Introduce displayio to render graphics to displays.
It's designed to minimize RAM footprint by using Sprites to
represent objects on the screen. The object model also facilitates
partial screen updating which reduces the bandwidth needed to display.

This is all handled in C. Python simply manipulates the objects with
the ability to synchronize to frame timing.

39ee12d1ac Fix os.stat() to use 1970 epoch
Commit 95e70cd0ea 'time: Use 1970 epoch' changed epoch for the time
module, but not for other users. This patch does the same for the only
other core timeutils user: extmod/vfs_fat.c:fat_vfs_stat().
Other timeutils users: cc3200, esp8266 and stm32, are not changed.

Ports that don't use long ints, will still get wrong time values from
os.stat().

eefb6842a0 i2cslave: Fix missing translate() when raising exceptions

Compress all translated strings with Huffman coding.
This saves code space in builds which use link-time optimization.
The optimization drops the untranslated strings and replaces them
with a compressed_string_t struct. It can then be decompressed to
a c string.

Builds without LTO work as well but include both untranslated
strings and compressed strings.

This work could be expanded to include QSTRs and loaded strings if
a compress method is added to C. Its tracked in #531.

* Fix finding translations with escaped characters.
* Add back \r to translations since its needed by screen.

e1b4e9b7c7 UART: Always allocate UART objects in the long-lived pool
Particularly when they have buffers that are written via IRQ or DMA,
UART objects do not relocate gracefully.  If such an object is
relocated to the long-lived pool after its original creation, the
IRQ or DMA will write to an unexpected location within the Python
heap, leading to a variety of symptoms.  The most frequent symptom
is inability to read from the UART.

Consider the particular case of atmel-samd: usart_uart_obj_t
contains a usart_async_descriptor contains a _usart_async_device.
In _sercom_init_irq_param the address of this contained
_usart_async_device is assigned to a global array
sercom_to_sercom_dev which is later used from the interrupt context
_sercom_usart_interrupt_handler to store the received data in the
right ring buffer.

When the UART object is relocated to the long-lived heap, there's no
mechanism to re-point these internal pointers, so instead take the
cowardly way and allocate the UART object as long-lived.

Happily, almost all UART objects are likely to be long-lived, so
this is unlikely to have a negative effect on memory usage or heap
fragmentation.

Closes: #1056

2fbab8067a Prevent freezing USB during high frequency PulseIn.
We now track the last time the background task ran and bail on the
PulseIn if it starves the background work. In practice, this
happens after the numbers from pulsein are no longer accurate.

This also adjusts interrupt priorities so most are the lowest level
except for the tick and USB interrupts.

8d1719f190 Add rtc module
Add an rtc module that provides a singleton RTC class with
- a datetime property to set and get time if the board supports it.
- a calbration property to adjust the clock.

There's also an rtc.set_time_source() method to override this RTC object using pure python.

The time module gets 3 methods:
- time.time()
- time.localtime()
- time.mktime()

The rtc timesource is used to provide time to the time module.

lib/timeutils is used for time conversions and thus only supports dates after 2000.

28642ab10d Add audio output support!
This evolves the API from 2.x (and breaks it). Playback devices are now
separate from the samples themselves. This allows for greater playback
flexibility. Two sample sources are audioio.RawSample and audioio.WaveFile.
They can both be mono or stereo. They can be output to audioio.AudioOut or
audiobusio.I2SOut.

Internally, the dma tracking has changed from a TC counting block transfers
to an interrupt generated by the block event sent to the EVSYS. This reduces
the overhead of each DMA transfer so multiple can occure without using up TCs.

Fixes #652. Fixes #522. Huge progress on #263

43650b6896 Fix PDMIn MEMS microphone support (#479)
Changes:

    * New faster filter loop, by @ladyada. New filter coefficients as well.
    * Turn on microphone clock when PDMIn object is created, and run it all the time, so the user code doesn't have to wait for microphone startup, which can be 10ms or even 100ms.
    * Wait for microphone startup when PDMIn is first created, based on new optional parameter microphone_startup in seconds (takes a float).
    * record() returns number of samples actually recorded, so you can see if it's not keeping up.
    * Fix buffer overflow errors when buffer size was not a multiple of 16 or something like that.
    * Tweak a few peripheral settings.
    * Minimum sampling frequency is now 16kHZ or so, because 8kHz runs microphone at only 0.5MHz, which is too slow for many mics.

Note: I tried 128x oversampling instead of 64x, but the code cannot keep up at 24kHz or above sampling. 128x would reduce the high-frequency noise by 6db.

e3f9ee839a Add frequency changing support to PWMOut.
You can either set it once up front, or set variable_frequency on custruction to
indicate that the frequency must be able to change. This informs whether a timer
can be shared amongst pins.

This also adds persistent clock calibration on atmel-samd. Once the device has
synced its clock frequency over USB it will remember that config value until USB
is used again. This helps ensure the clock frequency is similar on and off USB.

Lastly, this also corrects time.sleep() when on USB by correcting the tick counter.

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.

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.

26229efe78 Add try_lock and unlock to I2C and SPI classes to make sure things
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.

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.

23112a6434 atmel-samd: Merge init into the constructor and check all available
SERCOMs during initialization.

Fixes #16. It was broken because the MISO pin used the second SERCOM.

46e7f8e4fb Documentation rework to unify the docs together rather than having them
on a per port basis.

Also enables generating docs from inline RST in C code. Simply omits all
lines except those that start with //|. Indentation after "//| " will be
preserved.

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.
