Kevin O'Connor c9b44b5bb6 serialhdl: Support working with pseudo serial devices
Support working with devices that aren't really serial ports and thus
do not have a baud rate.

Kevin O'Connor 565861f680 reactor: Support pause() command even when the reactor is not running
If the reactor isn't running then implement pause using the system
sleep command.  This simplifies the users of pause().

Catch the right exceptions so that a retry is possible when attempting
to open the serial port.

Kevin O'Connor a38437f378 stepper: Introduce stepper_get_position command and remove from endstop.c
Move the logic to calculate and report the stepper's current position
from endstop.c to stepper.c.  This localizes the stepper code into
stepper.c.

Kevin O'Connor 64407dc5d2 klippy: Support FIRMWARE_RESTART command
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.

Kevin O'Connor c19af4fb2b serialhdl: Load the mcu's 64bit clock at start of connection
Store a full 64bit uptime in the mcu and query it at the start of each
connection.  This ensures the host's 64bit clock is always in synch
with the mcu's clock.

Kevin O'Connor 20d0936fa2 reactor: Use the system monotonic clock instead of the normal system clock
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.

Kevin O'Connor c552ba06b4 serialqueue: Remove serialqueue_flush_ready()
The serialqueue_flush_ready() code was used to flush queue_step
commands during a homing operation.  It's no longer necessary now that
moves during a homing operation use the normal message priority
system.

Kevin O'Connor fe95ea221b build: Define DECL_CONSTANT mechanism for defining exported constants
Add a DECL_CONSTANT macro to allow the firmware to define constants
that are to be exported to the host during the "identify" phase.  This
replaces the existing hardcoded mechanism of scanning the Kconfig
header file for certain constants.

Kevin O'Connor 74fa8a3907 serialhdl: Clear "hupcl" bit from serial port
The arduino style serial port interfaces can reset the MCU when the
serial port is opened.  Clearing the HUPCL flag makes this less
likely.
