The PRU code size has grown too close to the maximum - remove the ADC
code to reduce its overall size. (On the beaglebone, the Linux
process can, and typically does, do the ADC reading.)

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.

Calculating the cartesian position from the stepper positions can be
complex and cpu intensive, so rename it to calc_position() to be more
descriptive.

When using multiple micro-controllers it may be necessary to use an id
from /dev/serial/by-path/ instead of /dev/serial/by-id/. Also,
emphasize that in config/example-multi-mcu.cfg.

Change the get_status command to get_clock. Don't report the shutdown
status in the new get_clock command.
The primary purpose of this change is to force the host code to report
a firmware version mismatch with older firmwares as recent changes
(namely the ordering of message block acks) have subtle
incompatibilities if different host/mcu code is used.

Use the new gcode.register_mux_command() so that SET_PRESSURE_ADVANCE
works correctly with multiple extruders.

and bus mode. Add support for sending SPI messages on shutdown.

Move the C code out of the main klippy/ directory and into its own
directory. This reduces the clutter in the main klippy directory.

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.

Drop support for M303 and PID_TUNE, and replace it with a new
PID_CALIBRATE command. Move the logic for this command from heater.py
to a new pid_calibrate.py file in the extras/ directory.

It looks like OctoPrint is expecting the result from M114 to be
relative to the last G92 command. Also, introduce GET_POSITION to
report the actual location that the printer is at.

Emphasize that the log file needs to be attached to the issue.
Encourage M112 to be issued on every bug report.
