Partially revert previous change: cancelling a single loop would often
advance the gcode stream to the next wait-for loop if executed at the
beginning of an SD print, implicitly turning off the flag again.
Cancel the loop directly in UnconditionalStop() which stops the command
queue as well in an atomic way, handling this correctly.
Remove most of the duplicated code inside temp_runaway_stop(),
making it identical to the other temperature handlers.
Move the lower-level functions required to stop the entirety of the
machine into UnconditionalStop(). Reuse this function inside
lcd_print_stop().
Set the LCD alert message before calling Stop(), as done in other safety
handlers, so that the error is visible while the printer is stopping.
This also avoids other temporary status messages to appear before
the real issue is shown and/or STEALING the first CRITICAL alert
level before we do.
Use the internal lcd_status_message_level for multiple severity levels
of alert messages.
This is needed to distinguish between non-critical alerts (such as FAN
ERROR) from critical ones (any heater issue). During a failure
scenario, a critical error MUST NOT be overridden by a lower-level one.
As such LCD_STATUS_CRITICAL is currently used for all heater-related
errors that result in a safety full-stop.
Make sure to call lcd_timeoutToStatus.start() when the SD card is inserted
into the printer after it was removed beforehand.

The comment behind the ASM MultiU16X8toH16 was misleading.
It actually computes ((a<<8)*b)>>16, or (a*b)>>8.
Correct the comment and C reference implementation accordingly.
In PR #3093 the progmem array FW_VERSION_NR was introduced to store the
version components, however the code didn't read it properly using the
pgm_read_* functions, making version comparisons fail.
Fix the existing/unused is_provided_version_newer() and reuse it in
show_upgrade_dialog_if_version_newer().
Similarly also read/update correctly the version in the eeprom.
- Move D23 into it's own function inside Dcodes
- Correctly include a break in the switch statement
- Show the dumper status (enabled/disabled) after toggling
- Allow to generate an immediate dump via g-code using D23 E for
symmetry with D20 E
