Once a hop is performed, it will only be re-issued if the z-axis has been
moved in the meantime. Usually it is only moved by a z-homing so doing so
will cause safe_z_home to do the hop on the next homing action.
When z-axis is homed, x and y positions are known. When setting this
boolean option, these are set back to their last positions.
Whenever a hop is specified it is re-issued after the Z axis has been
homed. This is especially necessary when a pressure-based probe is used.
Also, the module decides if a hop is necessary, based on either a known
Z position or a flag that is set whenever the motors are disabled.

Previously, when a sercom pin specified the mcu (myname:PIN), it would result in a pin enumeration error.

R Still missing, also might be somewhat dirty since code is converted

During a "drip feed" move, both the move's maximum speed and maximum
acceleration may be limited by the kinematics.

Add a helper class for tracking gpio outputs that are synchronized to
bus updates on a particular command queue.

Rework the spi_config commands so that bus configuration and shutdown
message configuration is done separately from the main "config_spi"
command. This makes the spi configuration more flexible. It's now
possible to use software spi without a CS pin. It's now possible to
define multiple SPI messages to send on a shutdown event.

use SET_GCODE_OFFSET's MOVE=1 parameter in the z offset menu.
Less confusing for people who think nothing happened.

It's not necessary to fully build up the look-ahead queue prior to
starting a "drip move" homing operation. Instead, allow the
look-ahead queue to flush normally.

If the homing move is exceptionally long, it could take a long time
for the host to process the look-ahead queue. Delay the print_time
calculation until moves are ready to be sent.

Rename the commands.
The main reason for this change is to force a micro-controller code
updated (due to important bugfix in 7fefe52d).

The current z_hop support did not work correctly with common slicers
that change Z height between retract and unretract, and it did not
work correctly with slicers that issue a retract at the end of a print
and then at the beginning of the next print.
The z_hop support is therefore being removed until these issues can be
fixed.

Don't default to a Z location of 10, as that could cause damage if the
probe's z_offset is greater than 10. Instead, use the "retract
distance" method that is used for normal multi-sample probing.
Update the PROBE_ACCURACY command parameter names to use the same
parameter names as the PROBE command.

Now that homing is implemented via "drip moves", it is no longer
necessary for the stepcompress code to have special homing logic.
