Add a system startup script so that Klipper can automatically start at
boot time. Create an installation script that will install the system
dependencies and the startup script.

No need to recommend users disable "SD card support" in octoprint -
instead, just ignore the M21 command.

Debugging file.

Rename sched_timer_kick() to sched_timer_dispatch() and move its loop
into its callers in the board code. This eliminates the need to
export timer_try_set_next() from the board code.

Introduce a TICKS() macro during config parsing that will translate
time in seconds to time in clock ticks.

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.

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.

Allow sendf() to be called from irq and timer context - check for the
case where sendf() is called while already in sendf() and simply
discard those messages. This makes it safe to use output() debugging
calls even in irq and timer context.

Change the default compression error window (max_error) from 50us to
25us - it's common for stepper motor drivers to have 30us for their
"pwm fixed off time" and it would be good for the steps to be
scheduled within that time.

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.

Use a more real-world example to improve the description of message
block contents. Make it more clear that the data dictionary contains

Various installation updates. Recommend upgrade to OctoPrint v1.3.0.
Recommend configuring OctoPrint to not disconnect on error. Note
quirk with needing to reload page if "/tmp/printer" not in list of
serial connections. Add brief documentation on use of extended
commands and checking for errors.

Support human readable commands (eg, "help"). Add a "help" command to
list these extended commands.
Also, add support for declaring command aliases, command help, and
command availability next to the handlers themselves.

Check that all options specified in the config file are valid. This

Instead of writing error messages to stderr, route them into the

still allowing regular reactor events to occur.
