It's common to add commands that dispatch to a particular object
instance depending on the value of a command parameter. (For example,
the command "SET_SERVO SERVO=xyz" wants to be handled by the
particular "xyz" servo instance.) Add a register_mux_command() helper
to gcode.py make it easier to do this.

Raise an error during config parsing if the position_endstop is not
between the position_min and position_max. This avoids a confusing
error message during homing.

For some reason, Linux creates the pseudo tty with group writable
permissions, but not group readable. Use chmod to allow the device to
also be group readable.

The step speed rounding and the cpu delay must be run after running
the endstop specific preparation code. Otherwise, a delay in the
home_prepare() code could undo those calculations. Specifically, this
could lead to errors on a multi-mcu setup when the Z is homed using a
virtual_z_offset and there is a delay in the activate_gcode section.

In order to properly delay BACKGROUND_PRIORITY_CLOCK messages, they
must be 5ms beyond the minimum defined by MIN_REQTIME_DELTA. So, add
both MIN_REQTIME_DELTA and MIN_BACKGROUND_DELTA to the timing of these
messages.

If the clock querying messages occur at a similar frequency to other
events on the micro-controller or host, then it's possible for the
load created by those other events to skew the clock synchronization.
In particular, the 500ms lcd screen update could resonate with the 1
second clock query. Use an unusual clock querying frequency to avoid
this issue.

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.
Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
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

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.

lookup, allow multiple ranges to be defined. This makes the lookup
more accurate when a full lookup table is available.

If the c3 coefficient is negative it can cause the adc calculations to
