Extend the ADC out of range check so that it is possible to sample
multiple times before going into a shutdown state. This reduces the
chance that measurement noise will cause an error. In an actual over
temperature (or under temperature event) it is expected that the
sensor will consistently report the problem, so extra checks for an
additional second or two should not substantially increase risk.

Add support for an itersolve_set_position() function that sets a
stepper position from a cartesian coordinate. This eliminates the
need for both the python and C code to be able to translate from a
cartesian coordinate to a stepper position.

All the kinematic code now uses the iterative solver to generate
steps. Remove the old stepcompress_push_const() mechanism.

In some rare circumstances it was possible for the host software to
become so busy that it does not transmit a get_clock request for
several seconds. (In particular, this could occur with some complex
calls to coordinate_descent.) If that happened, it was possible for
the code to incorrectly report a "Timeout with MCU" error. Rework the
is_active() check to prevent that.

Normally, the MCU is restarted on a config change. However, that
should not be done automatically if the MCU is in a shutdown state.

Most callers did a lookup of the pins module via
printer.lookup_object("pins"). Use that as the standard method and
remove these less frequently used methods.

Add a lookup_command() method to the SerialReader class that provides
a wrapper that stores the serial and commandqueue references. This

Instead of using the toolhead class to determine if stats should be

Specify hardware pwm cycle times using the same method as software pwm

If the mcu supports command restarts and it does not appear to use a
real serial port, then default the restart method to 'command'. This
is a better default on boards with native USB support.

Allow a set of g-code scripts to be run on each probe invocation.
This may be useful for probes that need to be setup before they are
useful (eg, with servo actuated probes).

Instead of hardcoding which objects are called on state transitions,
allow any "printer object" to be invoked if it has a printer_state()
method. Convert connect, ready, shutdown, and disconnect callbacks to
this mechanism.
Similarly, allow all printer objects to provide a stats() callback.

Add get_reactor(), lookup_object(), lookup_module_objects(), and

It's valid to consider the stepper at a position that is not on a step

Make sure to always call MCU_endstop.home_wait() if
MCU_endstop.home_start() is invoked. Rename
MCU_stepper.note_homing_triggered() to note_homing_end() and make sure
it is always called if MCU_stepper.note_homing_start() is invoked.
With these changes, MCU_endstop.home_finalize() is no longer needed.

If an MCU signals a shutdown from the background thread, notify the
