update SAMD51 linker script comments and MICROPY_MAX_STACK_USAGE enabling.
This saves a lot of RAM. Fixes#287.
Also fixed compilation of frozen_mpy.c to use supplied make rule rather than
builtin rule (supplied rule suppresses printing out the gcc command line).
* atmel-samd: Support patching after updating ASF4.
This makes it possible to automatically fix newer code.
* atmel-samd: Update ASF4 to include flash APIs for SAMD51.
This is the first automatic update that has caused a few deletions
where code was previously copied instead of moved.
This is a prerequisite for #260.
* atmel-samd: Remove ASF3. This will break builds.
* atmel-samd: Add ASF4 for the SAMD21 and SAMD51.
* Introduce the supervisor concept to facilitate porting.
The supervisor is the code which runs individual MicroPython VMs. By
splitting it out we make it more consistent and easier to find.
This also adds very basic SAMD21 and SAMD51 support using the
supervisor. Only the REPL currently works.
This begins the work for #178.
`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.
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.
* 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
* 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()
Reworked frozen module support: clean up makefiles and handle multiple directories.
Modules to freeze are included as git submodules.
Add neopixel to circuitplayground express build.
Fixes#56
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.
