2021-02-25A few minor fixes for corner casesScott Shawcroft
* Always clear the peripheral interrupt so we don't hang when full * Store the ringbuf in the object so it gets collected when we're alive * Make UART objects have a finaliser so they are deinit when their memory is freed * Copy bytes into the ringbuf from the FIFO after we read to ensure the interrupt is enabled ASAP * Copy bytes into the ringbuf from the FIFO before measuring our rx available because the interrupt is based on a threshold (not > 0). For example, a single byte won't trigger an interrupt.

2021-02-23Add state machine divisor checkScott Shawcroft
This causes an exception when setting a state machine too slow or too fast. Fixes #4222
2021-02-23Implement audiobusio and enhance PIO for itScott Shawcroft
This adds I2SOut and PDMIn support via PIO. StateMachines can now: * read and read while writing * transfer in 1, 2 or 4 byte increments * init pins based on expected defaults automatically * be stopped and restarted * rxfifo can be cleared and rxstalls detected (good for tracking when the reading code isn't keeping up) Fixes #4162

2021-02-17raspberrypi: implement os.urandomJeff Epler
Since the datasheet cast some doubt on the strength of the "rosc_hw->randombit", I use the SHA256 hash function to create a high quality random seed from random values of uncertain entropy, as well as to generate a sequence of random values from that seed using SHA256 as a cryptographically-secure random number generator. In practice, it produces over 100kB/s of random data which does not have any gross problems according to _PractRand_.

2021-02-12Enable protomatter on RP2040 buildsJeff Epler
Also found a race condition between timer_disable and redraw, which would happen if I debugger-paused inside common_hal_rgbmatrix_timer_disable or put a delay or print inside it. That's what pausing inside reconstruct fixes. So that the "right timer" can be chosen, `timer_allocate` now gets the `self` pointer. It's guaranteed at this point that the pin information is accurate, so you can e.g., find a PWM unit related to the pins themselves. This required touching each port to add the parameter even though it's unused everywhere but raspberrypi.
