Move the C code out of the main klippy/ directory and into its own

Add a set_shutdown_speed() method so that the heater_fan code does not

The M206 command is confusing (it uses negative offsets) and isn't
very flexible. Add a new SET_GCODE_OFFSET command to make it easier
to add virtual offsets to gcode commands.

The M206 command is confusing as positive values in that command
result in negative offsets to future g-code commands. Perform the
parameter negation in the M206 command instead of storing it that way
internally.

When using an automatic probe, limit the Z lift speed to be no greater
than the Z probing speed. This can reduce Z jerks during probing.

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.

If max_accel_to_decel is greater than max_accel in the config, then
just internally limit max_accel_to_decel to max_accel. This makes it
easier to completely disable the max_accel_to_decel feature (as it can
just be set to a high value in the config).

Add a fully functional STM32F1 port, currently mostly targeting STM32F103
microcontrollers. This requires an 8 MHz XTAL. The maximum possible step rate
is around 282K steps per second.
This uses stm32flash to burn the firmware. The bootloader needs to be started
by setting BOOT0 to 1 and resetting the MCU. There is no automatic bootloader,
unlike on Arduino.

Instead of supporting a single linear range for the temperature
lookup, allow multiple ranges to be defined. This makes the lookup
more accurate when a full lookup table is available.
Update the AD595 sensor to use the full table defined in its spec.

If the c3 coefficient is negative it can cause the adc calculations to
fail. The c3 shouldn't be negative in practice, so fallback to a
simple beta calculation in that case.

Move the Thermistor code to a new thermistor.py module. Move the
Linear code to a new adc_temperature.py module. This simplifies the

The Thermistor (and Linear) class should handle all the details of
reading the ADC values and converting them to temperatures. So, move
that logic out of the Heater() class.

Add a PrinterHeaters class that can stores references to available
temperature sensors and stores references to instantiated heaters.
Add a extras/heater_bed.py file and delay instantiation of the
heater_bed object. This allows the heater.py module to be imported
earlier during the setup phase, and allows the PrinterHeaters class to
be available for registering sensors and heaters.

The existing junction algorithm limits the speed between two moves by
determining the maximum speed an arc between those two moves would
have if the cetripetal acceleration of that arc did not exceed the
printer's maximum acceleration.
However, should the slicer send an actual arc to the printer, then the
existing junction algorithm would not impose any significant limit on
the travel speed of that arc. This would permit the head to travel in
a circle at high velocity and with a greater centripetal acceleration
than the printer's maximum acceleration. To avoid this, impose a
limit on the junction velocity of short moves so that an approximate
centripetal acceleration of that move does not exceed the move's
acceleration limit.

If a heater falls out of the target range, accumulate the temperature
differences to determine if an error should be raised. This should
make it less likely to report an error for heaters that drift slightly
out of range, and it should make error reporting faster for heaters
that rapidly fall out of range.
