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.
Now that the stack_error function is truly minimal,
we can check for stack errors much more frequently.
Also move away stack_error from ultralcd to Marlin_main.
Attempt to workaround the M73 C0|D0 visual issue
This is an attempt to enable alternation of time to print finish and time
to color change even in the last minute of time to color change, i.e. be
able to print "0:00C".
The proposed solution leverages the capability of the current FW to read
float values from the C|D parameter. This could have the raw benefit of
being able still to alternate this time on the LCD as "0:00C" (or
"<1min") if the slicer sends a non-zero but <1 time right before the
color change.

- Add parameter `C` to gcode `M73`
- LCD Info screen switches to change time if last `M73` gcode contains `C` parameter
- Examples:
- `M73 P5 R120` will display on LCD ` SD 5% 02:00R ` if it is printing at 100% speed
- `M73 P5 R120 C60` will display on LCD ` SD 5% 01:00C ` if it is printing at 100% speed
Slicers can generate "Time to change/pause/user interaction" using `C<mins:0-65535>` parameter to "overwrite" the remaining print time.
To switch between time to change and remaining time just send in intervals `M73` with or without `C` parameter.
The e/D ratio should be calculated using the extrusion length.
As such, purify the e_D_ratio from the current extruder multiplier in
order to account correctly for flow adjustments.
Move la10c_reset into finishAndDisableStepper, which is called in both
via lcd_print_stop() and indirectly via M84, saving some space.
M84 is checked-for to determine a complete file, so it's a superior
candidate to G80 (which some people avoid due to MBL issues).
enable/disable_z behave differently when PSU_Delta is defined.
During powerpanic and kill however we do *really* need to save energy
and poweroff the motors.
Rename enable/disable_z as poweron/poweroff_z and define some aliases so
that we can use the low-level function where needed.
- In both uvlo_ and uvlo_tiny, calculate Z usteps properly and adjust
the Z position to a true fullstep before disabling the motor. This
avoids shifs during recovery.
- In uvlo_tiny, instead of moving up indefinitely, adjust Z just
once using the smallest move possible (new def UVLO_TINY_Z_AXIS_SHIFT)
- Perform all the uvlo/recovery processing in physical coordinates
and MBL off: there should be no automatic Z movement!
- Disable heaters in both handlers to conserve more power.
- Add timing information to uvlo_tiny too.
- During recovery, to switch between physical and logical positioning
introduce a new "PRUSA MBL" gcode as most of the procedure is
enqueued, and no existing gcode was available.
Correctly cleanup the printer state when stopping the current print:
- Disable interrupts while aborting the planner/queue to ensure
new serial commands are not inserted while aborting
- _Always_ call planner_abort_hard() to interrupt any pending move!
- Clear the saved_target, which might be set when calling stop
from within a paused state. Create a new function to clear the
paused state for future use.
- Do not disable/reset the MBL: doing so will destroy the ability to
restart correctly using M999.
Remove the conflicting and mostly useless card.paused flag (the printing
is either paused, or not) and switch to isPrintPaused only which
accounts for both cases (SD/USB) correctly.
Fix M27/getStatus to show the current real status of the SD print.
Synchronize the queue on M601, as required to precisely pause the print
at the correct instruction.
Alias M25 to M601, which when combined with PR #1899 fixes issue #1614.
Guard against incorrect usage in M601, M602 and M603.
