df870da929 avr/chaos: die(), fix read_adc() 
die(): 'W" 0xd1ff   causes infinite uninteruptable sleep.
Fix adc_sum shift.
Properly account for the new adc_sum format.
Do not fault read_adc() when wdt_tick.

de6e5d2e1d avr/chaos: WDT reboot handling 
Interrupts were never enabled unless 'W'.  The WDT was enabled via init_conf().
Result was constant rebooting.

Enable interrupts unconditionally in the main loop.
On boot, detect WDT reset, disable the WDT, chain load a WDT config.
Cmd 'Z' to read the `MCUSR` with the `WDRF`.

Detect WDT interrupts during `spi_slave_Rx()`, answer with an error 'EEW'

`adc_lock` to prevent the WDT ISR to call read_adc() when it is busy.
Also, `read_adc()` will discard the result in case of a `wdt_tick`.

Configure dac_nominal=700V with hvosc 55,14.

23194ceabb avr/chaos: hv_led improvements, spi_busy, … 
- Do not toggle the HV LED at every command.
- Toggle with 'W' and 'H'.
- Remove `conf.wdt_save_addr`.
- Add `conf.wdt_toggle`, toggle period of the HV LED in ISR.
- 'H' etc turns the LED on, `hv_led_on()`.
- At boot, only do `hv_safe()` when `conf.safe` (EEPROM[0]).
- 'r' 1 reads `adc_hv`
- Sanitize arg `read_adc(…, n)`
- `spi_busy()`, break out of long loops when SPI SSEL is asserted.
- `clear_spi_busy()` in the main loop, when SSEL is asserted,
  answer with a busy message.
