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.

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.

Add support for directly printing from a local file on the host. This

Instead of using the toolhead class to determine if stats should be
reported, allow every printer object with a stats() callback to
determine if stats are needed.

OctoPrint (and other software) will sometimes send additional commands
even if the previous command has not yet responded with an "ok".
Change the g-code input reading code to keep reading input so that an
M112 can be detected (and processed out-of-order). To avoid the
extreme case where one writes an entire g-code file to the input
without any pacing, disable the input reading if more than 20 commands
are pending.

Instead of hardcoding which objects are called on state transitions,
allow any "printer object" to be invoked if it has a printer_state()
method. Convert connect, ready, shutdown, and disconnect callbacks to
this mechanism.
Similarly, allow all printer objects to provide a stats() callback.

Add get_reactor(), lookup_object(), lookup_module_objects(), and
set_rollover_info() to the main Printer class so that callers do not
need to peek into the class' members. Similarly, add get_printer()
and get_name() methods to the ConfigWrapper class.

If an MCU signals a shutdown from the background thread, notify the
main thread and handle the shutdown there. Dispatch shutdown handling
from the main Printer() class instead of from the Toolhead class.
This simplifies the shutdown logic.

Continue to sample the ADC input pins even if the MCU goes into a

Commit d0932009 changed the way command handling was performed, and
commit 95950949 fixed a defect in that commit. Unfortunately, the fix
was incomplete.
If multiple commands were sent to Klippy without waiting for an "ok"
response from Klippy, then it was possible for those additional
commands to be queued and processed after subsequent commands. This
would result in commands being processed out of order.
Fix this by only reregistering the input fd in the greenlet that
performs the unregistration of the fd.
