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.
Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
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.

Now that homing is implemented via "drip moves", it is no longer
necessary to round the homing speed and it is no longer necessary to
add a delay for cpu processing time.

Rework the low-level implementation of homing movement. The existing
mechanism buffers all homing movement into the micro-controller prior
to starting the home. Replace with a system that buffers all movement
into the host look-ahead buffer and then "drip feed" those moves to
the micro-controllers. Then clear the host look-ahead buffer when all
endstops trigger.

Finish Moves needs be a hard requirement for the event gcodes, as it eliminates the possiblility of an event firing while the gcode is executing.
