Always log the last synchronized clock during a shutdown event, and
use debug level for normal reports.

Advice users to issue a FIRMWARE_RESTART command on a printer shutdown
event, and remove support for CLEAR_SHUTDOWN. A full mcu reset is
preferable and it simplifies the interface.

Extend the FIRMWARE_RESTART command so that it can use the firmware
"reset" command instead of the "arduino" mechanism.

Move the PWM, ADC, and SPI pin tables closer to their corresponding
code. This is code movement only - no code changes.

Add the new item at the same time as checking if there is space in the
queue.
Also, update the default optimization level of c_helper.so to O2 to
improve the compiled code layout.

Calculate where a tower must reverse direction during a move in the C
code instead of the delta.py kinematic code. This simplifies the
python code.

The delta code calculates a "virtual tower" along the line of
movement. Rework the variable names and comments to make it clear
that this is occurring.
It is not necessary to pass the start_pos variable to the C code as it
is simple to update the start_pos at the start of each movement.

It's not necessary to have separate C delta kinematic functions for
constant acceleration and constant velocity as constant velocity can
be obtained by using a constant acceleration of zero.
Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
Update the C delta kinematic code to take velocity and acceleration
directly in step distances and clock ticks. This simplifies the
mcu.py python code as it only needs to do unit and axis conversion.

Update the set_position() method to convert from millimeters to
absolute step position.
Also, update PrinterStepper.get_homed_offset() and
mcu_stepper.get_commanded_position() to return millimeters.
Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
Now that the kinematic classes call the mcu_stepper with millimeters
and seconds it is no longer necessary for them to directly access the
stepper's position in absolute steps. Rename
mcu_stepper.commanded_position to mcu_stepper._commanded_pos to make
clear it is not a variable intended to be externally accessed.

Rework the parameters of step_delta_const() and step_delta_accel() so
that they take velocity and acceleration directly in millimeters and
seconds. This simplifies the delta.py kinematic code.

Extend the endstop code so that more than one stepper can be halted
during endstop homing. Some kinematic setups (eg, corexy) require an
endstop to support this.
