Move the "motor_off_timeout" tracking to a new module in the extras/
directory. This makes it easier to customize the idle timeout
behavior.

The junction_deviation configuration parameter has a number of quirks
that make it difficult to configure. Replace it with a
"square_corner_velocity" configuration parameter.

It's rare to have all the Z stepper locations directly under the
printable surface, so using z_positions for points is not a good
default.

Allocate the stepper_kinematics directly in mcu.py - that way the
kinematic classes don't have to interact with the chelper code.

Move extruder.py, cartesian.py, corexy.py, and delta.py to a new
kinematics/ sub-directory. This is intended to make adding new
kinematics a little easier.

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.

Change the simulator to use the generic timer_irq.c and serial_irq.c
code for (dummy) timer and io handling. This is just to make the code
a better example for other developers (most micro-controllers will use
the timer_irq.c and serial_irq.c code).

Switch the host code from the CLOCK_MONOTONIC clock to the Linux
specific CLOCK_MONOTONIC_RAW clock. It's common for ntp to slew the
CLOCK_MONOTONIC clock to account for drift, and that can break the
host's ability to make accurate predictions of the micro-controller
clock. This could lead to "move queue empty" errors. The
CLOCK_MONOTONIC_RAW clock is not slewed and thus should not have this
problem.

Add M117 and M73 to the list of supported G-Codes.
Also, remove M117 from the list of commands reported by the HELP
command as that command is typically only used to list "extended
g-code" commands.

No need to include all the test preparation in the verbose output - as
that can make the output more confusing.

The SPI interface needs to be enabled and configured to the correct
settings of a given oid before CS is asserted. The new function
spi_prepare() allows ports to do that.
This port only introduces the new function in all ports with no
implementation and adds the call to the Klipper generic firmware code.
That means everything still works as before. Ports need to be changed
to fix the underlying issue.
Discussion about the motivation here:

Add basic SPI support and associated documentation.
v2: remove baud rate check, fix baud rate calculations
v3: finish transaction with BSY check, disable SPI when not in use

Add generic temperature smoothing to the Heater class. This is useful
to avoid min_extrude_temp and verify_heater errors due to measurement
noise.
Rename the pid_deriv_time config option to smooth_time so that the
smoothing amount need only be specified once.
