The set_printer_ready() can be called from a background thread on a
shutdown event, so don't try to lookup the printer components in that
case. Simplify build_handlers() so that it no longer tests for
components being available - test for component availability in the
command handlers.

Always call the regular .parse() method for each message type during
dump() - add a new .format_params() method for dumping a verbose
representation of the parsed message. This allows the new
format_params() to also be used with data already parsed.

The Klipper software has progressed to the point where it does not
need to be described as "experimental" software.

Detect avr gcc v4.8.1 and then disable warnings during the klipper.o
linking to suppress bogus "misspelled signal handler" warnings.

Support a "make flash FLASH_DEVICE=/dev/ttyACM0" rule with the default
commands for flashing a device.

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.

Always log the last synchronized clock during a shutdown event, and
use debug level for normal reports.

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.

Move the PWM, ADC, and SPI pin tables closer to their corresponding

Add the new item at the same time as checking if there is space in the
queue.
Also, update the default optimization level of c_helper.so to O2 to
improve the compiled code layout.

Calculate where a tower must reverse direction during a move in the C
code instead of the delta.py kinematic code. This simplifies the
python code.

The delta code calculates a "virtual tower" along the line of
movement. Rework the variable names and comments to make it clear
that this is occurring.
It is not necessary to pass the start_pos variable to the C code as it
is simple to update the start_pos at the start of each movement.

It's not necessary to have separate C delta kinematic functions for
constant acceleration and constant velocity as constant velocity can
be obtained by using a constant acceleration of zero.
Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
Update the C delta kinematic code to take velocity and acceleration
directly in step distances and clock ticks. This simplifies the
mcu.py python code as it only needs to do unit and axis conversion.
