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_.

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.
