Now that homing is implemented via "drip moves", it is no longer
necessary for the stepcompress code to have special homing logic.

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.

Move the serial command wrapper class from serialhdl.py to mcu.py.
This will allow that class to better support higher level

Improve the precision of soft pwm pulses by allowing the host to
directly specify the clock duration of the pulse. This improvement in
precision may be noticeable when controller servos (and bltouch).

Now that enumerations are available, any variable named "pin" can only
be used to describe a gpio pin. Rename the end_stop_state "pin"
parameter to "pin_value". Also, rename "end_stop_query" command to
"end_stop_query_state" to notify users to upgrade both host and mcu
code.

Query the bltouch state during the pin_up command to try and verify
that the probe does actually retract. This may be useful to detect if
the bltouch enters into an "error" state.

Make sure to not query the given endstop until after the start of the
requested operation. This ensures that the operation has started
prior to querying the status of that operation.

Log the details of the MCU prior to attempting to configure the MCU.
This way, the log contains the MCU information even if a configuration

Change the name of the config registration method and pass an explicit
reference to the callback to the new method. This makes the
relationship between mcu registration and build_config() more clear in
the calling code.

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.

All the kinematic code now uses the iterative solver to generate

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
