Large increases in fan speed can suffer from acceleration lag, so this
change kick starts the fan for a change of 50% or more in the same way
that starting the fan from 0% does.

Support averaging the extruder position over a time range to "smooth
out" the velocity changes that occur during pressure advance.

Now that the tmc drivers perform automatic soft stepper enabling,
there is no need to be able to list multiple pins in the enable_pin
config setting.

Do not apply max_extrude_cross_section check, and do apply
extrude_only_xxx checks to Z only moves that also extrude. Some
printer start scripts will prime the extruder while moving the Z.

Move the common temperature amplifier config descriptions to

Also, minor changes to wording of some example-extra.cfg sections.

Below off_below the fan will be turned off. When configured correctly this
can prevent stalling, which may lead to overheating and failed fans. To
simplify calibration and use of this setting, off_below is applied in the
input duty cycle domain, prior to any scaling due to e.g. max_power.

Some users increase max_extrude_cross_section to avoid issues with
some slicers. However, increasing that value also increases the
defaults for the max_extrude_only parameters which is not obvious.
Base the max_extrude_only defaults only on the configured nozzle
diameter.

Commit b0d859f2 introduced a second_homing_speed parameter, and it
also changed the retract speed. Revert the retract speed change (use
homing_speed when the head retracts).

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.

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.

If the fan's max power is limited by the config, then scale speed
requests between 0 and max_power. This makes more sense for typical
g-code fan speeds.

Move the description of stepper phase adjusted endstops to a new

Specify hardware pwm cycle times using the same method as software pwm
(in seconds, not clock ticks). Allow the fan code to be configured
with an explicit cycle time even when using 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.

Added the pwm_cycle_time option for heater config sections. Defaults
to previous value of 0.100 seconds, but may be reduced to shorter times
at the expense of MCU workload and possible MOSFET heating, depending on
controller design. Some printers that need bed PID to be enabled,
notably the Felixprinters series, are known to benefit from shorter
cycle times, as the default 10hz rate results in excessive voltage
supply droop.
While this option can be used on extruder heaters as well, there
is not expected to be any particular benefit from doing so unless
the extruder heater presents a particularly large load.

Add a new config option 'homing_endstop_align_zero' to enable the
