It adds `board_deinit` when CIRCUITPY_ALARM is set. `main.c` uses it to deinit the board before deep sleeping (even when pretending.) Deep sleep is now a two step process for the port. First, the port should prepare to deep sleep based on the given alarms. It should set alarms for both deep and pretend sleep. In particular, the pretend versions should be set immediately so that we don't miss an alarm as we shutdown. These alarms should also wake from `port_idle_until_interrupt` which is used when pretending to deep sleep. Second, when real deep sleeping, `alarm_enter_deep_sleep` is called. The port should set any alarms it didn't during prepare based on data it saved internally during prepare. ESP32-S2 sleep is a bit reorganized to locate more logic with TimeAlarm. This will help it scale to more alarm types.

Existing movable allocations will also be moved to defragment the supervisor heap and ensure that the next VM run gets as much memory as possible for the GC heap. By itself this breaks terminalio because it violates the assumption that supervisor_display_move_memory() still has access to an undisturbed heap to copy the tilegrid from. It will work in many cases, but if you're unlucky you will get garbled terminal contents after exiting from the vm run that created the display. This will be fixed in the following commit, which is separate to simplify review. 2020-10-13T17:15:34+00:00 Scott Shawcroft scott@tannewt.org 2020-10-13T17:15:34+00:00 urn:sha1:2bc40bcadf36d27d2807ac155f185e6cc55e9ecb 2020-10-13T01:43:21+00:00 Scott Shawcroft scott@tannewt.org 2020-10-13T01:36:18+00:00 urn:sha1:379e73af2e55b1f0c517883360e29d5dbc27a20b Fixes #3504 hopefully. 2020-10-09T19:53:00+00:00 Scott Shawcroft scott@tannewt.org 2020-10-09T19:53:00+00:00 urn:sha1:3ccf644dd0afd85ad8d8c6c67494cebab172b5a8 The issue was that a time.sleep() would set the RTC wake up further into the future even if we wanted to tick every ms. Ticking every ms is used to time the autoreload delay and without it, autoreload doesn't work.
