Don't pass pin_type to lookup_pin() - instead, if a pin can be
inverted or can have a pullup, then the caller must explicitly specify
that when calling lookup_pin(). This simplifies the code for the
cases where it is not valid to invert or pullup.
Explicitly pass the pin_type to setup_pin() and have ppins.setup_pin()
apply default pullup and invert flags.

Allocate the stepper_kinematics directly in mcu.py - that way the

Don't issue a get_config command after building the config as the
built config may contain time sensitive initialization commands.
Instead, send the config and init commands immediately after invoking
the build_config() callbacks. This avoids some rare "timer too close"
errors during configuration.

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.

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.

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

Similarly, allow all printer objects to provide a stats() callback.

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
