When the log file does a rollover, start the top of the log with
critical system information (eg, software versions).

Advice users to issue a FIRMWARE_RESTART command on a printer shutdown
event, and remove support for CLEAR_SHUTDOWN. A full mcu reset is
preferable and it simplifies the interface.

Extend the FIRMWARE_RESTART command so that it can use the firmware
"reset" command instead of the "arduino" mechanism.

Now that the mcu objects can be created prior to connecting to the
mcu, it is no longer necessary to separate the init and build_config
phases in the high-level code. Move the mcu objection creation from
the build_config phase to the init phase and eliminate the
build_config phase.

Add initial support for micro-controller resets via the Arduino reset
mechanism. Also, automatically attempt a firmware restart if the
printer CRC does not match.

Report in the log the host CPU type and count. This helps distinguish
between different rpi versions when debugging the log from a problem
report.

The normal system clock can have sudden jumps if the system clock is
changed. Use the system monotonic clock to avoid these sudden changes
in time.
It appears the Raspbian OS (which is used by OctoPi) is setup to
update the system clock upon network connectivity. This could cause
sudden system clock changes which could lead to Klippy processing
errors. Using the monotonic clock eliminates these issues.

Check for msgproto.error and warn the user about version firmware
version mismatch. Raise msgproto.error when extracting firmware
constants.

It is possible to restart the host software with a RESTART command
after manually resetting the micro-controller.

Add a "restart" gcode command that will cause the host "klippy"
software to reload its config and restart.

The set_printer_ready() method can be called from a background thread.
Have the main Printer class call a new dump_debug() method in the main
thread on a shutdown event.

Check that all options specified in the config file are valid. This
catches possible typos and spelling errors in variable names that have
a default.

Add helper function that ensures a config option is one of several
choices. This helps ensure that a proper error is raised if an
invalid choice is made.

Use the greenlet mechanism to wait for the connection to come up in
the serial connect() method. This simplifies the calling code.

Setup the reactor and run the MCU connection code as a timer within
the reactor. The connection code will make use of reactor greenlets
so that it can wait for events during the connection phase.

Writing to the debug log can cause an unbounded delay due to disk IO.
This is particularly so on embedded machines such as the Raspberry Pi
that run on SD cards. These log writing delays can cause problems for
the main processing threads.
The new "queuelogger" code forwards all the main thread log messages
to a queue, and a background thread writes the log messages from the
queue to the destination file. This eliminates the IO delay from the
main threads.

Create a new python file (extruder.py) to control the extruder heater
and stepper motors. This separates the extruder control logic from
the cartesian robot code - making it easier to customize both the
kinematic control of the robot as well as the extruder.
