Crash detection is handled at a higher level (which automatically
repeats the current command), however we still need to abort the current
command correctly.
Handle XY crashes by checking the planner status after st_synchronize().
No actual changes done in the function in this, besides break->return.
In G28, simply call the new function instead of using goto, making the
code more readable.
Also remove the senseless comments in G28 about command queuing (dating
back to when G80 was queued instead of being executed).
As done when initializing the printer from a cold start, we need to
clamp the starting position to software endstops before setting the
planner position since 0,0 is frequently out-of-bounds.
This avoids an useless move during recovery that can cause a crash:
- Initial X is set to be 0
- G1 performed by homing will clamp X>=0, resulting in a positive shift
- If X is already at max X (extruder being parked due to PP), this will
slam at X+, causing an immediate crash.
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.

Further restrict babystep insertion when the lcd_update is enabled by
toggling homing_flag when probing Z (where Z shouldn't be touched
anyway as it would disrupt the measurement)
Also reset the encoder value during mesh leveling.
The code around these calls _requires_ that the steps are immediately
processed and/or added to the subsequent planner moves.
The only part that doesn't care about immediate insertion is the
direct user-insertion though the lcd encoder.
Another request from our Service dept. - the user shall be prevented
from skipping the intro wizard, because otherwise some preset/calibrated
features will look like not done - especially live-z calibration.
And since there are users, who send a machine to service to perform 1st
layer calibration only, they must not omit the Z-calibration at the
start after shipping.
As the `M0/M1` moved to the beginning of the parser
- parser would not be able to "find" `M1nn` command if the query was `M1` instead of `M1 `
- to be able to "stop/halt" without sending a string and display default message use gcode `M0`
- as there are no `M0nn` gcodes the parser can query `M0` without additional space needed as in `M1 `
