Rework safe mode and have heap overwrite trigger it.
This creates a common safe mode mechanic that ports can share.
As a result, the nRF52 now has safe mode support as well.

The common safe mode adds a 700ms delay at startup where a reset
during that window will cause a reset into safe mode. This window
is designated by a yellow status pixel and flashing the single led
three times.

A couple NeoPixel fixes are included for the nRF52 as well.

Fixes #1034. Fixes #990. Fixes #615.
