Add a "restart" gcode command that will cause the host "klippy"
software to reload its config and restart.

Support human readable commands (eg, "help"). Add a "help" command to
list these extended commands.
Also, add support for declaring command aliases, command help, and
command availability next to the handlers themselves.

The set_printer_ready() method can be called from a background thread.
Have the main Printer class call a new dump_debug() method in the main
thread on a shutdown event.

Setup the reactor and run the MCU connection code as a timer within
the reactor. The connection code will make use of reactor greenlets
so that it can wait for events during the connection phase.

Don't expose the ADC initialization to the gcode and heater code -
instead, register a callback within the MCU_adc class and call it
directly from the MCU class after configuration completes.

Instead of checking the endstop trigger directly after a retract move,
verify some distance is traveled during the following homing
operation. This reduces the amount of synchronization between mcu and
host during homing.

Should a homing move complete without hitting the endstop, then
disable motors, disable the endstop checking, and report the error to
the user.

Create the Homing class in the gcode handler instead of in the
kinematic classes. This will make it easier to pass error messages
back to the user.

Create the QueryEndstops in the gcode handler instead of in the
kinematic classes. This simplifies the gcode handler as it can
directly register its response callback.
Also, store the stepper name in the stepper class. Also, propagate
the print_time of the query request to the mcu_endstop class.

If the printer is commanded to an invalid location, reset the current
position to the last successfully commanded position.

Rework the code so that the kinematic class (currently just
cartesian.py) has more control over the homing process.

Create a new python file (extruder.py) to control the extruder heater
and stepper motors. This separates the extruder control logic from
the cartesian robot code - making it easier to customize both the
kinematic control of the robot as well as the extruder.
